Klemens Flöge

Biography

I am a researcher with a strong interdisciplinary background in applied mathematics, electrical engineering, and management. I completed my MASt in Applied Mathematics (Part III of the Mathematical Tripos) at the University of Cambridge, where I focused on statistics and probability. Prior to that, I earned a BSc in Electrical Engineering and Information Technology from ETH Zürich, specializing in quantum photonics and control.

Recently, I was working as an ML researcher at Helmholtz AI, where I focus on uncertainty quantification for large language models, cross-modal protein retrieval, and Bayesian inference techniques. My research has been published on platforms like arXiv and combines theoretical insights with practical applications in areas such as foundation models and explainable AI. I also gained industry experience as a data science intern at BASF SE, where I developed predictive maintenance models for chemical production processes.

I am fluent in German and English, proficient in programming languages such as Python, C++, and CUDA, and experienced with machine learning frameworks like PyTorch, TensorFlow, and Huggingface. Beyond my technical work, I have held leadership roles, including serving as a board member of the Engineering Association at ETH and as president of the LSE Bankside House Committee.

Master Thesis: Meta-Learning within the PAC-Bayesian Framework
This master thesis delves into the exploration of Meta-Learning through a PAC-Bayesian lens, introducing the PACOH algorithm as a new class of meta-learners with probabilistic performance guarantees. It bridges the gap between empirical success and theoretical foundations in Meta-Learning, offering a comprehensive analysis and numerical experiments to demonstrate the efficacy of these approaches.

Bachelor Thesis: A Numerical Analysis of Zero-Dimensional Fabry-Pérot Micro-Cavities
This Bachelor Thesis presents a numerical analysis of zero-dimensional Fabry-Pérot micro-cavities, emphasizing the impact of integrating hexagonal Boron Nitride (hBN) freeforms to manipulate electric field distributions. Through the development and application of numerical models, the study explores the effects of various hBN lens shapes and configurations within Fabry-Pérot cavities, revealing significant insights into the dependence of transverse confinement on lens curvature and the behavior introduced by multiple lenses. This research contributes to the understanding of optical micro-cavities and lays the groundwork for further exploration of arbitrary hBN shapes in optical device engineering.

GPU-based Real-time Data Processing for Ultrafast Laser Applications
This project explores the development and implementation of a real-time data processing system using the Spectrum M4i.4420-x8 digitizer card and SCAPP framework to enhance data acquisition in ultrafast laser experiments. By leveraging the computational power of GPUs, the system processes large data volumes from high-resolution spectroscopy and rapid pump-probe measurements more efficiently than traditional methods. The study demonstrates significant improvements in flexibility and data processing speed, offering a new approach to handling the demanding data analysis requirements of cutting-edge laser research.

Analysis II Exam Preparation Course: Multivariable Calculus
This document outlines the Analysis II exam preparation course conducted by Klemens Flöge for Prof. Tristan Rivière’s class in the Spring semester of 2021. The course, delivered in German, aimed to deepen students’ understanding of multivariable calculus, covering topics such as topology, differential calculus in multiple dimensions, optimization, implicit functions and diffeomorphisms, multiple integrals, and major integral theorems like Green’s, Gauss’s, and Stokes’s theorem. The script reflects an effort to bring theoretical concepts closer to students, fostering intuition in Analysis.
