Samitha's research interests are in the analysis and control of networked cyber-physical systems with a focus on transportation and other urban infrastructure systems. In particular, he's interested in enabling efficient and sustainable urban transportation systems, by utilizing advances in information technology (e.g. the proliferation of smart phones and real-time communication), mathematical modeling and optimization, and new transportation paradigms such as mobility-on-demand systems. His research develops and utilizes mathematical tools from the areas of dynamic programming, stochastic network optimization, multi-commodity flow optimization and network load balancing.
