Gahl Shemy
I’m a third year math PhD candidate at the University of Michigan. I previously earned a math B.S. from UCSB in the College of Creative Studies. My mathematical interests include the cohomology of arithmetic groups, Steinberg modules, and homological stability. My advisor is Jenny Wilson.
I’m very grateful to be supported by an NSF Graduate Research Fellowship and a Rackham Merit Fellowship (Rackham Science Award).

Beyond learning and doing math, I enjoy teaching math, playing soccer, reading, skateboarding, skiing, hiking, dj’ing, and thrifting.
