His primary research interests are ocean biogeochemistry of carbon and nutrients, and geochemistry of radioactive elements in surface and ground waters. Recently, his research interests have been expanded in linking ocean science and sustainability.Minhan Dai earned his B.S. degree from Xiamen University, China in 1987 and his Ph.D. from Université Pierre & Marie Curie, France in 1995. After a Doherty Foundation Postdoctoral Fellowship at Woods Hole Oceanographic Institution (WHOI), he took a faculty position at Xiamen University in 1998.

He is a leading PI of a “973” project funded through the National Basic Research Program of China on “Carbon cycling in China Seas - budget, controls and ocean acidification” (CHOICE-C) which was renewed by the Ministry of Science and Technology (MOST) of China (2015-2019). He is also a leading PI of a newly funded NSFC major project “CARBON Fixation and Export in the oligotrophic ocean” (Carbon-FE) (2019-2023). He has served on many national and international committees. He was Secretary General of the Asia Oceania Geosciences Society (AOGS) during 2010-2012, the President of AOGS’s Ocean Section from 2009-2010, and Founding President of AOGS’s Biogeosciences Section from 2012-2014. He has been an at-large member of the AGU Ocean Sciences Section Executive Committee since 2013. He was a co-chair of the Programme Committee of OceanObs’19 Conference.
