About Me

Starting from October 2025, I am working as a quantitative researcher at Richfox.

From March to September 2025, I was a PostDoc in Josef Teichmann's research group at ETH Zurich and I was teaching for the CAS ETH in Machine Learning in Finance and Insurance. I am associated with the ETH AI Center.

My work focuses on the intersection of machine learning and finance, as well as exploring fundamental research questions in machine learning through a mathematical lens.

From September 2019 until February 2025, I did my PhD studies with Prof. Josef Teichmann in D-MATH at ETH Zurich. Before, I studied mathematics at ETH Zurich (BSc and MSc) with a focus on mathematical finance, machine learning, statistics, probability theory and optimization. For my Master studies I was awarded the Willi Studer Prize 2020.

I love to spend my free time in the mountains. Some impressions can be found in the Gallery.

My CV can be found here (last update: June 16, 2025). Upon marriage, I changed my name to Florian Ofenheimer-Krach, but I still publish my work under my birth name Florian Krach.
