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

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

I am looking for a postdoc to join UCSC Hydrogeology Group in 2016. See more information here.

I might admit a new graduate student to join UCSC Hydrogeology Group in Fall 2016. See more information here.
