Education

  • Ph.D. - Fisheries and Wildlife Science, Virginia Polytechnic Institute and State University, 2005
  • M.S. - Statistics, Virginia Polytechnic Institute and State University, 2001
  • M.S. - Fisheries and Wildlife Science, Virginia Polytechnic Institute and State University, 1999
  • B.S. - Biological Sciences, South Dakota State University, 1996

 

Background

As Associate Director for the Quantitative Fisheries Center, I have daily administrative oversight of the QFC. I am responsible for QFC budgeting and am the point-of-contact for QFC Supporting Partners and our Board of Advisors. I also hold a fixed-term Associate Professor position in the Department of Fisheries at Wildlife at Michigan State University, where I conduct research on the ecology and population dynamics of managed fish populations in the Great Lakes. Research projects with which I have been involved include a natural mortality estimation project for lake whitefish stocks in lakes Huron and Michigan, and a modeling project to determine possible consequences to changes in salmonine stocking practices in Lakes Huron and Ontario. I also help develop and teach workshops, short courses, and on-line courses on quantitative fisheries topics.

Although I was born in North Dakota, I was raised in Rapid City, South Dakota. I received a BS degree in Biological Sciences from the Department of Wildlife and Fisheries Sciences at South Dakota State University. I then attended graduate school at Virginia Polytechnic Institute and State University in Blacksburg, Virginia, where I received MS and PhD degrees in Fisheries and Wildlife Sciences and an MS degree in Statistics. My thesis research involved an experimental evaluation of early competitive interactions between largemouth bass and bluegills. For my PhD research, I studied a riverine muskellunge population in southwest Virginia. There were several facets to this research, including evaluating effects of alternative harvest regulations on the stock and studying how changes in river discharge influenced fish habitat use and selection.

Shortly before completing my PhD, I moved to Michigan and worked as a Post-Doctoral Research Associate at the Institute for Fisheries Research, which is a Michigan Department of Natural Resources Research Station located at the University of Michigan in Ann Arbor. My research at IFR was related to the development of a classification system and risk assessment for rivers in Michigan, Wisconsin, and Illinois streams.

Research

Project Title: Simultaneous Analysis of Genetic and Age Data to Estimate Stock Contribution for Mixed-Stock and Strain, Open-Water Fisheries in the Great Lakes

Using genetic and age composition data, we are developing new methods for identifying stock and cohort contribution to admixed, open-water fisheries. This innovation will improve the ability to evaluate stock-specific recruitment from routine assessment or harvest data. The usefulness and performance of this new method will be demonstrated with simulations and applications to Great Lakes stocks of lake sturgeon, lake trout, and walleye, which range in longevity, aging uncertainty and geographic scale of movements.


Project Title: Estimating Mortality Parameters for Walleye in Lake Erie

The purpose of this research is to use the historic jaw tag database for walleye on Lake Erie and provide corrected estimates of natural (M) and fishing (F) mortality rates based on jaw tag loss and fishery-specific tag reporting rates.  Furthermore, using PIT tags, we will evaluate an alternative method of estimating F and M for Lake Erie walleye which does not rely on fishers reporting tagged walleye.  We will also provide the LEC managers with recommendations regarding future tagging studies taking into account, tagging frequency, number of fish to tag and tagging methodology. 


Project Title: Assessing Lake Michigan Salmonine Stocking Policies Using Decision Analysis

The goal of this project is to develop an updated Decision Analysis model for salmonine stocking program on Lake Michigan. Historically, stocking of hatchery-reared fish is one of the primary management tools available to fishery managers working on Lake Michigan. Since the beginning of major salmonine stocking programs in the mid-1960s, hundreds of millions of Chinook salmon, lake trout, rainbow trout, brown trout, and coho salmon have been stocked to support recreational fishing opportunities, restore native lake trout populations, and reduce the abundance of alewife. In the early years of the Lake Michigan salmonine stocking program (1970s and 80s) stocking rates increased as production capacity increased, with little attention given to forage availability. In the late 1980's, however, an outbreak of Bacterial Kidney Disease in Chinook salmon led to a dramatic decline in salmon numbers and harvest. These declines are widely viewed as having resulted from excessive abundance of stocked predators during this period. Therefore, the challenge is that the selection of optimal salmonine stocking polices requires a tradeoff between stocking too many fish, leading to an excess of predators relative to the supply of prey and consequently a decline in prey abundance, and stocking too few predator fish, thereby allowing alewife abundance to rise to undesirable levels and foregoing potential harvest of predators. In this case, we work closely with fisheries managers to conduct a decision analysis of alternative management options, using stochastic simulation to forecast the most likely consequences of a range of stocking rates and Bayesian statistical approaches to account for the uncertainty associated with these forecasts.
