About Geng (Frank) Bai

Geng (Frank) Bai started as a Research Assistant Professor for Biological Systems Engineering in 2018. He previously served as a Postdoctoral Research Associate for the department from 2014-2018.

He is interested in advanced plant phenotyping in field and greenhouse environment and precision agriculture. Working with others within Biological Systems Engineering and across the university, he has published peer-review articles and presented his research achievements at professional conferences.

He grew up in Chengdu city, Sichuan province, China. Before joining BSE, he earned his Ph.D. in Environmental Science and Technology from Niigata University, Japan; his M.E. in Agricultural Soil and Water Engineering from China Agricultural University, China; and his B.E. in Hydraulic and Hydro-Power Engineering from China Agricultural University, China.
