About

I am a PhD student at the Max Planck Institute for Software Systems. My advisor is Krishna P. Gummadi.

My research interests are in the area of fairness in Machine Learning as well as understanding the effects of algorithmic decision making and digitalization on society.

I pursued my undergraduate studies in computer science at Saarland University.
