Jiansong was born and raised in Changsha, Hunan, China. He received his Ph.D. in Biomedical Engineering and Biotechnology from the University of Massachusetts Lowell. His doctoral research focused on engineering Yarrowia lipolytica for the production of omega-3 fatty acids from waste cooking oil. In the Prof. Stephanopoulos Lab at MIT, his research focuses on improving carotenoid production and the long-term stability of engineered Y. lipolytica. His work combines metabolic engineering and bioprocess development to advance sustainable microbial production of valuable compounds.
