Hsien-Chih Chang 張顯之 Assistant Professor Theory Group Department of Computer Science Dartmouth College Email: hsien-chih.chang@dartmouth.edu Curriculum Vitae Research Interests My current research interests revolve around discrete/computational topology and geometry and connections to efficiency of computation. I usually find simple objects (like polygons, curves, planar graphs, surfaces and meshes) cute and attracting. Well, actually, anything with the word "algorithm" or "topology" catches my attention. Research Projects Papers Amazing junior researchers supevised by me. Go check out their work. Jonathan Conroy: PhD candidate. Metric embedding and sketching. Reilly Browne: PhD student. Optimization on geometric objects. Teaching Fall 2024: COSC 149 All about Planar Graphs (syllabus) Winter 2025: COSC 30 Discrete Mathematics (old syllabus) Spring 2025: COSC 39 Theory of Computation I love chickens. Look at all those chickens. Chicken chicken chickens. Repeat after me: Gallus gallus domesticus.
