Personal profile
Short presentation
I am a sociologist who studies how international immigration is transforming societies. I am particularly interested in how contemporary democracies grapple with ethno-racial diversity and how they navigate the challenge of fostering social cohesion and solidarity that transcend ethnic boundaries. My work draws on diverse social theories and research methods to gain insights on challenges to equality and social cohesion in an increasingly diverse world. Currently, I study citizens’ clashing views on the definition and prevalence of ethno-racial discrimination using field-, survey, and game-behavioral experiments.
My office hour is Tuesdays 10-11am in office 16.1.93.
Teaching
At KU's Department of Sociology I am teaching statistical methods, courses on race, ethnicity and discrimination, and theory-oriented introductions to Sociology. Currently I teach:
- Multiple Regression and Fundamentals of Causal Inference
- Sociolodgy of Discrimination
