Sarah Giesy
Research Associate, Animal Science

I work in the laboratory of Yves Boisclair where we study hormonal regulation of metabolism using both in vivo and in vitro techniques. We utilize a variety of animal models including the dairy cow, sheep, and mice. I provide leadership in all phases of the research work performed by the laboratory: drafting protocols, designing, conducting and analyzing scientific experiments, and supporting the graduate and undergraduate lab members.
