Professor Hyeong-Ah Choi's research lab centers its activities on graph and optimization algorithms in network problems and on analysis and design of algorithms relevant to modern massive data problems. Current projects include the development of low-complexity algorithms to find underutilized wireless channels in cognitive radio networks and the analysis of modern online education content in finding optimal learning paths.
