Alison is a fisheries research scientist in the Ecology Group. Her work focuses on examining the interaction between fishes and hydropower facilities. She is involved in several large studies that examine the passage proportions and survival of juvenile and adult salmonids that passed downstream through dams in the lower Snake and Columbia rivers. Alison is also involved in a number of laboratory studies that investigate the effects of rapid decompression associated with simulated turbine passage and the implantation methods of telemetry transmitters.

Research Interests

  • Fish passage and survival through hydropower facilities
  • Examination of barotrauma in fish due to passage through turbines and other water management structures
  • Optimal surgical procedures for implantation of transmitters
  • Applications of acoustic and radio telemetry

Education and Credentials

  • M.Sc. Biology, Carleton University, Ottawa, Ontario, Canada. 2009.
  • B.Sc. Forensic Science (Honours), Laurentian University, Sudbury, Ontario, Canada. 2007.
