Dr Chee Khian Sim
I am a senior lecturer with the School of Mathematics and Physics, and a member of the Centre for Operational Research and Logistics (CORL), at the University of Portsmouth. My main duties and responsibilities include teaching operational research course units, as well as research in optimisation/operational research.
I obtained my PhD (specialising in optimisation) in 2005 from the National University of Singapore, and MSc (also specialising in optimisation) from the University of Washington, Seattle. I have been with the National University of Singapore and The Hong Kong Polytechnic University for a number of years before joining the School of Mathematics and Physics at Portsmouth.
- First and second order methods to solve optimization problems, such as, subgradient methods on convex/nonconvex optimization problems and interior point methods on conic optimization problems.
- Supply chain optimization, in particular, optimal inventory management.
