Hey! I'm Hari, a student at University of Maryland and an avid CTF player, interested in cryptography and security.
My email address is emh (at) umd.edu.
Main Interests
I am mainly interested in cryptography and network security. I specifically study post quantum lattice based protocols, threshold cryptography, and secure multiparty computation. I also enjoy learning about math, and some topics I am interested in include algebraic number theory and elliptic curves.
Experience
- Research Assistant at MC2, working on zero knowledge, PQC, and MPC
- President of CSEC@UMD
- Cryptography Intern at Trail of Bits; worked on implementing Post Quantum Key Encapsulation
- Research Assistant at REU CAAR; worked on security estimation and PQC

Free Time
In my spare time, I like to cycle, climb, cook, and occasionally play the saxophone. I also enjoy playing badminton and table tennis.
I also enjoy messing with amateur radio. My call sign is KC3MGG.
