Thomas Colcombet (born March 6, 1975) is a French theoretical computer scientist known for settling major open problems on tree walking automata jointly with Mikoà Âaj Bojaà Âczyk. Colcombet is currently a CNRS Research Director at Paris Diderot University.
Colcombet earned his undergraduate degree from ÃÂcole normale supérieure de Lyon (2000) and his doctorate from University of Rennes 1 (2004). Since 2004, he is a CNRS researcher, and a Research Director since 2016. He received the CNRS Bronze Medal in 2010.
Besides his work on tree walking automata, Colcombet contributed to ÃÂ-automata, particularly to state complexity of Büchi automata, and to various topics in logic in computer science.
He was involved in the development of the videogame Liquid War.
