Ning Chin

Ning Chin

Ning is pursuing her PhD in Integrative Pathobiology, focusing on microbiome and transcriptomic changes during rhesus cytomegalovirus infection and vaccination. Previously, she got her B.S. in Microbiology from the University of Oklahoma, Norman, and then M.S. in Forensic Science from UC Davis. During the SARS-CoV-2 pandemic, she is involved in Good Manufacturing Practice (GMP) work to manufacture and purify an adenovirus-based SARS-CoV-2 vaccine developed in the lab, which further affirms her determination of improving human health by hijacking microbial machinery. She is a mahjong enthusiast who teaches all her friends how to read Chinese characters so they can play with her.
