Current Research
A central theme of my research is applications of higher category theory to topology and differential and algebraic geometry. In particular, I am interested in derived geometry. I also maintain an active interest in field theory.
One of the larger endeavors I am working on is the development of a suitable framework for (infinite dimensional) derived differential geometry, tailored towards applications to field theory. This project is supported by a joint NSF topology grant, with Owen Gwilliam. This builds upon (still ongoing) work of mine with D. Roytenberg centered around modeling derived manifolds using differential graded manifolds.
I have also been actively researching the interaction between étale and motivic homotopy theory.
Finally, I have been working in the field of log geometry with Sarah Scherotzke, Nicolo Sibilla, and Mattia Talpo. We are currently investigating log étale K-theory.
I have many other projects as well.
