This completed Master thesis project of Nicolas Mischke was jointly supervised with Atruvia and implements a self-supervised prompt optimization framework that improves a retrieval augmented generation system without needing a labelled dataset of user queries.
This completed Bachelor thesis project of Lars Heimann was jointly supervised with the viadee Unternehmensberatung AG and investigates the optimization of large language model pipelines via automatic prompt optimization in the industrial context of accounting.
This completed Master thesis project of Oguz Caymazer was jointly supervised with AUDI AG and Dr. Marleen Voß and develops and evaluates a retrieval augmented generation system which can extract precise technical information from a large database of documents.
This completed Bachelor thesis uses Proximal Policy Optimization in order to develop a Deep Reinforcement Learning Agent that can make informed trading decisions given historical stock data.
I acted as an assessor in the Confirmation of Status viva of a PhD student in Operator Algebras. In Oxford, the Confirmation of Status is a preliminary thesis examaniation which every PhD student has to pass in order to get admitted to the final exam.
In this lecture course for the MSc. Information Systems, I gave three lectures on the transformer model architecture - mostly focusing on applications in natural language processing. You can find the slides here.
In this seminar for the MSc. Information Systems, we dive deep into the transformer model architecture and its applications in computer vision, time series forecasting and natural language processing.
Together with Dr. Dennis Wulle and Ann-Kathrin Meyer, I prepared and conducted this one-week intensive mathematics course which prepares economists for their mathematical exam.
Together with Rafaela Gesing, Grigoris Kopsacheilis and Petr Naryshkin, I organized a learning seminar on Ian Putnam's book on Cantor minimal systems.
I assisted and supervised teacher trainees in teaching Mathematics to first-year students.
I conducted a mathematical help-desk and conducted workshops (LaTeX, proof techniques) for first-year Mathematics students. During this time, I not only learned a lot from my students, but also benefitted from pedagogical workshops conducted by the Institute of Mathematics Education and Computer Science Education.
I designed the weekly homework sheets with solutions and coordinated for the courses Complex Analysis, Introduction to Analysis, Topology and Geometry and Analysis I.
I conducted several exercise classes in both Münster and Oxford one topics such as Analysis, Linear Algebra, Operator Algebras, Topology, Elementary Number Theory, Functional Analysis and K-theory.
