Research Overview
We live in the Anthropocene, where global ecology is dominated by human activity. My research seeks to understand how fishes respond and adapt to abrupt environmental change across levels of biological organization. Work in my lab addresses this overarching question through the combination of field, laboratory, meta-analysis, and modeling approaches. Additionally, I have pending proposals to explore aspects of the pike invasion to Southcentral Alaska and to apply stage-specific salmon life cycle models to Western Alaska Chinook populations
Current Research Projects
  • Causes and consequences of chum salmon straying in Southeast Alaska
  • Adaptation of Bristol Bay sockeye salmon to a warming world
  • Collective navigation during homing migrations by salmonids
  • Evolutionary rescue as villain and savior in nature
  • Patterns and processes in straying by Pacific salmon and steelhead
  • Adaptive phenotypic plasticity and successful invasion
