My research focuses on the addressing important fisheries resource management questions in estuarine and marine environments in California, Oregon, Washington and Idaho.

I employ an interdisciplinary approach, linking innovative technologies such as, otolith micro-chemistry and microstructure to reconstruct the migration history and growth of threatened and endangered fishes with collaborators in genetics, fish health, and population modeling to understand how climate change, habitat restoration and resource management actions affect fish populations. I have research projects in coastal salt marshes and sea grass beds, pelagic estuarine habitats and riverine habitats of the San Francisco Bay-Delta Estuary, Columbia River and Estuary and the lower Colorado River. Species of interest include, Chinook salmon, coho salmon, steelhead trout, longfin smelt, delta smelt, longjaw mudsucker, rockfish sebastes sp. razorback sucker, green and white sturgeon.
