Gahl Shemy
I’m currently 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 general combinatorial topology/ commutative algebra. 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.
