For nearly thirty years, Dr. Landis has been actively involved in collaborative biomedical research, and the development and evaluation of methods for the analysis of categorical data. He is PI of two clinical research networks - the Chronic Prostatitis Clinical Research Network (CPCRN) and the Interstitial Cystitis Clinical Research Network (ICCRN), coordinated within a unifying framework as the Urological Pelvic Pain Clinical Research Network (UPPCRN). Dr. Landis also currently serves as Co-PI for the NIDDK's adult Chronic Renal Insufficiency Cohort (CRIC) Research Network , with Harold I. Feldman, MD as PI. Dr. Landis also directs a three-year NIH Broad Agency Announcement (BAA) Roadmap contract focusing on "Re-Engineering the Clinical Research Enterprise: Feasibility of Integrating and Expanding Clinical Research Networks."
Dr. Landis has co-authored more than 150 articles in the peer-reviewed scientific literature. His publications are in the areas of statistical methods for repeated measurement and longitudinal categorical data, epidemiological studies, complex sample surveys and applications to cardiovascular, ophthalmology, respiratory, psychiatric, renal and urological research. He served on the Epidemiology and Disease Control Study Section for NIH from 1984-88 and again for a second term from 1993-97, serving as Chair during 1996-97.
Dr. Landis's honors include Fulbright Senior Scholar (University of Newcastle, Australia, 1981-82), Fellow of the American Statistical Association, elected member of the International Statistical Institute, recipient of the Mortimer Spiegelman Gold Medal Award (1984) and recipient of an Environmental Protection Agency Scientific and Technical Achievement Award (1987).
