The Center welcomes Dr. Thomas Helser as leader of the Resource Ecology and Fisheries Management (REFM) Division's Age and Growth Program.

Tom's interest in fisheries began as a Peace Corps volunteer in Nepal, after receiving a Bachelor of Science degree in biology from the University of Wisconsin in 1982.

Tom went on to earn a Master of Science degree in marine fisheries from Auburn University in 1987 and a Ph.D. in fisheries oceanography from Louisiana State University in 1992. This lead to a position as a stock assessment scientist with the Population Dynamics group at the Northeast Fisheries Science Center in Woods Hole, Massachusetts. There he worked on groundfish assessments and silver hake population dynamics, biology, and life history.

Tom moved to the West Coast and joined the Northwest Fisheries Science Center where he served as Team Leader of the Groundfish Stock Assessment group before his recent appointment to the AFSC as Age and Growth Program Manager.

While Tom's research has varied, its central theme is in quantitative analysis and includes published peer-reviewed articles in bioeconomic modeling, stochastic population modeling, mixed-effects models of life history parameters, and growth models using Bayesian hierarchical meta-analysis. Tom's current research interests focused on statistical methods of modeling fish growth and life history variability both within and across taxonomic groups, as well as modeling growth responses to environmental processes.

Dr. Bernard Megrey of the Center's Recruitment Processes Program and his coauthors were recently recognized by the American Fisheries Society for the best paper published in 2008 by the Transactions of the American Fisheries Society:

Rose, K.A., Megrey, B.A., Hay, D., Werner, F., Ware, D.M. and Schweigert, J. (2008). Climate regime effects on Pacific herring growth using coupled nutrient-phytoplankton-zooplankton and bioenergetics models. Transactions of the American Fisheries Society 137:278-297.

The authors built upon an international cooperation established through PICES (North Pacific Marine Science Organization) to build and use coupled biophysical models to better understand and predict production variability in fisheries.
