Since May 2023, I work as a Database System Engineer at RelationalAI.
Previously, I was a Research Associate and PhD candidate
in the Database Systems and Information Management (DIMA) group at Technische Universität Berlin,
working on efficient large-scale machine learning. I was supervised by Volker Markl and Rainer Gemulla.
Prior to that, I completed a M. Sc. Business Informatics with a specialization in Data and Web Science
at Universität Mannheim,
with a semester at VU Amsterdam (with courses from CWI).
In my Master's thesis, I worked on scalable sequential pattern mining,
supervised by Rainer Gemulla
and Kaustubh Beedkar
I obtained my B. Sc. in a dual program at DHBW Mannheim with a semester at Universidad Carlos III Madrid. In this program, I worked for HP in Germany and the U.S.

Different aspects of research activity contribute to the climate crisis. One is long-distance travel. Thus, I try to limit travel.
Like others, I think it is reasonable that academics report the climate impact of their work. As a step in this direction, please find below a list of flights I have taken during my time in academia.

Talk at ECNU Shanghai

The CO2 emission estimates are taken from atmosfair. If you have tips on how to estimate other emissions of research (e.g., computer and cluster usage, office construction and heating), please let me know.
