Welcome
I am a math grad student at MIT, broadly interested in arithmetic geometry and especially in points on varieties. My advisor is Bjorn Poonen.

Apr 2, 2024 | I will be travelling to Seattle to talk in UW’s Number Theory Seminar. Exactly what I will talk about is still TBD. |

I gave a talk at JMM this year on my 2-Selmer paper. I will also be talking about it again soon at

Nov 29, 2023 | Various coauthors and I posted a new paper on arxiv, in which we compute the Brauer group of the moduli stack \(\mathscr Y_0(2)\) parameterizing elliptic curves equipped with a cyclic subgroup of order \(2\). |
Oct 12, 2023 | I posted a new paper on arxiv. It is about bounding the average size of \(2\)-Selmer groups of elliptic curves \(E\) over characteristic \(2\) function fields. It also produces some new bounds on \(\dim_{\F_2}\Sel_2(E/K)\) when \(\Char K=2\) (and \(K\) is a global function field). |
Aug 2023 | I’m gonna try running a seminar on modularity and Fermat. |
