I am an associate professor at the University of Northern Colorado in the School of Mathematical Sciences. I received my Ph.D. from the University of Connecticut in 2009 in mathematical logic. My research is in computability theory, specifically its connections to combinatorics and graph theory in particular. I am also the author of the open source textbook "Discrete Mathematics: an Open Introduction" available for free at http://discrete.openmathbooks.org. My personal page is http://math.oscarlevin.com.
