About
My full name is Morenikeji Neri, but I usually go by Keji. I am a postdoctoral researcher in the Logic group of the Technische Universität Darmstadt (from April 2025). I was previously a PhD student (2021-2025) in the University of Bath's Mathematical Foundations of Computation group under the supervision of Thomas Powell, defending my thesis in March 2025.
My main area of research focuses on the intersections of proof theory and probability theory, particularly within the framework of the proof mining program. Specifically, I am interested in Gödel's functional interpretation and its applications for understanding the computational content of results in analysis, stochastic analysis, and ergodic theory. I am also interested in computability theory and formalization using the proof assistant Lean (check out some of my work).

Teaching
I tutor a range of STEM subjects, at undergraduate level and below, privately (usually online) and I do some teaching for the University of Bath. Here is a list of the courses I have taught at the University of Bath.
- 2022: I tutored the Logic and semantics of programming languages module
