Herman Bergwerf

Welcome! This webpage contains information about my expertise and professional activity. I am specialized in solving difficult logical problems and implementing the solutions in software. Visual communication plays a key role in many of my projects, and I enjoy designing beautiful and innovative interfaces. I like brainstorming together with a team to find the path towards a good product, and to make technical descisions that are future-proof. I have an academic background in biophysics, pure mathematics, and theoretical computer science.


Technical skills

I have affinity with challenges across the software stack; both high-level and low-level. I like designing things, thinking about the interactions, and making sure everything is implemented in a modular and efficient way.

Machine Learning


Formal Verification

One of my academic specializations is formal verification using interactive theorem provers. I primarily use the Coq Proof Assistant, using which I have developed various formal theories. Developing formal proofs is very challenging, and requires careful thinking about even the smallest logical inferences. Below are some formalization projects I did in my spare time.

Academic background

In 2015 I started the Nanobiology Bachelor program at TU Delft. I was excited to learn about the molecular machinery and laws of physics that make life possible. While this fascination remains with me, I decided to move away from the empirical sciences to study mathematics and logic.

I moved to Nijmegen where they offer a strongly theoretical computer science track, including courses on Category Theory, Type Theory, Computability Theory, and Automated Reasoning. My interest in mathematics increased, and I followed courses about Axiomatic Set Theory, Model Theory, and Graph Theory.
