# Research

I've been working most recently studying Picard groups of perfectoid spaces, and more generally studying vector bundles and cohomology on perfectoid covers of varieties and schemes, specifically how to parametrize such objects and how they
behave across characteristics (i.e., under *tilting*). Here is a selection of papers and preprints:

- Searching for Rigidity in Algebraic Starscapes (2021, Joint with Shuchang Xu,
*to appear in the Journal of Mathematics and the Arts*). - Untilting Line Bundles on Perfectoid Spaces (2021,
*to appear in International Mathematics Research Notices*). - On Picard Groups of Perfectoid Covers of Toric Varieties (2020, Submitted, joint with Anwesh Ray and Peter Wear).
- Projective Geometry for Perfectoid Spaces (Münster J. of Math. 14 (2021), 445–484).
- Projective Geometry for Perfectoid Spaces (2018, PhD Thesis, longer version of the paper above, including more exposition and foundation.
**Beware**: Errors that were corrected or removed in the published version may still appear). - The Combinatorics of Interval Vector Polytopes. (2012,
*E. Journal of Combinatorics*, Joint with Matthias Beck, Jessica De Silva, Joseph Pruitt, and Amanda Ruiz.)
