 My CV.
I received a Ph.D. in 2010 in Mathematics with designated emphasis in genomic and computational biology from the University of California Berkeley. My advisors were Bernd Sturmfels and Lior Pachter.
During 20102011, I was an NSF Postdoctoral Fellow in the Department of Mathematics
at Duke University. During 20112014, I was an NSF Postdoc and L.E. Dickson Instructor in the Department of Mathematics at the University of Chicago.
I was an undergraduate at the University of Chicago; view the Chicago Mathematics Alumnae Project.
