Hi! I'm Artane Jérémie Siad. I completed my PhD with Prof. Arul Shankar at the University of Toronto in 2021. 

I am interested in number theory, especially arithmetic statistics and arithmetic topology. Lately, my work has mostly been at the interface between statistical anomalies in arithmetic invariants and new theories in arithmetic geometry. See these slides for a thread of things I've been thinking about recently. 

2021-2025, postdoc (member and instructor) at the IAS and Princeton University; 2022-2024, NSERC PDF. 

I am an assistant professor at the YMSC and Tsinghua University.
