About Me

I am a fish ecophysiologist currently conducting postdoctoral research at the University of Minnesota in Dr. Gretchen Hansen's lab. My work investigates how temperature — and the changes wrought upon it by a warming climate — shapes the physiology, ecology, and conservation of aquatic species.

My research spans a broad range of taxa and systems, from Chinook salmon in California rivers to Antarctic notothenioids beneath the Ross Ice Shelf, Great Lakes coregonids, green sturgeon, and threespine stickleback. A common thread runs through all of it: understanding how organisms are adapted to their thermal environments, how that adaptation varies among populations, and what it means for their survival under global change.

Outside the lab I enjoy sci-fi, mountain biking, watercolor painting, and escaping into the wilderness for camping, biking, hiking, and birding.
