Summary
👤
Senior🎓
Top SchoolKristina Sojakova is an Assistant Professor at VU Amsterdam with 11 years of experience blending programming languages, type theory, and security to produce mechanically verified proofs for cryptographic and distributed systems. Her work bridges deep theory and practical tooling—she contributed to the Coq HoTT library formalizing sequential colimits and has driven formal verification of Tezos smart contracts and token standards in industry settings. A former member at the Institute for Advanced Study and a Cornell postdoc, she developed novel logics (IPDL) and rewiring-based approaches for semi-automated security proofs that scale to distributed protocols. Kristina’s research often makes dependency and categorical structure first-class citizens in security proofs, revealing subtle connections between homotopy/type-theoretic ideas and applied cryptography.

Contributions summary:Kristina primarily developed a Coq library for Homotopy Type Theory. Their contributions focused on formalizing and implementing concepts related to sequential colimits within this library. The code changes involved defining and manipulating various mathematical structures, including type sequences, diagrams, and colimits, along with proving relevant properties and equivalences. The user demonstrated a strong understanding of type theory and category theory to build this library.
