Yuzi Zhang
Assistant Professor
Biostatistics
“In this data-rich world, with the increasing ability to acquire data from diverse sources, my work as a biostatistician motivates me to develop statistical methods for real-world challenges. I am excited to contribute to the shared goal of advancing public health.””
Biography
Dr. Zhang's research primarily focuses on two areas: developing statistical methods for environmental epidemiological studies, particularly in assessing health effects of environmental exposures; and disease surveillance, with a specific focus on capture-recapture methods. She is also interested in mediation analysis with applications to metabolomics data.
