Hi! I study number theory and algebraic geometry. I'm interested in abelian varieties over number fields and finite fields, low-genus curves, Galois representations, modular forms, and applications in cryptography. My advisor is Larry Washington. I am currently the President of the Directed Reading Program at UMD.  

You can contact me at bloom@math.umd.edu. My office is Room 4400 in the Mathematics Building. My office hours for MATH 140 (Fall 2017) are Tuesdays and Thursdays, 1:00-2:00pm, and by email appointment.  

You can find my CV here (and a one-page Resume here). They were last updated in October 2017.  

I fence at the DC Fencers Club. I am an organizer of Tikkun Leil Shabbat.
