Prof. Dr. Stephen Kobourov


Efficient Algorithms

Academic Career and Research Areas

Prof. Kobourov is the author of more than 250 publications covering diverse research areas from the design, analysis and implementation of efficient algorithms and algorithm engineering, to applications in information visualization, computational geometry, and graph drawing. His work is well funded through research grants, including multiple grants from the National Science Foundation, the Office of Naval Research, and the United States Department of Agriculture.

Prof. Kobourov received BS degrees in Computer Science and Mathematics from Dartmouth College in 1995 and PhD in Computer Science from Johns Hopkins University in 2000. He was at the University of Arizona as an Assistant Professor (2000-06), as an Associate Professor (2006-12) and as a Full Professor (2012-2024), where we also served as the Associate Director of the Data Science Institute. He has co-chaired the program committees for ALENEX, IEEE PacificVis, and GD and is an Associate Editor of JGAA, CGTA and IEEE TVCG.
