Isildinha M. Reis, Dr. Ph., Research Associate Professor

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 more than 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 the Data and Safety Monitoring Committee (DSMC). Dr. Reis is an affiliate of the Biobehavioral Oncology and Cancer Epidemiology (BOCE) program and the BCR-designated statistician for both the Viral Oncology (VO) and the Molecular Targets and Developmental Therapeutics (MTDT) research programs as well as the breast cancer SDG. Dr. Reis regularly teaches a one-semester graduate course in survival analysis.

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

Dr. Koru-Sengul joined the University of Miami and Sylvester Biostatistics in 2008 with appointment as 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.
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 primary research interests lie in the development and application of statistical methods for biological responses that vary in time and occasion, with particular emphasis on the analysis of longitudinal responses in the presence of missing data and joint modeling of longitudinal responses and event process. Dr. Koru-Sengul has been appointed a member of Sylvester’s Protocol Review Committee (PRC).

Deukwoo Kwon, Ph.D., Associate Scientist

Dr. Kwon earned a Ph.D. in statistics from Texas A&M University in 2005 and worked at the National Cancer Institute for six years. Dr. Kwon worked on radiation exposure assessment, uncertainty analysis, and measurement error models in dose-response relation at NCI. He joined Sylvester Biostatistics Core in October 2011. His research interests are high-dimensional data analysis, genetic association study, proteomics data analysis, advanced Bayesian computational techniques, non-inferiority tests, and joint modeling of longitudinal and time-to-event data.

Wei Zhao, M.D., M.S., Senior Research Associate 3

Ms. Zhao, who holds a MD degree from Wuhan Medical School as well as master’s degrees in both computer information systems and in applied statistics from the University of Miami, joined Sylvester Biostatistics in 2008.
