OutlineOutline
• A review of research areas appearing in journals related to the physical sciences and engineering – chemistry, chemical engineering,
manufacturing, industrial engineering, …
• A brief discussion of possible ways to develop an active research program
Review of Selected PublicationsReview of Selected Publications
• I reviewed titles of articles published in three popular journals related to statistical theory and applications in the physical sciences and engineering:
Journal of Quality Technology (JQT) Technometrics (Techno) Quality Engineering (QE)
Review of Selected PublicationsReview of Selected Publications
Time Period: 2003 to 2008 5+ years
Number of Articles: 635
JQT 155 articles Technometrics 193 articles QE 287 articles
Review of Selected PublicationsReview of Selected Publications
Categorized into 5 areas of research:1. Statistical Quality Control / Statistical Process
Control (SQC/SPC)
2. Design of Experiments / Response Surface Methodology (DOE/RSM)
3. Reliability (REL)
4. Modeling (MOD)
5. Other (OTHER)
Review of Selected PublicationsReview of Selected Publications
• Each of the 5 areas had multiple research categories.
• Many articles were classified into 2 or 3 research categories.
• 842 research category classifications across the 635 articles.

The Future of SQC/SPC ?The Future of SQC/SPC ?
Product/Process Profile Analysis Multivariate Control Charts (Sampling
plans? Response vector contains both continuous and discrete response variables?)
New applications of SQC/SPC (To genomics / proteomics data? To microarray data? To ecological processes and spatial processes?)
The Future of RSM/DOE ?The Future of RSM/DOE ? “Space-filling” designs for irregularly-shaped
regions (applications of orthogonal arrays, Latin hypercubes, uniform designs ?)
Mixture designs with many components in highly-constrained regions (applications of orthogonal arrays, Latin hypercubes, uniform designs ?)
Restrictions on randomization, split-plotting (in mixture experiments, with categorical responses?)
Desirability functions + optimal design (How do we combine several design evaluation criteria?)
Genetic algorithms (Can we apply GAs to the problems above?)
The Future of Modeling?The Future of Modeling?
Generalized linear models + response surface methodology (Response optimization? Robust designs?)
Model and variable selection Information criteria (e.g. AIC)? Model averaging?
Bayesian methods?
Classification and Regression Trees ?
Some Thoughts on Developing an Active Some Thoughts on Developing an Active Research ProgramResearch Program
• Networking
• Working with other statisticians
• Working with other researchers who are not statisticians
NetworkingNetworking
• Attend conferences• Present research at conferences• Introduce yourself to other researchers• Do not be afraid to ask questions• Personal example: Dr. Greg Piepel, a
statistician at Pacific Northwest National Laboratories (PNNL), USA
• Result: I became Visiting Faculty at PNNL, submitted research for publication in JQT
NetworkingNetworking• Keep in contact with other researchers (For
example: former students)• Personal example: In 2005, I was invited by
Thammasat University to be a Visiting Faculty member because of a former PhD student from my university who now teaches in Thailand.
• Result: I have been a Visiting Faculty member for 4 summers, and I am involved in TU student research, received a Fulbright scholarship, attended conferences and visited other universities in Thailand, Thailand Statistician
Working with other statisticiansWorking with other statisticians
• Read abstracts of journal articles as often as possible so that you are aware of current research topics
• Be patient.• Personal Example: Nam-Ky Nguyen
(Hanoi, Vietnam) asked me to be co-author on research paper
• Result: Publication in JSPI (2008) and invitation to work on World Bank Problem in Vietnam
Working with other researchers Working with other researchers who are not statisticianswho are not statisticians
• Many researchers need statistical help (consulting, data analysis, summarizing results)
• Personal Example: I work with researchers in ecology and environmental science, biology, earth science, …
• Result: I have received money from their research grants and published in their journals: J. of Wildlife Management, J. of Range Management, Weed Science,…
Some ObservationsSome Observations
• I believe there is potential for collaborative research – within Thailand– between Thailand and other countries
• The problem is to determine what opportunities exist and then how to address them
• The solution begins with communication (primarily networking)
How well do you know your colleagues ?How well do you know your colleagues ?
• Do you know what your colleagues are interested in ?
• Do you know what their specialty areas are in statistics ?
• Do you know which colleagues are interested in collaborative research ?
Things to ConsiderThings to Consider
• Create a directory of statisticians who want to develop their research program
• Determine if they have any specific research areas of interest
• Determine if they have any specific research problems that require collaboration
(Conduct a survey ?)
Things to ConsiderThings to Consider
• Many U.S. universities have funded international programs that allow faculty to visit other countries for research
• Contact directors of these programs expressing interest in developing a relationship with your organization (e.g., exchange of faculty and students)
• Many international faculty would like to visit Thailand
