Researcher in the
at TU Berlin.
Since September 2017, I am a Research Associate and a PhD candidate
in the Database Systems and Information Management (DIMA) group at Technische Universität Berlin,
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.
My current research interest is in large scale machine learning.

I was accepted into the Software Campus program, so that the BMBF provides additional funding for my PhD research. If you are a TU student interested in large-scale machine learning, feel free to send me an email.
My M.Sc. faculty honored my master's degree (best 2016/17 degree) and master's thesis (best 2016/17 thesis)

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 we report the climate impact of our work. As a step in this direction, please find below a list of flights I have taken so far.

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