Short Mathematical 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 with the aim of studying homotopy theory under the guidance of Bill Dwyer (Notre Dame). I received my PhD in mathematics at the University of Notre Dame (2003--2008); my thesis was written under the direction of Bill Dwyer. From 2008 to 2010 I had a postdoctoral position at EPFL (Switzerland) to work with Kathryn Hess. I then obtained a postdoctoral position at the University of Western Ontario (Canada), where I remained from 2010 to 2012, working with Rick Jardine. I spent the 2012--2013 academic year as a visiting assistant professor at Purdue University. In 2013 I began my current position as assistant professor. I live in Upper Arlington, Ohio, 10 minutes from the Columbus campus (where I work with graduate students) and 35 minutes from the Newark campus (where I work with undergraduate students).

Workshop on Functor Calculus (OSU): March 16--17, 2019

We gratefully acknowledge funding from (i) the Math Research Institute (MRI) under the "OSU Department of Mathematics Thematic Year on Topology" and (ii) the NSF-RTG #1547357 Algebraic Topology and Its Applications".

Editor for

This is a relatively new fully refereed international journal, publishing original research papers in all areas of mathematics. TMJ is handled electronically by Project Euclid Publishers of Cornell University Library and Duke University Press, and is published by the Tbilisi Centre for Mathematical Sciences (TCMS), a non-governmental and non-profit independent academic institution founded in November 2008 in Tbilisi, Georgia. TCMS also publishes another mathematical journal, Journal of Homotopy and Related Structures (JHRS), printed by Springer.

Editorial interests: homotopy theory, algebraic topology, structured ring spectra, functor calculus, operads, algebras over operads

Current PhD Students

Research Interests

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.
