Study Design & Data Analysis Center



The center is comprised of faculty and graduate students from Epidemiology and Biostatistics. Experts from the College of Public Health will also provide assistance to the center.

Henian Chen, MD, PhD, Professor of Biostatistics

Dr. Chen joined the USF faculty on August 29, 2011. He is a professor of biostatistics in the Department of Epidemiology and Biostatistics and the director of the biostatistics PhD program. Prior to coming to USF, Dr. Chen was a senior biostatistician and research scientist in the Department of Epidemiology at the New York State Psychiatric Institute (1999-2010), adjunct assistant professor in the Department of Epidemiology, Mailman School of Public Health at Columbia University (2002-2005), senior core faculty and senior biostatistician in the Department of Biostatistics at the New York State Psychiatric Institute (2006-2010), assistant professor in the Department of Psychiatry, College of Physicians and Surgeons at Columbia University (2006-2010), and senior biostatistician and associate professor at Stony Brook University School of Medicine and Winthrop University Hospital (2010-2011). Prior to his immigration to the United States in 1998, Dr. Chen was the founding chair (1994-1998) of the Biostatistics Department at Southern Medical University in China. His research interests include clinical trials, missing data, longitudinal data analyses and causal inference, epidemiological methods and psychiatric epidemiology. He has been a co-investigator on the Children in the Community (CIC) study since 1999, which is a longitudinal study followed from 1975 with three generations (mothers, offspring and grandchildren). Dr. Chen has published more than 110 research articles. He has worked for more than 100 NIH grant proposals. Dr. Chen is a biostatistical reviewer for NIH clinical trial applications. His collaborations with investigators at Columbia University have resulted in more than 10 NIH R01 funded grants. Dr. Chen has been involved in more than 45 clinical trials and taught Design and Analysis of Clinical Trials, Biostatistics I & II and Epidemiological Methods courses at Columbia University and USF. Dr. Chen serves as the director of the Study Design and Data Analysis Center.
Wei Wang, Ph.D.

Wei Wang, PhD, Associate Professor of Biostatistics

Dr. Wang has worked at the College of Public Health as a faculty member since 2008. As an associate professor in the Department of Epidemiology and Biostatistics, Dr. Wang has served as the lead statistician in more than 20 federally funded studies and trials focusing on evaluating interventions and treatment using clinical trials. He has also published more than 50 peer-reviewed manuscripts in top journals disseminating the findings from these studies. He has also supervised more than 20 doctoral students and many more MPH/MSPH students. His expertise is on design and evaluation of clinical trials. Some of the methodologies he specializes in include integrated data analysis, multi-level modeling including linear and generalized linear mixed-effects models, structural equation models, mediation analysis and growth curve models.
Kevin E. Kip, PhD, FAHA

Kevin E. Kip, PhD, FAHA

Kevin E. Kip, PhD, FAHA is a tenured Distinguished Health Professor, epidemiologist, and biostatistician with 18 years of experience on U.S. Federal, Department of Defense, and industry-funded studies. His background is interdisciplinary with more than 170 peer-reviewed publications. With multi-million dollar funding from the U.S. Department of Defense, he established the Research to Improve Emotional Health/Quality of Life of Service Members with Disabilities, (RESTORE LIVES) Center at the University of South Florida. Through this Center, he is the leading researcher worldwide in the study of Accelerated Resolution Therapy (ART), an emerging, brief, and evidence-based method of psychotherapy for treatment of post-traumatic stress disorder (PTSD) and related comorbidities. Dr. Kip is previous Principal Investigator of the National Heart, Lung, and Blood Institute (NHLBI) Dynamic Registry of Percutaneous Coronary Intervention (PCI) which enrolled approximately 10,000 patients. He was a member of the Institute of Medicine (IOM) - Committee to Review the Health Effects in Vietnam Veterans of Exposure to Herbicides. Dr. Kip is current chair of the Data Safety and Monitoring Board (DSMB) for the NIDDK-funded Look AHEAD (Action for Health in Diabetes) multicenter trial, and is a frequent grant reviewer for the National Institutes of Health (NIH).
Yangxin Huang, Ph.D.

Yangxin Huang, PhD, Professor of Biostatistics

Dr. Yangxin Huang joined the USF as faculty member in 2005. He is tenured full professor of Biostatistics at the College of Public Health. Prior to USF, Dr. Huang was postdoctoral at Harvard School of Public Health in 2001-2003, and was assistant professor at University of Rochester in 2003-2005. He has published more than 120 articles in peer-reviewed statistical and scientific journals since 2005. As PI, Co-PI or Co-I, Dr. Huang had and have been working on a number of funded extramural projects from the various sources including NIH, NSF and NSA in supporting his research activities and collaboration, and is a grant reviewer for the NIH and NSF. He has also directed more than 6 PhD graduates as major professor and supervised more than 40 doctoral and MPH/MSPH students. Dr. Huang is experienced biostatistical collaborator in various funded and unfunded projects, grant proposals, manuscript preparation to conduct study design and protocol development. He also has expertise in managing data collection, statistical analysis and interpretation and presentation of analysis results, and providing general critique to grant proposal evaluation and critical review of manuscript to medical, public health and other scientific researchers. Dr. Huang’s research interests and interdisciplinary collaboration expertise are Bayesian statistics and MCMC-based algorithms, joint modeling for longitudinal and survival data, mixed-effects (multi-level) models for longitudinal data, Bayesian-frequentist hybrid approach for longitudinal data, change-point modeling for longitudinal data, quantile regression-based mixed-effects modeling, and missing, measurement error and zero-inflated data analysis as well as statistical applications in HIV/AIDS, diabetes, infectious diseases, cancer and neurology etc.
