Erin Arms
Senate Office of Research


Erin received a PhD in Genetics from the University of California, Davis where she studied water stress tolerance in tomatoes, with the goal of identifying ways to improve tolerance to drought and other types of water stress. She did her undergraduate work at the University of Washington, where she received a BS in Biochemistry, and a BA in Anthropology.

Erin was awarded a AAAS Science & Technology Policy Fellowship. Her placement is with the National Institutes of Health (NIH) at its National Institute of Allergy and Infectious Diseases (NIAID), where she works as a Health Policy Analyst at the NIAID Office of Communications and Government Relations.

Emily Berry
Assemblymember Cooley


Emily received a Ph.D. in cell biology from the University of California, San Francisco. She performed her thesis research at the Gladstone Institutes where she studied how factors important during normal heart development can be leveraged to improve heart function after heart attack.

Emily was hired by the Office of Assemblymember Ken Cooley (D-Rancho Cordova) as Legislative Aide.

Dan Brumbaugh
Senate Environmental Quality Committee


Dan received a Ph.D. in Zoology from the University of Washington where his research focused on how marine organisms adapt to their environments. Dan earned undergraduate degrees in Biology and Art History from Stanford University. Immediately before coming to Sacramento, Dan was a researcher at the University of California, Santa Cruz, where he studied marine science and conservation. Dan has taught graduate and undergraduate courses at the University of Washington, Santa Clara University, and UC Santa Cruz.

Dan is currently a Consultant with The Nature Conservancy Northern Caribbean Program, studying coral reef management issues in The Bahamas. He also is an Associate Researcher with the UC Santa Cruz Institute of Marine Sciences.

Sarah Carvill
Senate Transportation & Housing Committee


Sarah grew up in San Francisco and received both her Ph.D. and her BA in Environmental Studies from the University of California, Santa Cruz. Her dissertation research focused on timber policy and water quality on California’s North Coast. She also holds an MS from the University of Montana, where she studied rancher involvement in ecosystem restoration.

Sarah is currently a Lecturer in Environmental Studies at her alma mater, UC Santa Cruz.

Matthew Dumlao
Senate Natural Resources Committee


Matt received his Ph.D. in Soils and Biogeochemistry from the University of California, Davis studying how plant roots affect soil erosion and the flow of nitrogen through soils. He has a MA in Ecology and Evolutionary Biology from University of Colorado at Boulder and a BS in Plant Biology from UC Davis.

Matt was hired by the Office of Senator Henry Stern (D-Canoga Park) as a Consultant.

Diana Lin
Assemblymember Quirk


Diana earned a Ph.D. in environmental engineering and science from Stanford University and a BS in chemical engineering from the California Institute of Technology.
