I am Taekang Hwang: [tʰɛ.gaŋ hwaŋ], a Ph.D. student in the ISE Department at Korea Advanced Institute of Science and Technology, South Korea. My research interests span the theory of integer programming, combinatorial optimization, polyhedral combinatorics, and algorithms for discrete optimization. Currently, I am actively working on various topics related to cutting-plane methods for urban transportation problems, such as the traveling salesman problem with drone and the crew scheduling problem.
