She has her bachelor’s degree in Medicine and a bachelor’s degree in Economics from Peking University. Gigi joined CTEU in 2020 and is mentored by Dr. Mingyang Song. Her research interests focus on identifying dietary, genetic, and biomedical determinants of cancers and cardiometabolic diseases, as well as integrating state-of-the-art techniques (e.g. GWAS, metabolomic, microbiome) into large cohort studies to better understand the etiology and causal pathways.
Daniel Kim
Daniel Kim is a medical school student at Harvard Medical School in the Harvard-MIT Health Sciences and Technology MD program. He graduated from Cornell University with a B.S. in Biological Sciences and is jointly mentored by Dr. Andrew Chan and Dr. Long Nguyen. His research focuses on understanding the lifestyle and dietary factors that influence both gut microbiome composition and colorectal cancer risk.
Jennifer Kizza, BS, MSc
Jennifer is a medical school student at Harvard Medical School. She joined the CTEU in November 2021 as an NIH NRSA Predoctoral fellow, mentored by Dr. Hamed Khalili. Her research interests include the epidemiology of inflammatory bowel diseases, particularly to understand disease pathogenesis, create predictive models regarding disease course, likely personalized response to specific therapies, and evaluation of novel treatments. She has a bachelors in Neurobiology with a secondary in Global Health and Health Policy from Harvard College and a Master of Science in Global Health Science from the University of Oxford. Prior to starting medical school, she also served as a US Fulbright Student Researcher to Uganda.
Jennifer Le
Jennifer joined the Warner Lab as a COVID Corps Intern in July 2020, helping with a survey to examine the effects of the COVID-19 pandemic on breast cancer care. As she finishes her senior year at UMass Amherst with a major in Microbiology, her new project is looking at how the pandemic will be affecting the health of school staff and faculty in the Greater Boston Area.
Daniel Sikavi
​
Daniel Sikavi is an M.D. student at Harvard Medical School. His research interests include dietary and other environmental exposures that underlie gastrointestinal malignancies. He earned an A.B. in Ecology & Evolutionary Biology and a certificate in Global Health & Health Policy from Princeton University.
Yujia Lu, MS
​
Yujia is a PhD candidate in Cancer Epidemiology at Harvard University, where she also earned her Master of Science in Epidemiology. She joined CTEU in 2024 and is mentored by Dr. Mingyang Song and Dr. Andrew Chan. Her research aims to uncover cancer etiology and improve prognosis by investigating the synergistic effects and interplay between diet, body composition, gut microbiome, host metabolomics and genetics. She is also dedicated to developing clinically accessible evaluation tools and identifying novel microbial or metabolite-based signatures or biomarkers through machine learning techniques, contributing to cancer prevention and control.
Derek Chang
​
Derek Chang is a second-year master's student at the Harvard T.H. Chan School of Public Health studying epidemiology. He received his bachelor's degree in public health from the University of California, Irvine and joined Dr. Mingyang Song's lab in 2024. His research focus is on the risk factors of colorectal cancer risk.
