About Me
I am a researcher and lecturer at the University of Vienna, affiliated with the Wittgenstein Centre for Demography and Global Human Capital. My research explores how biological factors such as stress, health, and fecundity interact with social relationships, environments, and institutions to shape family formation and reproductive behaviour. By bringing together different kinds of data and combining individual- and societal-level perspectives, I aim to better understand why birth rates are changing and how policies can support people in achieving their reproductive goals.

In this seminar, I guide students through the foundations of applied empirical research in the social sciences, from understanding data sources to applying key microeconometric methods. The focus is on developing both technical competence and the ability to critically assess research design and evidence.
