Lecturer
Anne Baanen is a Lecturer in the Department of Computer Science at the Faculty of Science, Vrije Universiteit Amsterdam. They recently completed their PhD in theoretical computer science under the supervision of Jasmin Blanchette and Sander Dahmen as part of the Lean Forward project. Their current teaching responsibilities include coordinating the Logic and Modelling course and supervising projects in Computer Assisted Proofs. Their educational background includes double majors in Computing Science and Mathematics for both Bachelor's and Master's degrees at Utrecht University. During their time at Utrecht, they were active in student organizations, serving as chair of the programming committee WebCie and the LGBT+ organization TrotCie, while also contributing to the student newspaper de Vakidioot. Dr. Baanen's research operates at the intersection of computing science and mathematics, spanning intuitionistic logic, type theory, formal verification, and functional programming. Their work heavily involves the Lean theorem prover, focusing on formalizing advanced mathematical concepts like algebraic number theory, Dedekind domains, and class groups. They are particularly interested in the design of morphisms and substructures in dependent type theory, as evidenced by their presentations on bundling in type theory. Analysis of their publication record shows a consistent focus on formalizing mathematical structures using the Lean theorem prover, with particular emphasis on algebraic number theory and the design of effective type class systems. Their work bridges theoretical computer science and advanced mathematics, contributing to both the formal methods community and mathematical research. Dr. Baanen is also active in sustainable ecology, LGBT+ rights advocacy, and software freedom movements. Their teaching portfolio spans from Logical Verification to Grondslagen van de Wiskunde (Foundations of Mathematics), demonstrating both breadth and depth in computer science education. They have presented at numerous international conferences including CPP, ITP, IJCAR, and ICFP, establishing themselves as an emerging researcher in formal methods. Based in Amsterdam, they maintain an active research profile while contributing to the academic community through teaching and conference organization, including co-organizing the Formalization of Cohomology Theories workshop at BIRS in Banff, Canada.
