Broadly speaking, I like to implement homotopy theoretic thinking to geometry/algebraic geometry.
Factorization Algebras and Motivic Homotopy Theory
I am working on incorporating ideas and, more concretely, filtrations from the theory of chiral/factorization algebras to study homotopy types (e.g. of certain mapping spaces)…
1.1 Factorization Algebras in Unstable Motivic Homotopy Theory I: Contractibility of Ran Spaces (draft – comments welcome!)
Proves contractibility of a version of the Ran space in unstable motivic homotopy, with a view towards nonabelian Poincare duality.
1.2 Factorization Algebras in Unstable Motivic Homotopy Theory II: Nonabelian Poincare Duality. (in preparation)
2. Motivic Homotopy Theory
I also like to think about motivic homotopy theory from the point of view algebraic geometry and -theory…
To appear in “Surveys on Recent Developments in Algebraic Geometry (Edited with Izzet Coskun, and Tommaso de Fernex), in the Proceedings of Symposia in Pure Mathematics” [Arxiv:1605.00929].
Proves that modules over MW-motivic cohomology is the Déglisé-Fasel spectrum using Barr-Beck-Lurie [Arxiv:1708.05651] (Last updated: Aug 22 2017).

The localization of a Landweber exact theory at étale motivic cohomology is a universal way of imposing étale descent. [Arxiv:1711:06258] (Last updated Nov 16 2017).
2.5 Étale Framed Motives.
Sets up the theory of étale motivic spectra from the perspective of framed correspondences.
2.5 Twisted Homotopy –theory and Twisted Cycle Class Maps. (in preparation)
Twists certain cycle class maps by an Azumaya algebra via motivic homotopy theory.
Introduces and computes the motivic Dyler-Lashof algebra.
3. Étale Homotopy Theory
and I like the point of view that étale homotopy types are shapes of (higher) topoi.
3.1 Relative étale realization of motivic spaces. (with David Carchedi)
A motivic version of the theory of relative étale realization of Barnea-Schlank.
