I am an Associate Professor in the Department of Mathematics & Computer Science. I earned a Ph.D. in Mathematics from Case Western Reserve University in 2016, an M.S. in Mathematics from the Ohio State University in 2012, and a B.S. in Applied Mathematics from Columbia University in 2008. I am a first-generation college student and Pell grant recipient.
