David Afshartous Ph.D. is a Research Associate Professor of Biostatistics who came to Vanderbilt in September 2010. He received his PhD in Mathematics (Statistics) from U.C.LA. in 1997, having previously trained at M.I.T. (mathematics and political science). His methodological research interests include longitudinal data analysis, mixed models, classification, and clinical trials. David previously worked as a biostatistician in the Division of Clinical Pharmacology at the University of Miami. His background also includes five years as a systems engineer at Lucent Technologies, Bell Labs. David is currently dedicating approximately 25% of his effort to Anesthesiology.
