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. 

Jan 2024 
I gave a talk at JMM this year on my 2Selmer paper. I will also be talking about it again soon at

Nov 29, 2023  Various coauthers 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.
