Before joining Cedars-Sinai, Sungjin was a senior biostatistician providing statistical expertise in study design, data analysis, and proposal/manuscript preparation for clinical and pre-clinical investigators at the Winship Cancer Institute of Emory University in Atlanta. She has many years of collaborative experience in various cancer researches, biomarker studies, and health service researches. Her experiences include survival analysis, longitudinal data analysis, receiver operating characteristic (ROC) analysis, propensity score analysis, meta-analysis, joinpoint regression analysis, and early phase clinical trials designs.

Heidi Gransar, MS, CCRP, is a research biostatistician in the Division of Cardiac Imaging and Nuclear Cardiology at the S. Mark Taper Foundation Imaging Center, Department of Imaging. She received her master's in biostatistics from UCLA in 2001 and has been at Cedars-Sinai since 2000. She does statistical analysis, consulting, assists in study design, and also database management for researchers in her department. She occasionally gives lectures to fellows and student interns on statistical topics. Gransar mainly uses STATA and SAS.

James Mirocha, MS, is a senior biostatistician in the Research Institute and the Samuel Oschin Comprehensive Cancer Institute. He received his MS in mathematics from the University of Minnesota in 1975. He finished PhD coursework and qualifying exams in statistics and quantitative methods in the Graduate School of Education and Information Studies at UCLA in 2001 (ABD). Mirocha has extensive teaching experience in mathematics and statistics at the high school, community college and university levels. He has been at Cedars-Sinai since 1999. Mirocha serves on the Scientific Advisory Committee in the Clinical and Translational Research Center and on the Institutional Review Board. His main interests are in the areas of power analysis, propensity modeling, mixed and longitudinal modeling, and survival analysis. Ongoing projects are with Cardiothoracic Surgery, Trauma Research, Cardiology, Psychiatry, Pathology, Transplant and the Cancer Center.

Michael Luu, MPH, is a research biostatistician at the Samuel Oschin Comprehensive Cancer Institute. Luu received his master’s in public health with an emphasis in biostatistics and epidemiology at the University of Southern California in 2015. He is a proficient R programmer who was also trained in SAS, STATA and SPSS. His experience involves survival analysis, predictive modeling and data visualizations, among other areas. Current and past projects involve analysis of large national inpatient databases such as the National Cancer Database, SEER-Medicare from the National Cancer Institute, Healthcare Cost and Utilization Project, California’s Office of Statewide Health Planning and Development and Pediatrics Health Information Systems. Before joining Cedars-Sinai in 2016, he served as a biostatistician at Children’s Hospital Los Angeles for the Division of Neonatology and Department of Anesthesia Critical Care Medicine.
