About Me

I’m a PhD Student in Biostatistics at University of Arizona. I got my ScM in Biostatistics from Johns Hopkins University. My current research focus on developing statistical models for meta-analysis. Under the guidance of Dr. Lifeng Lin and Dr. Jessie Tong, I am concentrating on IPD meta-regression methods and addressing publication bias. Additionally, my work also involves the epidemiologic analysis of musculoskeletal diseases, under the guidance of Dr. Guoqi Cai.

Outside of academia, I’m a dead hard fan of Juventus and Park Hyatt.
