Prior to joining ZLab, Jinyu was an undergraduate student at the University of Science and Technology of China (USTC). He was fascinated by modern atomic physics technologies and conducted research on atom trap trace analysis (ATTA) with calcium atoms. He also gained research experience with nitrogen-vacancy (NV) color centers in diamond. Now as a PhD student at Columbia, Jinyu is continuing his journey of exploring the secrets of nature. He is currently working on laser cooling and trapping of CaH molecules. He is having a great time, and loves anything to do with physics!
