J. Richard Landis, PhD
Professor of Biostatistics
Dr. Landis serves as director of the biostatistics unit within the Center for Clinical Epidemiology and Biostatistics (CCEB) and as faculty co-director of the Clinical Research Computing Unit (CRCU), a designated core research facility providing clinical research informatics (CRI) collaboration and services for clinical and translational research investigators at Penn.
For more than 40 years, he has been actively involved in collaborative biomedical research and in the development and evaluation of methods for the analysis of categorical data. His methodological research interests are in the analysis of categorical data, particularly statistical methods for repeated measurement and longitudinal categorical data, clinical trials, epidemiological studies, complex sample surveys and applications to cardiovascular, ophthalmology, respiratory, psychiatric, renal and urological research.
Prior to assuming his current position in 1997, Dr. Landis was a professor of biostatistics at the University of Michigan School of Public Health, where he served on the faculty for 13 years (1975-1988). In 1988, he founded the Center for Biostatistics and Epidemiology at the M.S. Hershey Medical Center of the Pennsylvania State University, and served as its director for nine years before his relocation to Penn. He holds a secondary appointment as professor of statistics in Penn's Wharton School.
Dr. Landis is director of the research methods core and co-investigator in the informatics core in Penn’s Clinical and Translational Science Award Hub (2016-21). He serves as principal investigator (PI) of the data coordinating center (DCC) for the National Institute of Diabetes and Digestive and Kidney Diseases' (NIDDK's) Multidisciplinary Approach to Pelvic Pain Research Network (2008-19), having previously served as PI of the DCCs for NIDDK’s Urologic Pelvic Pain Collaborative Research Networks (CPCRN, ICCTG, CPCRN-2, ICCRN) that conducted nine randomized controlled trials (1998-2008). Within renal research, he also serves as co-principal investigator (with Dr. Feldman) of the scientific and data coordinating center for NIDDK’s Chronic Renal Insufficiency Cohort (CRIC) Research Network (2001-18), multiple principal investigator (with Dr. Dember) for NIDDK’s Data Coordinating Center for Hemodialysis Pilot Studies Consortium (2013-18), and co-investigator (with Dr. Dember) for the Pragmatic Trials in Maintenance Hemodialysis (2012-17).
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).
