Thanks for visiting my webpage.  I’m a fish ecologist and currently a Research Associate at the University of Washington in the School of Aquatic and Fishery Sciences.

I examine patterns and test hypotheses regarding the causes and consequences of the distribution, abundance, and movement of aquatic organisms. This includes determining the distribution and movement of animals (e.g., alewife, striped bass, blue catfish, crayfish and Pacific salmon) using telemetry and then relating those movements to environmental factors that cause them to stay or move. I also examine the relationships between ecological drivers and fishes including environmental heterogeneity, abiotic gradients, and anthropogenic activities.

Current Projects

  • Quantifying density, salmon smolt predation, and movement of piscine predators in the San Joaquin River, CA
  • Examining the distribution of Chinook and Coho salmon in Puget Sound, WA
