About Me

Hi there! Welcome to my site!

I recently completed my PhD. The focus of my thesis is on data management issues for the future Industrial Internet of Things. If you want to know more, head over to the research section.

During my PhD became a member in the Software Campus, a German program that supports PhD with a 2-year leadership programme. As member of the Berlin Big Data Center (BBDC) project I studied the performance of Apache Flink for straggling tasks. I also organized an introduction to programming course with ~800 students.
