February-July 2016
Timothy Deming
Professor of Bioengineering and Professor of Chemistry and Biochemistry
University of California, Los Angeles
Hosted by Laboratoire de Chimie des Polymères Organiques, Université de Bordeaux
Henri Cramail (Director) and Sébastien Lecommandoux (Assistant Director)
Timothy J. Deming received a B.S. in Chemistry fom the University of California, Irvine in 1989, and graduated with a Ph.D. in Chemistry from the University of California, Berkeley, under Bruce Novak in 1993. After a NIH postdoctoral fellowship at the University of Massachusetts, Amherst with David Tirrell, he joined the faculty in the Materials Department at the University of California, Santa Barbara in 1995. Here he held a joint appointment in the Materials and Chemistry Departments where he was promoted to Associate Professor in 1999 and Full Professor in 2003. His appointment is now as Professor of Bioengineering and Professor of Chemistry and Biochemistry at the University of California Los Angeles. He served as the Chairman of the Bioengineering Department at UCLA from 2006 to 2011. He is a leader in the fields of polypeptide synthesis, self-assembly of block copolypeptides, and biological activity of polypeptides, for which he has received awards from the National Science Foundation, the Office of Naval Research, The Arnold and Mabel Beckman Foundation, the Alfred P. Sloan Foundation, the Camille and Henry Dreyfus Foundation, the Materials Research Society, and the IUPAC Macromolecular Division. He was recently named a Fellow of the American Institute of Medical and Biological Engineering.

William Weeks
Professor of Psychiatry and of Community and Family Medicine
Geisel School of Medicine, Dartmouth College
Hosted by Aix-Marseille School of Economics, Université d'Aix-Marseille
Bruno Ventelou, Professor at AMSE and Researcher with GREQAM
William B. Weeks, MD, PhD, MBA, is Professor of Psychiatry and of Community and Family Medicine at The Geisel School of Medicine at Dartmouth. There, he works at The Dartmouth Institute for Health Policy and Clinical Practice as a Senior Research Scientist, where he teaches in several masters programs and conducts research on health economics, healthcare value, physician incomes, the complementary and alternative medicine market, and geographic variation in health services utilization in France. He is also Chair, Clinical and Health Services Research Program, at the Palmer Center for Chiropractic Research at Palmer College of Chiropractic in Davenport Iowa. There, he works on how doctors of chiropractic and other complementary and alternative medicine providers supply healthcare services, and how their patients use such services. Dr. Weeks has published over 150 peer-reviewed manuscripts examining economic and business aspects of rural veterans’ health care services utilization and delivery, physicians’ return on educational investment, and health care delivery science, including patient safety, quality improvement, Accountable Care Organizations, complementary and alternative medicine, geographic variation, and healthcare value.

Inaugural Lecture:February 25th at noon at the Fondation Iméra in Marseille.
Subject: Geographic variation in hospitalization use in France
Geographic variation in use of healthcare services has been widely studied in the US, where excessive variation is considered evidence of healthcare system waste that could be reduced by policy interventions. In France, geographic variation in use of healthcare services has not been as widely studied. In this lecture, Dr. Weeks will provide results of his analysis of geographic variation in the use of hospitals for common elective surgical procedures and for ambulatory care sensitive conditions in France between 2009 – 2013. Trends in rates of admission, characteristics of admissions, use of for-profit and not-for-profit hospitals, and comparisons to rates of admission in the US will be explored.
