Fisher is campus lead for the UC Water Security and Sustainability Research Initiative (UC Water)

Fisher is a co-PI and campus lead for the Center for Dark Energy Biosphere Investigations (C-DEBI)

I am looking for two graduate students to join UCSC Hydrogeology Group in Fall 2017 (apply by January 5, 2017). See more information here.

I might be looking for a postdoc to join UCSC Hydrogeology Group in 2017. See more information here.
