John F. Brady is the Chevron Professor of ChemicalEngineering (since ’99) at the California Institute ofTechnology where he is also a Professor ofMechanical Engineering (since ’05). In ’75, Johngraduated from the University of Pennsylvania witha B.S. in Chemical Engineering and, after spending ayear at Cambridge University as a Winston ChurchillScholar, entered the Chemical Engineering graduateprogram at Stanford University from where hereceived an M.S. in ’77, followed by a PhD three-anda- half years later. His PhD thesis, under thesupervision of Andy Acrivos, was entitled “InertialEffects in Closed Cavity Flows and their Influence onDrop Breakup”, and dealt with the application ofasymptotic analysis to the solution of severalfundamental problems in viscous flow theory.Following a year as an NSF-CNRS US-FranceExchange Scientist (’80-’81), which he spent at theEcole Superieure de Physique et de ChimieIndustrielles de la Ville de Paris (ESPCI) directed byP-G. de Gennes, John joined the ChemicalEngineering department at the MassachusettsInstitute of Technology as an Assistant Professor. In’85, he was lured away by Caltech where he has beenever since, first as an Associate Professor (’85-’89)and then as Professor of Chemical Engineering (’89-present). He also served as the Executive Officer ofChemical Engineering at Caltech (’93-’99) and was aholder of a part-time Chair in Applied Physics at theUniversity of Twente in the Netherlands (’02-’06).

John is known internationally as one of the brightest,original & most accomplished Chemical Engineers-Fluid Dynamicists for his seminal & wide rangingcontributions to the study of “complex fluids”.

Brady toReceive 2007BinghamMedalProfile by Andreas Acrivos

Examples of such fluids include suspensions,emulsions, colloidal dispersions, ceramics, liquidcrystals, ferrofluids, electro-and magneto-rheologicalfluids, polymer solutions, etc, all having diverse &important scientific and technological applications.

Three of John’s numerous achievements stand out.The first was the creation anddevelopment (together with hisFrench collaborator Georges Bossis)of Stokesian Dynamics (SD) — amolecular-dynamics-like method forpredicting the microstructural andmacroscopic properties of complexfluids. Prior to SD, theoretical studiesof suspensions, which had steadilyprogressed since the original work ofEinstein, had reached an impasseowing to the impossibility of dealing

numerically with the complicated many-particle interactions. The creation of SD, however,radically changed this by providing a computationalavenue to the study of the dynamics of dense dispersesystems which compliments the traditionalapproaches of analytical theory and laboratoryexperiment. Thus, SD ushered in a new era ofinvestigation, not only for suspensions but formultiphase flows generally, in that it allowed one torigorously solve many long-standing problems and,more profoundly, to pose new questions. Also, aremarkable feature of SD is the spectrum of physicalforces (hydrodynamic, electrostatic, colloidal,Brownian, etc.) and the range of length and timescales (tens of angstroms to centimeters and


microseconds to days) encompassed by onetechnique. This method has now been refined to thepoint where it can effectively handle an infinitenumber of particles.

SD has already yielded quantitative a prioripredictions of suspension behavior that are inexcellent agreement with experiments for a variety ofsystems, ranging from the structure, diffusion andrheology of colloidal dispersions, to yield stresses inelectro-rheological fluids, and finally to the self-induced concentration inhomogeneities in pressuredriven flows. More fundamentally, new insights intomicrostructured fluid behavior, such as the profoundimportance of cluster formation, have emerged fromsuch simulations. Ultimately, the understandingbrought about by simulating the relationship betweenthe microstructure and macroscopic properties ofsuspensions will permit the design and engineering ofnovel materials to meet desired applications. All theseadvances have been achieved not only by Johnhimself but by numerous other investigators usingJohn’s code, which he has generously and selflesslyshared, for the asking, over the years.

The second major contribution of John’s in complexfluids is his development of a scaling theory for thediffusive and rheological behavior of concentratedcolloidal dispersions. Specifically, he has shown, in

a series of papers, how the most important effects ofhydrodynamics can be included by a simple rescalingof the time or the shear rate by the concentrationdependent self-diffusivity. This observation has leadto quantitative a priori predictions of the singulardependence of the suspension viscosity on the solidsconcentration at high concentrations, therebyexplaining experimental observations spanning aperiod of over 50 years. This theory also suggests auniversal scaling for the rheological behavior of anysuspension of non attractive particles. This scalinghas also been demonstrated experimentally and canbe used to correlate a vast array of rheologicalresponses displayed by colloids.

The third landmark event in the field of suspensionrheology was John’s development (with P.Nott) of theso-called suspension balance model to serve as aconstitutive equation for the macroscopic descriptionof such systems. Some years earlier, Leighton &Acrivos, motivated by an idea originally due toAscher Shapiro as well as by several earlierobservations by Francis Gadala-Maria, proposed aso-called trajectory model of shear induced particlediffusion which, although somewhat heuristic, wasable to account for a number of puzzlingexperimental results such as the shear-induced re-suspension of heavy particles. In spite of its initialsuccess, however, the trajectory model was found to

Treasurer’sReport

Kraynik, on behalf of Gary Leal and Ralph Colby(Technical Program Chairs, ICR2008) presented areport on the Monterey program. The committeenow consists of Kornfield, Brady, Kraynik, Pine,Hyun, James, Cooper-White, McLeish, Vermant,Vlassopoulos, Mendes, and Watanabe. Nearly everyinvited lecturer has been selected.Kraynik, on behalf of the Chair of the EducationCommittee, Mike Solomon, led a discussion aboutfuture short courses. “Beginning Rheology” (anupdate of the 2004 Lubbock Meeting offering byMorrison and Giacomin, 2-day) will be offered inparallel with “Microfluidics for rheologists” (Squires,Anna and Doyle, 1-day) on the weekend precedingthe Salt Lake meeting (October 6-7, 2007). For theweekend preceding the ICR (August 2-3, 2008),“Introduction to Rheology of Colloidal Suspensions”(Wagner and Mewis, 2-day) in parallel with“Surfactant rheology, self-assembly andmicrostructure dynamics” (Spicer, 1-day) areplanned. The committee is actively solicitingproposals for future meetings.

For Pat Mather (Chair, Local Arrangements), Kraynikreported on the 2011 meeting (October 9-13) at theIntercontinental Hotel and Conference Center inCleveland, Ohio. Everything is nicely falling intoplace.

Faith Morrison (Editor, Rheology Bulletin) reportedthat our latest Bulletin is our largest ever (32 pages).The previously tabled motion “that we allowadvertising in the Bulletin to those not yet advertisingin the Journal of Rheology, while still providing ourdiscount to those who do advertise in the Journal ofRheology.” was then discussed.

Giacomin, Editor for Business, reported on theJournal of Rheology On-Line (JOROL). Usageremains strong. Giacomin reported that we now have57 of the new individual member subscriptions to theJOROL. These, optionally, cost an extra $40 forregular members, and are free to retired members.This new form of subscription is popular. Giacominalso gave an on-line demonstration of journal usagestatistics provided to the Society at www.scitation.org(password protection). AIP has made significantimprovements.

On Pat Mather’s (Chair of the MembershipCommittee) behalf, Kraynik reported that as of year-end 2006, we had 1584 members (including 1368regular and 194 student). Mather is activelyrecruiting new student members.

At 2:30 p.m. Kraynik moved the meeting intoExecutive session. Brady left the room. TheBingham Committee recommendation to award the2007 Bingham Medal to Professor John F. Brady ofCaltech was then unanimously confirmed by the restof the Executive Committee. Kraynik then movedthe meeting back to regular session.Kraynik led a discussion on the creation of newSociety awards.

Giacomin reported that all papers having won theJournal of Rheology Publication Award have beenmade open access. So have all three papers outliningofficial nomenclature for rheology. Open accesspapers can be freely downloaded from the JOROL.

Giacomin reported that the insurance company thatappeared to be misusing the SOR logo to marketitself to SOR members, New York Life, is thedesignated insurance provider for the AmericanPhysical Society Insurance Trust (APSIT). As AIPmembers, SOR members are entitled to special lifeinsurance rates from New York Life. Giacomin hasbeen appointed to the APSIT Board.

At 4:07 p.m. Kraynik againmoved the meeting intoExecutive session. Themeeting was adjourned at4:11 pm.

Treasurer’sReportTo the membership:

Attached are tables describing the financial situationfor The Society of Rheology at the end of calendaryear 2006, along with a proposed budget for 2008.The latter will be presented for the approval of theMembership at our Annual Meeting in Salt Lake Cityin October. Due to a number of positive factors,including higher interest rates, the financial positionThe Society's continues to improve, although thereremain the expected concerns about the InternationalCongress on Rheology in 2008. Budget estimates forthe ICR are around $500,000, which is roughly seventimes a typical Annual Meeting. While we customar-ily budget for a break-even position for meetings andexpect reasonable attendance in Monterey, theExecutive Committee prudently voted to increase the


25

Treasurer’s Reportmeeting reserves to $400,000. Were this modificationmade in 2006, the discretionary reserves would fall to$106,000. For the Journal of Rheology, proceedsfrom the licensing of library consortia continue toclimb (see under JORO revenue). As a result, theelectronic publishing venture, which started out withheavy expenses, is now showing a modest profit. Forthe Society in general, we are pleased to report that

the Vancouver meeting was finally closed in 2006with a small profit, after accounting for StudentTravel and Executive Committee Expenses. ThePortland Annual Meeting will be described at theAnnual Meeting in Salt Lake City, along with ageneral discussion of meeting accounting issues.

Respectfully submitted,Montgomery T. Shaw, Treasurer

suffer from a number of shortcomings. For example,it predicted that particles would migrate if thesuspension was sheared in a parallel plate device butnot in a cone and plate apparatus, whereasexperiments showed that the reverse was the case.Also, it could not account for the normal stresseswhich Gadala-Maria had measured some yearsearlier. Finally, it was far from clear how thetrajectory model could be extended beyond any butthe simplest unidirectional flows. In contrast, John &Nott’s suspension balance model is based on theprinciples of mechanics plus dimensional analysisand, as modified by Jeff Morris, not only avoids theshortcomings of the trajectory model referred toabove, but can also serve as a proper constitutiveequation for a large class of complicated, and evensome three-dimensional, flows. Consequently, it isthe suspension balance model which is currentlyused on a worldwide basis when studying therheology of concentrated suspensions.

John has received numerous international awards ofwhich the AIChE Professional Progress Award (’98)and his election to the National Academy ofEngineering (’99) particularly stand out. In addition,he served as an Associate Editor of the Journal ofFluid Mechanics (’90-’04) and became the Editor ofthe Journal of Rheology in July ’05. And last but notleast, he has proven to be an outstanding mentor ofPhD students some of whom, e.g. Don Koch atCornell, Ron Phillips at the Univ of California atDavis, Louis Durlofsky at Stanford, RogerBonnecaze at the Univ of Texas at Austin, and JeffMorris at the Levich Institute CCNY, are rapidlydeveloping international reputations of their own. Amore stellar list of accomplishments would bedifficult to imagine.

He has concurrently held an AdjunctProfessorship in Physics and Applied Science at theCollege of William and Mary. The author of over 190publications, he received his B.S., M.S. and Ph.D. inphysics from MIT. He is a Fellow of the AmericanPhysical Society.

Outgoing CEO and Executive Director Marc Brodskyserved AIP for thirteen and a half years. During histenure, Brodsky oversaw dramatic changes in AIPpublishing, as nearly all processes were changed todeal with electronic publishing.

The fund honors Marc H. Brodsky*s distinguishedcareer as AIP*s Executive Director and CEO from1993-2007, as well as his innovative work as anindustrial physicist.

"In 1991 a fire at my company destroyed our records,and in recreating them, we conducted several oralhistories of key personnel," says Julian A. Brodsky,co-founder, Director and Vice Chairman of ComcastCorporation. Julian, Marc's brother, is one of the leadcontributors to the fund.

"Recognizing Marc through this fund is veryappropriate because of his stellar reputation in theindustrial physics world as well as his work at AIP,"he says. "The fund honors both aspects of Marc*scareer."

The fund was established on March 29, 2007 by leadgifts from the Lois and Julian Brodsky Family, Johnand Elizabeth Armstrong, and from many others.Currently, over $84,000 has been pledged to theFund, which will remain open over the next fouryears for future contributions.
