Pavol Hell is a Canadian mathematician and computer scientist, born in Czechoslovakia. He is a professor of computing science at Simon Fraser University. Hell started his mathematical studies at Charles University in Prague, and moved to Canada in August 1968 after the Warsaw Pact invasion of Czechoslovakia. He obtained his MSc from McMaster University in Hamilton, under the joint supervision of Gert Sabidussi and Alex Rosa, and his PhD at the Universite de Montreal, with Gert Sabidussi. In his PhD research he pioneered, on the suggestion of Gert Sabidussi, the study of graph retracts. He describes his area of interest as "computational combinatorics", including algorithmic graph theory and complexity of graph problems. His current focus is on nicely structured graph classes, and on the complexity of various versions of graph homomorphism problems.
