I'm a Data Science Consultant at Statworx where I lead the Natural Language Processing cluster.
Previously, I was a PhD fellow at the joint Economics doctoral program of Humboldt University Berlin, Free University Berlin, Technical University Berlin, ESMT Berlin, and WZB.
I remain a visiting researcher at ESMT Berlin.
I am interested in Deep Learning, Graph Neural Networks, NLP, Network Science and Causality.
