About Me

I am a researcher and post-doc at the University of Hohenheim.

My research interests are centered on, among others, business cycle analysis, forecasting, and outlier detection. Currently, I am also interested in global value chains and their implications for business cycles. My great passion is programming - I love developing statistical toolboxes as well as web applications.

You can find my CV here.
