About Me
I am a tenure track Assistant Professor (W1) of Econometrics and Statistics at the Institute of Finance and Statistics at the Department of Economics at the University of Bonn.
I hold a PhD in econometrics from Universitat Pompeu Fabra, Barcelona.
Research
Research interests: I am interested in developing practical statistical methods with a focus on unobserved heterogeneity.
Why should we care? Unobserved heterogeneity is pervasive in economics and business:
- Heterogeneous treatment effects and other parameters
- Explanatory variables not captured by data
- Unobserved “fundamental” characteristics of agents
- Measurement error
Ignoring this heterogeneity in non-experimental settings may lead to crippling bias and invalid inference. Accordingly, we need methods that can handle this issue.
Blog
I occasionally blog about data, statistics, and programming. Check out some recent posts:
