Professor Sue Ann BidstrupAllen, who joined the Schoolin 1988, has been named theAssociate Chair for StudentInitiatives. The new position wasestablished to help students takeadvantage of opportunitiesprovided by several targetedprograms. Dr. Bidstrup’sprimary responsibilities will focusupon fulfilling the objectivesoutlined in the School’s lastStrategic Plan. These includesupporting and working withstudents pursuing certificateprograms and minors, and assist-ing students enrolled in the Tech

dual-degree program with Spel-man, Morehouse, or ClarkAtlanta University.

Since assuming her new role, Dr.Bidstrup has also been oversee-ing the leadership and adminis-tration of many of the School’sspecial programs, including theDow Research Mentor Program,the ExxonMobil Success Pro-gram, and the B.S./M.S. Program,which is in its first year andcurrently has 12 students en-rolled. She is also guiding initia-tives associated with undergradu-ate recruiting activities.

Students have already noticed theenhancements implementedunder Dr. Bidstrup’s leadership.During a recent help session forintroductory-level courses, a largegroup of students gathered toreceive extra help with particu-larly challenging problems. Onefreshman said “these sessionshave made all the difference.”Another smiled and said, “That’sright. I finally get this stuff.”

Dr. Bidstrup will also continueher teaching and research activi-ties, some of which are profiledon page 4.

From an article by John Toon

Two ChBE professors who havecollaborated for more than 15years on sustainable chemicalprocesses are among thewinners of the 2004 PresidentialGreen Chemistry ChallengeAwards from the U.S. Environ-mental Protection Agency(EPA) and the American Chemi-cal Society (ACS). The awards,which also went to four compa-nies, recognize “creative chem-istry that shows promise forimproving the environment.”

Charles Liotta, who is Tech’svice-provost for research anddean of graduate studies andholds a joint appointment withthe School of Chemistry and

Biochemistry as a Regents’Professor, and Charles Eckert,who holds the J. Erskine Love,Jr. Institute Chair, were honoredfor their development of benigntunable solvents that couple re-action and separation processes.

“We’re using a systems approachto processing,” explained Dr.Eckert. “We are developingmethods that not only are morebenign, but also have economicadvantages in producing betterproducts less expensively.”

For example, they use near-criti-cal water, which when heated to275 degrees Celsius under pres-sure dissolves non-polar organicchemicals that would be insolu-ble at normal conditions.

“You can do areaction withorganic mole-cules, and whenyou want to sepa-rate the products,you just go backto room temper-ature and theyseparate out,”explained Dr.Liotta. Usingnear-critical waterinstead of tradi-tional acid-basedprocesses eliminates the needfor a neutralization step – andthe resulting production ofwaste salts.

Despite recognition for theirresearch, Drs. Liotta and Eckert

say their top accomplishment isgiving their students an educa-tion in multi-disciplinary green chemistry issues.

I have been the Writing ProgramDirector for the School of Chem-ical & Biomolecular Engineeringsince May 2002. My main focusis on improving the written andoral communication skills of theSchool’s undergraduates, with aparticular emphasis on technicalwriting. Primarily, I serve as a co-instructor in the Unit Operationslaboratory course, currently taughtby professor Jeff Empie. I alsoco-teach a ChBE elective course,“Effective Communication forProfessional Engineering,” withprofessor Mark Prausnitz.

In my efforts to improve thetechnical communication skills ofundergraduates, I emphasizethree major areas: coherence,clarity, and concision. Usinginteractive instructional methods,I teach students the best ways toimprove in these three areas, aswell as addressing matters ofgrammar, punctuation, and reportformat. I also require students tomeet with me at least once duringa semester to “workshop” a draftof a report. These individualconferences are the best way forme to address each specific

student’s needs, discuss methodsof overcoming particular prob-lems, and track student progressthroughout the semester.

In addition to coherence, clarity,and concision, I also emphasizethe importance of critical think-ing and constantly encouragestudents to think beyond the“what” of an experiment to the“how” and the “why.”

I followed a somewhat circuitouspath to my current role as theSchool’s Writing Program Direc-tor. I grew up mainly in thesoutheastern U.S. and actuallywent to high school in theAtlanta area. As a child, I alwaysloved reading and writing andused to walk around the housewith an open book at all times.Naturally, I majored in English,and took several fiction writingclasses as well. After receivingmy B.A. from Stanford Univer-sity in 1992, I went on to theStanford Teacher EducationProgram, earning an M.A. inEducation as well as a teachingcertificate. From there, I joinedthe Peace Corps and went toLovech, Bulgaria for two years toteach English to Bulgarian highschool students.

After returning tothe U.S. in 1995, Itaught middleschool in Califor-nia for a whileand then went onto graduateschool at theUniversity of Illi-nois in Urbana-Champaign,where I receivedan M.A. inEnglish literatureand also taughtfreshmancomposition.

In 1999, I moved back down toAtlanta and became a technicalwriter and instructional designerof Web-based training courses,dealing with subjects rangingfrom database administration tohuman resources law. AlthoughI enjoyed my time in the privatesector, I soon found myselfdrawn back to academia again,and was delighted to receive acall from the School to interviewfor the Writing Program Directorposition. More than two yearslater, I am enjoying my rather“unique” role in the department.Most of all, I enjoy getting toknow the students and helping

them to improve their communi-cation skills.

On a personal note, I wasmarried in November of 2002 toBen Snedeker. We are one petaway from the City of Decatur’s5-pet limit (one golden retrieverand three cats). In my sparetime, I like to read, watch C-SPAN, go to the movies, andstock up on red pens.

Air Products and Communications,Inc. has sponsored the ChBE WritingProgram since 1996. The School isgrateful for its stalwart support.

MicroelectronicsSue Ann Bidstrup Allen

Dr. Bidstrup Allen and co-workers in the MicroelectronicsResearch Center are developingnew polymeric systems thatcould revolutionize fabricationprocesses for manufacturingmicroelectronics, microfluidics,and microelectromechanical(MEMs) devices. The core ofthis new technology is based onthe use of a sacrificial polymer,which, upon heating, decom-poses into low molecularweight gases that diffuse out ofthe device, leaving behind airchannels. These air channels

can range from millimeters to sub-microns in diameter. Applica-tions for these air channels include insulation layers between elec-trical interconnects, fluidic cooling channels for thermal manage-ment in electronic packages, and release layers for micro-fabricatedactuators. In addition, the Georgia Tech Packaging ResearchCenter is exploring this technology for the construction of afluidic biosensing platform that uses arrays of micro- and nano-mechanical resonators for detection of biological and biochemicalspecies. This platform will have a wide range of applicationsincluding clinical diagnostics, food processing, environmentalmonitoring, and anti-terrorism.

Dennis W. HessDr. Hess’s research interests arein the areas of thin film scienceand technology, microelectronicdevice fabrication, and elec-tronic materials. Advances inintegrated circuits (ICs) dependon the fabrication of everdecreasing feature sizes (<100nm). Continuation of thesetrends requires that the SiO2(gate) insulator in transistors bereplaced with a higher dielectricconstant material. Dr. Hess’sgroup is investigating the use ofvarious metal oxides, oxyni-trides, and silicates as possiblereplacement layers. Fabrication

of small feature sizes also requires novel processes for film pattern-ing. The group is also investigating the direct formation of thingraphitic structures that can serve as stencils for pattern generation,and the selective growth of film layers by atomic layer deposition.Chemical mechanical polishing (CMP) for surface planarizationdepends on the synergy between chemical and mechanical alterationof a surface. They are developing spectroscopic methods to quan-tify changes in polymer surfaces during CMP. In order to improvethe yield and reliability of ICs, surface cleaning processes are beingdeveloped that use environmentally benign, low viscosity, lowsurface tension super-critical and sub-critical CO2-based fluids.

Clifford L. HendersonDr. Henderson’s researchfocuses on micro- and nano-fabrication, with a strongemphasis on micro- and nano-lithography. Lithography refersto the materials, tools, andprocesses used to fabricate themicron-to-nanometer-scalepatterns that are used to buildmodern microelectronic (e.g.,the microprocessor andmemory chips in personalcomputers) and microelectro-mechanical systems (MEMS).A significant amount of thecurrent work in Dr. Hender-

son’s group is focused on developing new photosensitive and radia-tion sensitive materials that can be used as imaging layers foradvanced, high resolution lithographic processes. In addition, Dr.Henderson and his team are working to expand the use of litho-graphic methods into other fields by developing novel new materi-als and processes for the production of microfluidic (commonlyreferred to as “lab-on-a-chip”) devices and polymeric scaffolds fortissue engineering. As a part of this work, Dr. Henderson’s groupconducts extensive work into the synthesis of new polymeric mate-rials and the fundamental characterization of the behavior of poly-mer thin and ultra-thin films.

Paul A. KohlDr. Kohl and others are creating anew way to power integratedcircuits and other electronicdevices. The work is taking placewithin the Pettit MicroelectronicsResearch Center. The group hasdeveloped a way to integrate thin-film fuel cells into electronicdevices. Liquid or gaseous fuelscan be used in these cells. Theintegration of fuel cells into elec-tronic devices has required acomplete redesign of the tradi-tional fuel cell so as to take advan-tage of the materials andprocesses already used inconstructing electronic devices.

The new fuel cell membranes are much thinner than traditionalmembranes and do not need to be as robust since they are built onto anelectronic substrate. Critical parts of the fuel cell are put in place duringconstruction of the electronic component, such as a sensor. Thisprocess will hopefully lead to low-cost, small form-factor, self-powereddevices. The power and energy output of fuel cells make them espe-cially applicable to sensors and control functions that wirelessly commu-nicate over a local area network. A constant pressure methanol reser-voir has been designed and tested. Hydrogen storage reservoirs, devel-oped by others, can also be used. The technology is being commercial-ized by WiSPI.net (Wireless Self-powered Integrated Networks).

Dr. Arnold Stancell Retires After an Exciting Industry and Academic Career Arnold Stancell, ChBE profes-sor and Turner Leadership Chair,has retired after ten years. Hetaught “Chemical EngineeringThermodynamics II,” was activeon a number of ChBE and insti-tute committees, and wasfrequently sought out by under-graduate and graduate studentsfor academic and career advice.

In his role as Turner LeadershipChair, he initiated the GeorgiaTech Leadership Program, aneffort to introduce leadership andteamwork skills development toall Tech undergraduates.

He received his Ph.D. in Chemi-cal Engineering from MIT in1962 and then joined Mobil OilCorporation in research anddevelopment. He rose throughthe R&D ranks, becomingManager of Chemical ProcessDevelopment. Dr. Stancell then

moved on to the business side –first in planning and then in anumber of management jobs.He worked as the generalmanager of a plastics business, asa regional executive of Europeanmarketing and refining, as a V.P.of the U.S. oil and natural gasbusiness, and as V.P. of theMiddle East, Europe, andAustralia oil and natural gas busi-ness. One of his most memo-rable accomplishments wassuccessfully negotiating an $18billion natural gas joint venturewith the State of Qatar.

Joining Tech was a return toacademia for Dr. Stancell. Hepreviously taught at MIT in 1970on a leave of absence fromMobil, and was offered tenurebut decided to return to business.Among a number of honors, hewas inducted into the NationalAcademy of Engineering in 1997.

Most recently, he was named oneof the “50 Most ImportantBlacks in Research Science” for2004 by Science Spectrum magazine.The selection recognized his“lifelong work in making sciencepart of global society.”

His time on campus led him tobecome an avid Jackets fan whoattended many sports events. Hesays that when he arrived at Tech,he did not understand why therewas a “little” enmity against theUniversity of Georgia. Now, hedoes not care for them either andwill continue to root for the“white and gold” although he nolonger works at Tech.

He will also continue to be activeas Co-Chair of the Board ofChemical Science and Technology(National Research Council),which advises the U.S. govern-ment on a number of issues,

including homeland security. Heis also a member of the advisoryboards for Chemical Engineeringat MIT, Carnegie Mellon, andCity College New York.

Professor Arnold Stancell

The School Welcomes Dr. Rachel Chen Rachel Chen joined the Schoolthis fall as an associate professor.She received her Ph.D. in ChemicalEngineering and a minor in Biol-ogy in 1994 from California Insti-tute of Technology. Her thesisresearch and a brief postdoctoralstint were in the area of metabolicengineering under the mentorshipof the late Dr. James E. Bailey.

Afterwards, she took a researchscientist position with Bristol-Myers Squibb Company in Syra-cuse where she developed interestand expertise in biocatalysis. In2000, she began her first academicappointment at Virginia Common-wealth University as an assistantChemical Engineering professor.

Dr. Chen has broad interests inbiomolecular engineering and hassuccessfully developed projects inmetabolic/cellular engineering,biocatalysis, directed evolution, andgreen chemistry. She has raisedfunds for research and teaching

from the American Cancer Soci-ety, NSF, USDA, and PhilipMorris USA.

Dr. Chen has established the ChenBiomolecular Engineering Labora-tory at Tech and is currentlyrecruiting graduate students toassist her in continuing the impor-tant research she has been pursuingfor several years.

This research is in a very broadfield of biocatalysis and usesisolated enzymes and whole cells ascatalysts in synthesis processes.Through multidisciplinaryapproaches, Dr. Chen addressessome of the most challengingissues in biocatalysis such as thecofactor requirement of manyuseful enzymes, limited substratepermeability imposed by cellularmembranes, and limitations ofnatural enzymes in various aspectsof process applications. Metabolicengineering, directed evolution,molecular modeling and state-of-

the-art molecular biology tech-niques are being applied to addressthese issues.

One of the major focus areas inDr. Chen’s research is the emergingfield of glycomics (glycoscience/glycobiology) concerning carbohy-drate moiety of biomolecules. Theobjective is to develop widelyapplicable biocatalytic synthesismethodologies for complex carbo-hydrates of biomedical interest.These complex carbohydrates arepotential therapeutics for cancersand potential anti-viral, anti-micro-bial pharmaceuticals for variousdebilitating diseases with urgentmedical needs.

Green chemistry is another focusarea in Dr. Chen’s research, and anatural and important applicationof green enzyme/microbial tech-nology. The ultimate goal of herresearch is to reduce reliance forchemical raw materials on petro-leum and to help safeguard the

environment, an issue of greatsocietal importance.

She is a member of the AIChE,the ACS, the American Society forMicrobiology, and the Society forGlycobiology. Dr. Chen is alsothe proud mother of two wonder-ful children, Jennifer and George.In her scarce spare time, sheindulges herself in classical musicand utilizes her creativity in cook-ing and gardening.

Focus on Collaboration The last issue of ChBE News spotlightedTech’s Center for Process Systems Engineer-ing (CPSE), which recently was formed byChBE professors Jay Lee and MatthewRealff as an interdisciplinary venture amongseveral academic units on campus and withthe University College of London’s CPSE.Now, the School is proud to announce thatanother ChBE professor, Mark Prausnitz,has launched a new research and educationinitiative known as the Center for DrugDesign, Development and Delivery (CD4).

From an article by John Toon

The goals of the new center are to betterintegrate the multi-step process involved increating new pharmaceuticals and to focusTech’s interdisciplinary efforts on helpingindustry bring new products to market. Theeffort involves more than 20 faculty membersfrom six different academic areas at Tech.

“One of our goals in this center is to pulltogether these activities in a synergistic wayso the process of bringing a drug to marketwill be more integrated,” says Dr. Prausnitz,director of the center. “By bringing togetherpeople from a variety of backgrounds inscience and engineering, we can provide abroader perspective and understanding of thepharmaceutical development process.”

Georgia Tech has long-standing strengths indrug development and design, as well as inthe complex and demanding chemical engi-neering necessary for specialty chemicals. Inrecent years, it has built a research programin drug delivery techniques – and workingwith Emory University, has grown a largeresearch and education activity in broadareas of biology and biomedical engineer-ing, including genetics, bioinformatics,and proteomics.

The new center will emphasize industrialcollaboration to ensure that its activities havereal-world implications and that its studentslearn skills that will equip them to makecontributions to the pharmaceutical industry.

“We want to work with industry on the mostimportant problems that are going to meet

critical needs,” Dr. Prausnitz says.“To do that, we need to havestrong interactions with industryto guide our research and educa-tion agendas.”

With a background in technolo-gies for delivering drugs throughthe skin, Prausnitz sees a need tofocus on delivery concerns earlyin the drug design process. Thegrowing complexity of drugcompounds and rising impor-tance of gene therapies willmake drug delivery an increas-ingly important concern, he says.

Examples of faculty who are part of theinitiative include:

• Andreas Bommarius, professor in the School of Chemical & BiomolecularEngineering. Dr. Bommarius focuses onimproving biological catalysts to produce drugs such as anti-cancer agents and HIV protease inhibitors.

• Donald Doyle, assistant professor in the School of Chemistry and Biochemistry.Dr. Doyle is developing new drugs against diabetes and cancer using novel techniques to control gene expression by manipulating nuclear hormone receptors.

• Joseph LeDoux, assistant professor in the Wallace Coulter Department of Biomedical Engineering operated jointly by Georgia Tech and Emory University. Dr.LeDoux is designing new viruses that can be safely and efficiently used for genetherapy, especially for diseases of the lung,such as cystic fibrosis.

Beyond research, the center will focus oneducational programs designed to helpstudents at both the undergraduate andgraduate levels understand the needs ofpharmaceutical industry. With funding fromthe U.S. Department of Education’s Gradu-ate Assistance in Areas of National Need(GAANN) program, it has already launcheda program of doctoral fellowships thatsupports 12 students.

McGraw Research Award to hislist of accomplishments.

Established in 1957, the annual award recog-nizes outstanding early achievements byyoung engineering college research workers.The award is sponsored by the EngineeringResearch Council with the assistance of theMcGraw-Hill Book Company.

Award recipients must demonstrate achieve-ment of important advances accepted bycolleagues and others in the field of special-ization with emphasis on quality rather thanquantity as well as sound and productivethinking and with a promise for makingother significant contributions.

Recipients must also be active professionallythrough academic publishing, membership ineducational societies, and developing orimproving laboratory techniques or devices.

Dr. Prausnitz joins a noteworthy group ofprior recipients, including fellow chemicalengineer, Eric W. Kaler, who is the currentdean of the College of Engineering at theUniversity of Delaware.

“The reason we do research isbecause it’s such a good way to train students,” said Dr. Eckert.“Interdisciplinary research is thevehicle for educating studentsabout collaboration and partner-ships to solve problems.”

For Drs. Eckert and Liotta, collab-oration is much more than a prag-matic partnership to win researchcontracts. Though administra-tively part of two differentcolleges, the professors share labo-ratory space and house theirstudents together, mixing graduate

and undergraduate studentchemists and chemical engineersin ways designed to break downtraditional barriers.

“The major social and scientificproblems we will face in the 21stcentury are going to require amulti-disciplinary approach, look-ing at things from a variety ofviewpoints,” said Dr. Liotta. “Ourstudents are educated in coopera-tive and collaborative researchwith other disciplines.” Drs.Eckert and Liotta work in theFord Environmental Science and

Technology Building, which wasdesigned for just that kind ofintermingling. Biologists, chemicalengineers, atmospheric modelers,chemists, and faculty with otherbackgrounds work in adjacentoffices and laboratories, all partof a concerted effort to bringresearchers together around envi-ronmental issues.

The pair met more than 20 yearsago when both were consultantsto DuPont. Dr. Liotta had a repu-tation for work in phase-transfercatalysis, which allows the reaction

of molecules that are not solublein a common solvent. Dr.Eckert’s background was in mole-cular thermodynamics and phaseequilibria, and he was a pioneer inthe use of supercritical fluids forseparations and reactions.

At Tech, they have not onlycombined their respective fields,but also merged their careers.“This has evolved into a fantasticrelationship,” adds Dr. Liotta witha grin. “We just had the rightchemistry to make it work.”

“Chemical Engineering at Tech is always looking ahead,” says SandraAdamson Fryhofer, ChE ‘79, who took some time recently to thinkback to her days at GT. Sandy just came across a memento at hermother’s home: her own diary from her time in the School’s program atUniversity College of London. “It was fun to look through it andremember that summer. I really had a great experience at Tech.”

Sandy says that along with many pleasant memories of her time at Tech,she counts earning her ChE degree among the accomplishments she’smost proud to claim. And that’s saying a lot.

Now a well-regarded internist with a private practice in Atlanta, Sandydreamed of being a doctor as a young girl. She explains that she choseto study Chemical Engineering at Tech because she wanted a “degreethat would mean something” as she prepared for medical school. Also,she felt that a BSChE would provide many other options should hercareer path change. “Chemical Engineering opens an unlimited numberof doors,” Sandy says.

Alumni who were on campus when Sandy was here may remember thatshe earned the title of Miss Georgia while a Tech student. During hertime as Miss Georgia, she was trained for and developed an ease withpublic appearances. After taking a year off related to her state serviceand to compete in the Miss America pageant, Sandy returned to her stud-ies and continued earning high marks.

Sandy graduated from Tech with academic honors, then achieved herchildhood dream by earning a medical degree. She says that her BSChEprovided her “instant credibility” throughout her advanced studies and asshe began practicing medicine. She kept setting her sights high profes-sionally, building a reputation as a physician who listens closely to herpatients and treats their concerns using more than just their medical testresults. In 2000-2001, she served as President of the American Collegeof Physicians-American Society of Internal Medicine (ACP-ASIM), thenation’s largest medical specialty society. She is only the second woman

to be elected President and was thegroup’s youngest president in its 85-year history. Additionally, she wasnamed a Master of the ACP in 2001,joining the small group of highlydistinguished Fellows of the Collegewho have achieved outstandingrecognition in medicine.

Top-notch professional credentialsand her experience with the mediahave led Sandy to television appear-ances as a medical expert onnational and local programs, speak-ing about health-related topicsincluding bioterrorism, anthrax,vaccine issues, heart disease, depres-sion, obesity, and thyroid disease. She easily combines explanations ofcomplicated issues and sometimes contradictory studies with practicaladvice like suggesting to baby boomers that they “be conscious abouttheir retirement health now, before it’s too late, just as they have to planfor their retirement nest egg.”

Sandy is enjoying serving on the Class of 1979 Reunion Committee andspeaks enthusiastically about the changes at Tech since she was here. Shebelieves that students have opportunities for more well-rounded educa-tions now, citing as an example more offerings for international experi-ences like she had through the School.

She remains an advocate of studying in the School, saying that she is“impressed with how the School is on the cutting edge of its discipline.”She keeps track of what’s happening at Tech because of another part ofher life in which she takes great pride: she and her husband have twins,good students who are just starting ninth grade and are active in sportsand fine arts. Though Sandy stays busy and focused on the present,perhaps she is looking ahead to another generation of Yellow Jacketsstudying at Tech.

Gregory Stephanopoulos Delivers the 20th Annual Ashton Cary Lecture

Gregory Stephanopoulos, who is the Bayer Professor of Biotechnologyand Chemical Engineering at MIT, presented the Annual Ashton CaryLecture this spring. He delivered an exciting and informative presenta-tion on “Chemical and Biological Engineering: A New Dimension to aSuccessful Paradigm,” making the 20th annual lecture a memorable one.

Dr. Stephanopoulos’ presentation was especially relevant and timelyas his was the first Ashton Cary lecture to be given since the Schooladded the word “Biomolecular” to its official name. He discussedthe essential role that chemical engineers play in biological researchand emphasized that biology at the molecular level is mostly a chemi-cal science because biological systems and processes are criticallydependent upon the type and extent of chemical reactions occurringin them.

He spoke about numerous areas of biological research, such as theregulation of gene expression, design of antimicrobial peptides andother bioactive proteins, controlled drug delivery, manipulation ofcellular metabolism to maximize productivity, and cell and tissuetargeting for gene therapy. Dr. Stephanopoulos explained that all of

these key research projects are being dissected and optimized usingthe tools of chemical engineering – namely, kinetics, thermodynamicsand transport.

Dr. Stephanopoulos’ long list of professional accomplishments includesauthoring more than 200 publications, receiving 12 patents, and currentlyserving on the editorial boards of seven scientific journals and as theeditor-in-chief of Metabolic Engineering. He has also received numerousawards and honors, including the Dreyfus Foundation Teacher ScholarAward, the Excellence in Teaching Award, and the Technical Achieve-ment Award of the AIChE. He has also been a Presidential YoungInvestigator and the Chairman of the Food Pharmaceutical & Bioengi-neering Division of the AIChE. In 1992, he was a Visiting Professor atthe International Research Center for Biotechnology at Osaka Universityand was elected a Founding Fellow of the American Institute for Medicaland Biological Engineering. He chaired the first Conference on Meta-bolic Engineering and gave the inaugural Bayer Lecture on BiochemicalEngineering at the University of California at Berkeley in 1996. He hasbeen honored with the AIChE FPBE Division Award, the Marvin J.Johnson Award of the ACS, and the AIChE Wilhelm Award in ChemicalReaction Engineering. He was elected to the Board of Directors of theAIChE in 2002 and was inducted into the National Academy of Engi-neering in 2003.
