Ryan Shartau
I completed my PhD at the University of British Columbia under the supervision of Dr. Colin Brauner where I investigated how vertebrates tolerate the very high CO2 levels (e.g. >30,000 uatm; 3 kPa CO2) found in many environments such as tropical freshwaters, aquaculture, and nests of reptiles. This work was conducted using over 20+ species of fish, as well as alligators and turtles. Following my PhD, I worked at Fisheries and Oceans Canada (DFO) at the Pacific Biological Station as a postdoctoral Research Scientist with Dr. Stewart Johnson investigating the impact of toxins produced by blue-green algae (cyanotoxins) on salmon physiology, and the presence of algal toxins in the marine water of southern British Columbia. After the DFO, I completed a short postdoc as a Mitacs Elevate Postdoctoral Fellow at the University of Prince Edward Island to identify biomarkers of algal toxicity in salmon. During my postdoctoral work I collaborated with Dr. Dan Baker at Vancouver Island University on white sturgeon physiology. Currently, I am an Assistant Professor in the Department of Biology at the University of Texas at Tyler. |
Brandon Ellingson
I obtained a BS in Fisheries Ecology from the University of Massachusetts Amherst in 2016, where I worked on several age and growth projects involving river herring. For the past 5 years and currently I am employed by the Atlantic Salmon Ecosystem’s Research Team, with a primary focus of marine growth and survival. Joining the UT Tyler master’s program, I am excited to investigate the changes in gene expression associated with the physiological impact of cyanotoxins on Atlantic salmon (Salmo salar) and Chinook salmon (Oncorhynchus tshawytscha) and identify biomarkers that may serve as useful indicators of toxin exposure for hatchery managers. |
Dillon Flowers
I completed a BS in Zoology, in 2021, from Weber State University in Ogden Utah. Where I completed research in the effects of ocean acidification on oyster shells Crassostrea virginica. I also worked on understanding the presence of mercury in fish populations found amongst public communities of northern Utah.
Here at UT Tyler's master's program I am investigating cellular mechanisms related to a survival strategy known as preferential intracellular pH regulation that some species of fish utilize under periods of hypercapnia. This strategy is the ability to maintain homeostasis in tissue pH while allowing large decreases in blood pH as CO2 increases in the water, and the genes with related transporters are largely unknown underling these biological processes.
