Summary
🤩
Rockstar🎓
Top SchoolZach Battleman is a Computer Science junior at Carnegie Mellon University and a Teaching Assistant with eight years of practical experience mentoring large cohorts and running focused recitations and office hours. He works as a research assistant with Prof. Jeremy Avigad to extend Lean 4’s theorem-proving capabilities, adding monadic interpretations, pre/postconditions, and loop invariants to simplify verification of imperative programs. Deeply interested in formal methods, programming language theory, and SAT solving, Zach also enjoys low-level systems work and has contributed backend ports to the prominent mathlib4 Lean library. His GitHub activity and research hint at a transition toward automated reasoning at scale, including exploration of massive parallelism for theorem proving. Outside research, he’s applied ML techniques in industry and academic internships, demonstrating an ability to move between formal theory and practical implementation.
