Nicolas Gutierrez

Nicolas is originally from Uruguay where he has conducted ecological research both in his home country and in the Antarctic, mainly focused on population dynamics of penguins and sea lions. In fisheries, he has collaborated in stock assessments of a scallop species and worked as onboard observer in shellfish and finfish fisheries. He did his MS thesis working on spatial patterns in population dynamics of the Patagonian scallop and its fishery implications.

He started his PhD program in 2004 focused on spatially-explicit modeling and management of sedentary resources. He is particularly interested in the sea urchin-kelp dynamics and in fine-scale spatial responses of urchins to harvesting, through cellular automata and individual based models.


Allan Hicks

Allan Hicks grew up fishing in Canada and California, and working at a fish market on the pier in Avila Beach. He has earned a B.S. in Fisheries with an Applied Math Minor from Humboldt State University and a M.S. in Statistics from the University of Idaho. While working in New Zealand for the National Institute of Water and Atmospheric Research he met Ray Hilborn.

Shortly thereafter, in 2004, he started working towards a Ph.D. in Fisheries with a focus on issues related to the stock assessment of orange roughy in New Zealand. Some example issues are the occurrence of hyperdepletion in the commercial fisheries, the use of age data in the assessments, and the use of industry vessels to perform acoustic surveys. He often travels to New Zealand to perform stock assessments and attend working group meetings. Anything quantitative interests him, especially Bayesian methods and computer intensive analyses.


Larry Lestelle 

Larry is back in school after gaining some experience in the working world. He earned his BS and MS in Fisheries Science at the University of Washington in the 1970s. His MS project addressed effects of logging on salmonids on the Olympic Peninsula. Following school, he worked for the Quinault Indian Tribe as a fish biologist until 1990, when he went into consulting, working to the present on various projects from California to Alaska. Most of his recent work has focused on the effects of environmental changes on salmonid populations, analyzing potential effects through habitat modeling. Passionate to learn more, Larry started working towards his PhD in the Hilborn lab in September 2006. He is focusing on life history dynamics of coho salmon on the Washington Coast, utilizing data still being collected through a study he initiated in 1980.


Jocelyn Lin

Jocelyn is currently a PhD student being co-advised by Ray Hilborn and Lorenz Hauser. She earned her BS in Ecology and Evolutionary Biology at Yale University and then spent a year in Shizuoka City, Japan as a Fulbright Fellow studying tuna sashimi production and consumption. She obtained an MS from the School of Aquatic and Fishery Sciences in 2007, with her thesis "Genetic divergence among distinct phenotypes of sockeye salmon (Oncorhynchus nerka)." For her PhD, Jocelyn plans to model the effects of selection on wild populations of sockeye salmon, to determine how environmental factors may influence patterns of genetic and phenotypic differentiation in these fish. She works with both the UW Alaska Salmon Program and the fisheries group of the UW Marine Molecular Biotechnology Laboratory.


Arni Magnusson

Arni started his Ph.D. studies at the School of Aquatic and Fishery Sciences in 2002, after defending his M.S. degree at the same school. The title of his M.S. thesis is "Survival rates of coho and chinook salmon released from hatcheries on the U.S. and Canadian Pacific coast 1972-1998, with respect to climate and habitat effects," UW Thesis no. 51263. His current research topics are age-structured stock assessment models and analysis of how informative input data are about current stock size.


Carey McGilliard

Carey earned a BA in mathematics at The College of Wooster in Ohio in 2000. She worked as a statistical programmer and researcher at The Urban Institute, a non-partisan social policy think tank and as a researcher in biophysical forcing and zooplankton ecology at University of Maryland Center for Environmental Science. Her current interests include population dynamics modeling, statistics, spatial management, larval fish biology, and bioeconomics. Specifically, she is looking at the effects of using Marine Protected Areas (MPAs) in addition to effort limits and the influence of larval biology, age structure, and bioeconomics on the effectiveness of management with MPAs.


Suresh Sethi

I grew up in Anoka, MN and completed a B.S. in Zoology at the Center for Limnology, UW–Madison in 2001. I spent the next four years doing marine community ecology research, traveling, and working in the socially responsible investment industry before returning to graduate school. As humans are one of the main drivers of ecosystem disturbance, I am interested in studying quantitative ecology as well as motivations for human behavior such as economics towards effective resource use and conservation. In my Master's research, I am using spatial biological models to examine how poaching affects marine reserves as fisheries management tools. I will begin my Ph.D. in Fall 2007 where I plan to continue work on fishermen dynamics and resource management.

Areas of Interest: quantitative ecology, economics, fleet dynamics, fisheries.


Ryan Simmons

Ryan is working on his M.S. and joined the School of Aquatic and Fishery Sciences in 2006.  He earned a B.S. in Environmental Science from Western Washington University in 2003, where he focused his interests on aquatic systems and the ecological dynamics of freshwater-marine interfaces.  His interests led him to a unique program in New Zealand where he studied shortfin eel (Anguilla australis) dynamics in intertidal mangrove habitat.  Ryan went on to work in the fisheries consulting field where he partook in a variety of Pacific salmon and native char habitat studies along the West Coast.  His Masters research will focus on juvenile sockeye dynamics in the Chignik Lake system on the Aleutian Peninsula in Alaska.  Field and quantitative methods will be developed to characterize the ecological role of the coastal estuary in relation to the freshwater rearing environment in the system.  Ryan is interested in the application of quantitative ecology to changing systems and using the variety of animal life patterns to quantify population dynamics and stability.


Juan Valero

Juan is a Ph.D. student in the SAFS since 2002. Original from Argentina, he has interests and expertise in marine ecology and fisheries. His ecological research has focused on ecology and life history strategies of shellfish and finfish species. In fisheries, he has worked as onboard fishery observer and investigator in quantitative assessments of shellfish and finfish fisheries. His PhD research is on spatial dynamics, recruitment trends and sustainability of the Geoduck clam (Panopea abrupta) from a metapopulation perspective. This project integrates directed sampling and experiments with software development for metapopulation modeling of benthic / sedentary species under exploitation.

Special Interests: Metapopulations and Spatial Explicit Modeling - Population Dynamics - Spatially Structured Populations - Quantitative Stock Assessment - Software Development
