Isildinha M. Reis, Dr. Ph., Core Leader, Biostatistics Division, Research Associate Professor, Department of Epidemiology and Public Health

Dr. Reis joined the University of Miami and Sylvester Biostatistics in 1999 as Research Assistant Professor in the Department of Epidemiology and Public Health and was promoted to Research Associate Professor in 2006. Dr. Reis earned her Master’s degree in public health from the University of São Paulo and her DrPH in biostatistics from the University of California, Los Angeles. She has 20 years experience in statistics and statistical methodology, beginning with a pharmaceutical company in São Paulo, Brazil, followed by a faculty appointment in the School of Public Health at the University of São Paulo. Dr. Reis’s areas of special interest include survival analysis, repeated measures analysis, and statistical methods for planning and analyzing oncology clinical trials and clinical epidemiology studies. She is a member of Sylvester’s Protocol Review Committee (PRC) and an alternate voting member of the Data and Safety Monitoring Committee (DSMC). Dr. Reis is the Biostatistics-designated statistician for both the Viral Oncology and the Molecular Therapeutics research programs as well as the breast cancer site disease group. Dr. Reis regularly teaches a one-semester graduate course in survival analysis.

Tulay Koru-Sengul, Ph.D., Assistant Professor

Dr. Koru-Sengul is an experienced statistician and clinical trial methodologist who joined the University of Miami and Sylvester Biostatistics in 2008 with appointment as an Assistant Professor in the Department of Epidemiology and Public Health. Dr. Koru-Sengul earned her Master’s degree in biostatistics from Johns Hopkins University, and both Master’s and Doctoral degrees in statistics from University of Pittsburgh. She held faculty appointments at the State University of New York at Buffalo, University of Saskatchewan and McMaster University in Canada. Along with her faculty appointments, Dr. Koru-Sengul was the director of the Statistical Consulting Laboratory in the Department of Biostatistics at the State University of New York at Buffalo, a Research Scientist at Saskatchewan Health Quality Council, and a Faculty Biostatistician in the Clinical Trials Methodology Group at Ontario Clinical Oncology Group in Canada. Her research areas include biostatistics, design and analysis of clinical trials, statistical genetics, longitudinal data analysis, analysis of repeated measurement data, missing data analysis, analysis of longitudinal responses in the presence of missing data, joint modeling of longitudinal and survival data and statistical methods for high dimensional medical data. Her primary biostatistical research interests lie in the development and application of statistical methods for biological responses that vary in time and occasion. Her publications and conference presentations include her methodological work in statistics as well as her collaborative work in various fields in medicine. Dr. Koru-Sengul is an affiliate of Sylvester’s Cancer Epidemiology and Prevention (CEP) program, and a member of Sylvester’s Protocol Review Committee (PRC) and Sylvester’s Data and Safety Monitoring Committee (DSMC).
