Donald M. Davis (born 7 May 1945) is an American mathematician specializing in algebraic topology.

Davis received a B.S. from MIT in 1967 and a PhD in mathematics at Stanford in 1972, directed by R. James Milgram. After postdoctoral positions at University of California, San Diego and Northwestern University, he began a 50-year career at Lehigh University in 1974. In 2012 he was named an inaugural Fellow of the American Mathematical Society.^[1]. Since 2002, he has been Executive Editor of Homology, Homotopy and Applications.

Research

Davis has published in algebraic topology, differential topology, topological robotics, and combinatorial number theory. He is an expert on immersions of projective spaces, and maintains a website with all known results for real projective spaces.Cite error: There are <ref> tags on this page without content in them (see the help page). He computed the -periodic homotopy groups of all compact simple Lie groups.

Coaching

In 1993 Davis started the Lehigh Valley Math Team. In 2005, 2009, 2010, and 2011, they were national champions in the American Regions Math League (ARML). They have finished second or third in ARML seven other times.^[2] They won the {\it Harvard/MIT Math Tournament (HMMT} in 2023 and 2024, and the {\it Princeton University Math Competition (PUMaC)} in 2009, 2010, 2012, and 2024.

Running

From 1977 through 2009, Davis competed in marathon and ultramarathon races. He was the overall winner of ultramarathon races of 31 to 78 miles in the 1970's, 1980's, 1990's, and 2000's.
