I was a PhD student until May 2012. I was working on optimization based model reduction algorithms for linear time invariant, linear parameter dependent systems and structured sytems. I have moved to Stan group in the Centre for Synthetic Biology and Innovation in the Department of Bionengineering at Imperial College.
