Principal Investigator

Dr. Zee joined the biostatistics faculty at the University of Pennsylvania and the Children’s Hospital of Philadelphia (CHOP) Research Institute in 2020. She completed graduate training at the University of Pennsylvania and previously worked as a Research Scientist at Arbor Research Collaborative for Health in Ann Arbor, Michigan. Dr. Zee is a co-principal investigator on an NIH/NIDDK-funded study on computational pathology for proteinuric glomerulopathies, which uses computational approaches to identify new imaging markers of clinical outcomes. She is also principal investigator of a NIH/NIDDK-funded P50 project to develop marginal structural models for recurrent event outcomes to estimate causal effects of time-varying treatments. She has experience with data coordinating centers, including serving in her current role as a co-investigator for the Data Analysis and Coordinating Center for the Nephrotic Syndrome Study Network (NEPTUNE). Dr. Zee is a Planning Committee Member of the ENAR Fostering Diversity in Biostatistics Workshop, Co-Chair of the NEPTUNE/CureGN Career Enhancement Program, and Editorial Board Member of the journal Glomerular Diseases.

Biostatistician Research Analyst

Jane Liu joined Dr. Zee’s lab and the Children’s Hospital of Philadelphia (CHOP) Research Institute in 2022, providing analytic support to research projects in Dr. Zee’s lab. Prior to this, she worked as a research analyst at Arbor Research Collaborative for Health in Ann Arbor, Michigan.  Ms. Liu has coauthored on over 10 manuscripts, including several as lead author and most as lead analyst, published in peer-reviewed journals, and has contributed to abstracts presented at national and international scientific meetings. She has experience with a variety of analysis methods such as survival analysis, longitudinal analysis, machine learning, and simulations. Ms. Liu received her Bachelor of Medicine from Central South University in China in 2012, and Master in Public Health from Washington University in St. Louis in 2014. 

Biostatistician Research Analyst

Tran Bourgeois joined Dr. Zee’s lab and the Children’s Hospital of Philadelphia (CHOP) Research Institute in 2024, providing analytic support to research projects in Dr. Zee’s lab, including many collaborative clinical research projects in pediatric nephrology. Prior to this, she worked as a biostatistician at Nationwide Children's Hospital and Corevitas. Ms. Bourgeois has experience with a variety of analysis methods such as survival analysis and longitudinal analysis and pediatric datasets including PHIS. Ms. Bourgeois received her Bachelor of Science in Biochemistry and Master's of Public Health in Epidemiology and Biostatistics from The Ohio State University. 

MS Biostatistics Student

Shalini Ramachandra (she/her) is a fourth-year Biostatistics PhD student at the University of Pennsylvania. She joined the Zee Lab for her Biostatistics MS thesis work in 2023-2024 to understand variability in creatinine generation among patients with glomerular disease and continues to collaborate on several clinical research projects in nephropathology and glomerular disease. Her dissertation work focuses on causal inference methods for recurrent event models, under the guidance of Dr. Douglas Schaubel and Dr. Eric Tchetgen Tchetgen. Previously, Shalini obtained her Bachelor of Science in Mathematical Statistics and Bachelor of Science in Public Health at American University in Washington, DC. During this time, she was involved in two mathematics/statistics Research Experience for Undergraduate (REU) programs, an NIH internship at the NHLBI’s Office of Biostatistics Research, and an on-campus Nutritional Neuroscience lab as their student statistician.

MS Biostatistics Student

Meghan Gerety is a third-year Biostatistics PhD student at the University of Pennsylvania. She joined the Zee lab to work on her MS in Biostatistics thesis in 2024-2025, which focuses on using observational data to make causal inferences about the effect of different membranous nephropathy treatments on long-term patient outcomes. The project employed target trial emulation methods and investigated the use of these methods in the presence of a small sample size. Her dissertation work focuses on development of target trial emulation methods, under the guidance of Dr. Nick Seewald. Before coming to Penn, Meghan graduated from the University of Virginia, where she also conducted research in maternal and child health and analyzed single-cell RNA sequencing data for a biology lab. She has additionally worked with NIEHS and MaineHealth Institute for Research. Outside of biostatistics research, Meghan’s interests include running and improving her amateur cooking skills!
