Anne J. Shiu
I am a Professor in the Department of Mathematics
at Texas A&M University.
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 2010-2011, I was an NSF Postdoctoral Fellow in the Department of Mathematics
at Duke University. During 2011-2014, I was an NSF Postdoc and L.E. Dickson Instructor in the Department of Mathematics at the University of Chicago.
