I am an Assistant Professor in the Department of Mathematics at The Ohio State University, Newark.
In 2012--2013 I was a Visiting Assistant Professor in the Department of Mathematics at Purdue University.
In 2010--2012 I was a Homotopy Theory Postdoctoral Fellow in the Department of Mathematics at the University of Western Ontario in Canada. Postdoctoral sponsor: J.F. Jardine.
In 2008--2010 I was a Postdoctoral Fellow in the Institut de Géométrie, Algèbre et Topologie at EPFL in Switzerland. Postdoctoral sponsor: K. Hess.
In 2003--2008 I completed my Ph.D. in Mathematics at the University of Notre Dame. Thesis advisor: W.G. Dwyer.

Short biography

My mathematical career began while I was in graduate school at MIT for a period of 6 years (1996--2002). I had entered MIT to study aeronautics and astronautics, and by the time I left I was working full-time on mathematics and was off to begin a PhD thesis in homotopy theory with W.G. Dwyer at the University of Notre Dame (2003--2008). After 5 years at Notre Dame I completed my doctoral thesis in Spring 2008 and was off to Switzerland to begin a postdoctoral fellowship position at EPFL in Lausanne with K. Hess as postdoc sponsor (2008--2010). Following Switzerland I was off to Canada to begin a postdoctoral fellowship position at the University of Western Ontario in London, Ontario with J.F. Jardine as postdoc sponsor (2010--2012). Following Canada I was in a one-year visiting assistant professor position at Purdue University (2012--2013), after which I began my current position as assistant professor. I live in Upper Arlington, Ohio, 10 minutes from the Columbus campus.

About my research

The areas I am interested in are homotopy theory and algebraic topology, and their interactions with closely related areas in mathematics---algebraic K-theory, algebraic number theory, algebraic geometry, homological algebra, and geometric topology.
