Hosea M. Nelson
Professor of Chemistry
Postdoc, UC Berkeley, 2015 (Prof. F. Dean Toste)
Ph.D., Caltech, 2013 (Prof. Brian M. Stoltz)
B.S., UC Berkeley, 2004 
Email: [email protected]
​Office: 357 Crellin Laboratory
Phone: 626-395-6072

Hosea earned a B.S. in Chemistry from University of California at Berkeley in 2004 and a Ph.D. from the California Institute of Technology in 2013 with Brian Stoltz. After postdoctoral training at University of California at Berkeley with Dean Toste, Hosea joined the UCLA faculty in 2015. In 2021, Hosea became a Professor of Chemistry at the California Institute of Technology. He is an avid fisherman and motorsports enthusiast (there are even pictures of him on the web wearing a NASCAR hat). Like most native San Franciscans, he spends most of his time talking about how much he loves the Giants, hates the Dodgers, and how much better S.F. is than L.A.
