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 principal investigator on an NIH/NIDDK-funded study on comparative treatment effectiveness and surrogate endpoint evaluation in membranous nephropathy (MN) and 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 is also lead biostatistician on the International Society of Glomerular Disease's PARASOL-MN project. 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 Excellence in Biostatistics Workshop, Co-Chair of the NEPTUNE/CureGN Career Enhancement Program, Editorial Board Member of the journal Glomerular Diseases, and Statistical Reviewer for the American Society of Nephrology (ASN) Journal Portfolio (JASN, CJASN, Kidney360). She has been recognized as a Fellow of the American Society of Nephrology (FASN) since 2025.

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

Xiaohan Liu is a second-year Biostatistics PhD student at the University of Pennsylvania. She joins the Zee Lab for her Biostatistics MS thesis work in 2025-2026 focused on evaluating proteinuria relapse as a mediator of treatment effects on disease progression for individuals with membranous nephropathy. Previously, Xiaohan obtained her Bachelor of Science in Statistics and Data Science at Carnegie Mellon University in Pittsburgh, PA. During this time, she conducted research in experimental linguistics, collaborated on statistical consulting projects, served as a teaching assistant, and participated in a Summer Institute in Biostatistics (SIBS) program solidifying her interest in pursuing graduate education in biostatistics. 

MS Biostatistics Student

Daniel Goldblatt is a second-year Biostatistics PhD student at the University of Pennsylvania. He joined the Zee Lab in summer 2026 for his Biostatistics MS thesis, which aims to determine the optimal treatment regime for individuals with membranous nephropathy based on patient characteristics. Daniel earned his Bachelor of Arts from Colby College in Waterville, ME, in May 2025, majoring in Mathematical Sciences with minors in Data Science and Physics. He was introduced to biostatistics through the University of Michigan’s Big Data Summer Institute in summer 2023. Inspired by that experience, he interned at the National Institute of Environmental Health Sciences (NIEHS) the following summer, where he investigated the association between propensity for pregnancy loss and subsequent gestational diabetes and type 2 diabetes. That work ultimately led him to pursue a PhD in biostatistics.  

PhD Biostatistics Lab Rotation Student

Grace Wang is a second-year Biostatistics PhD student at the University of Pennsylvania. She joins the Zee Lab for her 2026 summer rotation, focusing on the evaluation of mediation methods in the context of survival outcomes and longitudinal mediators to evaluate surrogate endpoints; in particular, the role of PLA2R-Ab as a mediator of disease progression in membranous nephropathy. Previously, Grace received her Bachelor of Science in Data Science and Health Science at Northeastern University. During this time, she conducted research at the Fishell Lab analyzing single-cell RNA and ATAC sequencing data to support cortical interneuron research and worked at UCB developing and training a neural network model to predict peptide biological function.    

Undergraduate Student Intern

Anna Ramesh is a senior Biological Sciences major at Drexel University in the BS/MD Early Assurance Program. She previously conducted research in the Reginato Lab at the Drexel University College of Medicine, investigating aberrant lipid metabolism reprogramming in triple-negative breast cancer brain metastases, and in the Amaravadi Lab at the Perelman School of Medicine, exploring how targeting glycosphingolipid synthesis can enhance antitumor immune responses in melanoma. She joins the Zee Lab to lead exploratory data analysis of computational pathology datasets in glomerular diseases, integrating clinical, demographic, genetic, and pathomic data to identify disease subgroups and evaluate associations with biomarkers. Concurrently, Anna conducts research with Dr. Srijan Tandukar and Dr. Kiran Goli on kidney transplantation outcomes and transitions to general nephrology care, analyzing follow-up and patient outcomes. Her experiences across oncology and nephrology research, along with clinical exposure, have shaped her interest in translational research that bridges scientific discovery and patient care.
