Winter 2002 Vol. 2

Greetings from the Department Head,
Dr. Geoffrey Vining

Happy New Year! A lot has been going on in the Department this year! Most of it has been pretty exciting.

Eric Smith and Geoff Vining were named Fellows of the American Statistical Association. We now have five Fellows among the active faculty plus four more Fellows among the emeritus faculty. Very few departments of our size have so many Fellows, which is a true testimonial about the strength of our department.

Corporate Partners

Bill Woodall winning the Brumbaugh Award from the American Society for Quality was another important highlight for the department. This prestigious award is given annually to recognize the paper published in an ASQ journal which has made the greatest contribution to the development of industrial applications of quality control.

Much of the Department's energy has been focused on our VIGRE grant submission. VIGRE (Vertical Integration of Graduate and Research Education) is a major initiative from the Mathematical Sciences Division of the National Science Foundation designed to revamp how mathematics and statistics departments do business. We are considering a lot of new ideas for getting undergraduates interested in research, for recruiting more students into our Ph.D. program, and for mentoring these students once they are here. We are also looking at how to improve our curriculum. Several exciting ideas include one-hour special topics courses and "tracks," such as industrial, environmental, econometric, and bioinformatics. Jeff Birch has been doing an excellent job leading and coordinating our efforts.

This fall, we held our initial Corporate Partners Conference. Golde Holtzman put a great deal of work into this program, and it was quite successful. Our Corporate Partners provide crucial financial support that allows the department to make enhanced graduate assistantship offers. In addition, the Corporate Partners provide advice and counsel to the department.

Last summer, the Department hosted the SPES-IMS Spring Research Conference at the Hotel Roanoke. Christine Anderson-Cook did a great job as the local organizing chair.

This fall, the department also hosted the Business Meeting for the Southern Regional Council for Statistics, the old SREB. Representatives from the major statistics program across the South came to exchange ideas. Blacksburg proved to be a big hit with this group.

This spring, the Department is hosting a special conference in honor of Ray Myers. You can find details off our web page. Please plan to attend. We would love to see you again here in Blacksburg.

Unfortunately, not every thing is rosy here in Blacksburg. The recession combined with September 11 has taken a toll on the Commonwealth's economy. All of the Universities in Virgina, including Virginia Tech, face a significant callback of funds. Everyone expects the situation to be temporary. Nonetheless, it is somewhat painful.

We hope that all of you are doing well. If you are ever in the area, please drop by and see us. It is always good to visit with our alumni and friends. As well, we encourage you to take advantage of the Alumni News section, which we hope will make keeping up with some of your peers possible. We also enjoy hearing your news and staying in touch.

Geoff

New Faculty

The Department of Statistics was delighted to welcome 3 new faculty members to our department in the Fall of 2001:

Samantha Bates joined us after graduating from the Department of Statistics with both her Masters of Sciences and Ph.D. from the University of Washington. Her areas of research include Bayesian inference, Markov chain Monte Carlo methods, deterministic models, model validation and environmental statistics.
She won the Best Paper in Risk Assessment and shared the Best Student Presentation award, at the 2001 meeting of The International Environmetrics Society, and a Student Paper award at the 1998 Annual Meeting of the Society of Risk Analysis. Sam did her undergraduate work at the University of Auckland, New Zealand.
Dan Spitzner joined the department from the University of North Carolina at Chapel Hill. In 1994, Dan graduated with both a Masters and Bachelor of Sciences from the Virginia Tech Department of Statistics. His dissertation research was in the area of shrinkage estimation under the direction of R.L. Smith. His interests are in linear models, functional data analysis, biased estimation methods, decision theory, and high-dimensional inference. He has published applied research in the areas of particulate matter epidemiology, and the physiology of human tactile perception. He is currently teaching Statistics in Research.
Philippe Barbe joined our department from the Centre National de la Recherche Scientifique (CNRS) in France. He obtained his Diploma of Statistician from Ecole Nationale de las Statistique et de l'Administration Economique in Paris in 1998. He has been a visiting professor in recent years at Yale University, Georgia Institute of Technology and Universite' Laval. He has published two books "Cours de Probabilite pour la Licence" and "The Weighted Bootstrap". His areas of research interest are currently an intersection of statistics, probability, asymptotic analysis, and differential geometry.

    The Department of Statistics Corporate Partners Program was conceived last year with the goal of solidifying and formalizing the strong relationships that have flourished between industry and our department over the past 50 years. A most successful step toward that goal was taken early in November--Thursday the 8th through Saturday the 10th --when our faculty and graduate students hosted the first annual Corporate Partners Program Conference. Lodging, meals, and local transportation were provided for two representatives of each corporate partner so that we could make the most of our weekend together. The conference featured:

    Representatives from Eli Lilly Pharmaceuticals, Minitab, Inc., DuPont, and General Electric participated. Matt Rotelli and Janet Bernard came from Indianapolis on behalf of Eli Lilly, Gwen Stimely came from University Park, Pennsylvania and Jennifer Roan came from the Research Triangle of North Carolina on behalf of Minitab, Inc. Bill Letsinger came from Delaware on behalf of DuPont, while Angie Neff Patterson, who taught here last fall as a visiting professor, represented General Electric.
    The conference started of Thursday evening with a wine-and-cheese social at the home of Geoff Vining. Friday morning some of the partners met with the departmental Advisory Committee, while others began a series of one-on-one interviews with masters and doctoral candidates that continued through Saturday afternoon.


    A research colloquium convened Friday afternoon chaired by Professor Bill Woodall. Ina Hoeschele (joint professor of statistics and genetics) , and five graduate students--Ed Boone, Seth Clark, Paula Johnson, Rachelle Koudelik, Ilya Lipkovitch, and Megan Waterman--presented brief overviews of their current research projects. The activities culminated Friday evening in a spirited dinner-party attended by nearly the entire department at Anchy's.

    The general consensus was that the benefits of the conference were well worth the hard work of all who participated. By the end of the evening Friday, many new relationships had formed among the partners, graduate students and faculty.

    Grant News

    The faculty continues to be active in the pursuit of external funding. These efforts are likely to increase in the future. Recent awards include a $19,016 grant of the Virginia Water Resource Research Center to Eric P. Smith and Keying Ye. The same investigators are also currently working on a $266,388 grant from the U.S. EPA entitled "Assessing the Effects of Multiple Stressors in Environmental Monitoring Programs". Keying Ye was awarded a Virginia Tech ASPIRES grant in the amount of $41,852 as co-principal investigator with Dr. Shannon Jarrott of the Department of Human Development. William H. Woodall is completing research on a $83,932 NSF grant entitled "Collaborative Research: Multivariate Methods for On-Line and Off-Line Quality Control and Improvement".

    "From Consultant to Effective Leader"

    This conference is designed to enhance the effectiveness of statisticians in business and industry, particularly as it relates to exhibiting leadership. The goal is to help statisticians transition from being viewed as passive consultants to being viewed as proactive leaders within their organizations. In preparation for this conference, several senior business leaders, CEOs and other executives were interviewed to obtain their insights into how statisticians can have more impact. These insights will be shared and discussed at the conference.
