Srikrishna Sridhar - PhD, University of Wisconsin

alt text 

I have graduated in the Winter of 2014. My new and permanent website is here.

I was a graduate student at the University of Wisconsin working on problems in large scale mathematical optimization, and data analysis. I was very fortunate to be advised by three leading experts in the field of numerical optimization; Stephen J. Wright, Jeff Linderoth and James R. Luedtke. My thesis work involved modeling and solving discrete choice non-linear models for applications like health care, production planning, and machine learning.
