Current IPHC Responsibilities:

  • Oversee the oceanographic data collection program on the fishery-independent setline surveys
  • Liaison with NMFS to collect Pacific halibut data on groundfish trawl surveys
  • Larval distribution studies
  • Implementation of the undergraduate internship program
  • Publications

Background:

Began working at the IPHC in Spring of 1990 as a seasonal hire to work in the fishing ports.

Since being hired on a permanent basis in Fall of 1990, I have been involved in a variety of tasks. Some highlights include:

  • oceanographic data collection program
  • NMFS trawl survey data collection
  • larval distribution studies
  • undergraduate internship program
  • staff editor and publications coordinator
  • hiring and training of setline survey samplers
  • Pacific halibut bycatch viability training of NMFS observers
  • field (port and vessel) biologist

Education:

  • M.S. from University of Washington, B.S. from Oregon State University 

Research Activities:

  • The use of oceanographic data coupled with biological data collected on the setline survey to examine the effects of climate variability on the distribution of Pacific halibut.
  • Pacific halibut larval distribution and the connectivity of larvae between the Gulf of Alaska and the Bering Sea.
