Ecotoxicology of Lampricides

Sea lampreys, a parasitic, jawless vertebrate that feeds by sucking the blood from fishes, invaded the Great Lakes in the early 20th century, decimating native fish populations. Sea lamprey populations are now controlled by applying the pesticides 3-trifluoromethyl-4-nitrophenol (TFM) & niclosamide to streams containing larval sea lampreys. While this has contributed greatly to lowering  lamprey populations & the rehabilitation of Great Lakes fisheries, research is needed to learn more about how these agents work, to improve their effectiveness, &  to predict & minimize adverse effects on non-target organisms.


We are looking for an enthusiastic Ph.D. graduate to join the Aquatic Toxicology & Physiology labs of Dr. Michael Wilkie, Allison McDonald & Jonathan Wilson to lead studies and mentor graduate students investigating the physiological effects and mechanisms of niclosamide and TFM toxicity to non-target fishes and lampreys. Using state of the art facilities, the postdoctoral fellow will use microrespirometry, molecular biology, whole animal respirometry and biochemistry to learn about how lampricides adversely affect fundamental mitochondrial metabolism, physiological performance and lampricide pharmacokinetics by sea lampreys, trout, lake sturgeon and other species. Experience with sub-cellular and biochemical analyses, toxicology, molecular biology, analytical chemistry, fish energetics, or gill function would be an asset.

Sponsored by the Great Lakes Fishery Commission, the 2 year appointment (renewable) is based in the Department of Biology, Wilfrid Laurier University and includes field work and travel. The start-date is September 2019 (negotiable), with an annual salary of $40,000–45,000 based on experience. Applications will be accepted until April 30, 2019 or until a suitable candidate is selected.
