Welcome!

I am an Assistant Professor at the University of Southampton since January 2023. 

Before that, I was a Postdoctoral researcher at the University of Surrey. I completed a PhD In Economics at the University of Regensburg in 2021 in the graduate school Evidence-Based Economics (joint with LMU Munich). 

In my research, I apply and develop machine learning methods to address problems of causal inference in labor economics.
