Si Tang's home page
I am an Assistant Professor in the Department of Mathematics at Lehigh University. Before
joining Lehigh, I worked as an Assistant Research Professor in the Department of Mathematics
at Duke University from 2017 to 2018. I received my PhD in Statistics in 2017 and PhD in Ecology and Evolution
in 2013, both from University of Chicago.
I am on leave and visiting the Mathematics Department at Northwestern University for the 2020-2021 academic year.
