Yongjin Park is a graduate student researcher in Christopher Voigt’s lab at the MIT synthetic biology center (SBC). He decided to pursue a Ph.D. after being intrigued by the concept of genetic circuits, which harness biological regulatory mechanisms to sophisticatedly control cellular behaviors. His research is focused on designing and implementing genetic circuits on the bacterial genome to improve the stability of genetic circuits without using antibiotics. By improving the stability, he seeks to apply genetic circuits to diverse biotechnology applications. Prior to pursuing a Ph.D. at MIT department of biological engineering, he graduated from Korea Advanced Institute of Science and Technology (KAIST) with a B.S. in Chemical and Biomolecular Engineering.
