Research Technician




  • M.S. – Fishery Management, University of Wisconsin – Stevens Point, 1980
  • B.S. – Fishery Management, University of Wisconsin – Stevens Point, 1977


I have spent the last four decades as a fishery assessment and research biologist working for Native American Inter-Tribal organizations in the Great Lakes basin.  I helped create research and assessment programs for two inter-tribal organizations with much of that work focused on monitoring commercial fishery harvests by tribal members exercising treaty-reserved fishing rights in lakes Superior, Huron, and Michigan.  Information collected during the monitoring of commercial harvests has been instrumental in development of statistical catch-at-age stock assessments for lake trout and lake whitefish and projecting total allowable catch for both species.  

I represented tribal governments on inter-agency technical committees for most of my career.  I participated in activities of the lake Superior, Huron, and Michigan technical committees and was chairman of the Superior and Huron technical committees.  The technical committees strive to monitor the status of fish populations and habitat in each Great Lake and conduct coordinated research activities that help evaluate progress toward achieving management objectives established by the lake committees.

I also spent a substantial amount of time participating in sea lamprey control activities. I helped establish an in-stream trapping program for adult sea lamprey that was used to extrapolate lake-wide abundance.  I worked for the Great Lakes Fishery Commissions to quantify sea lamprey-induced mortality of fish in the Great Lakes and helped create the current sea lamprey marking targets being used to evaluate efficacy of the sea lamprey control program on the Great Lakes.  While at the Great Lakes Fishery Commission I helped lay the groundwork for the current salmonid Mass Marking Program.
