Brief profile:


I studied engineering and business administration at the "Politehnica" University in Bucharest and graduated in 2000 as best of my class. After a brief period at the Technical University in Darmstadt as a research and teaching assistant, I started to work on my PhD under the supervision of Uwe Hassler at the Goethe University in Frankfurt. 

In 2005, I obtained my PhD in econom(etr)ics; the PhD thesis consists of four papers dealing with misspecifications in models with seasonal deterministics and issues in forecasting under asymmetric loss functions. Having chosen to pursue an academic career, I went on as a post-doc researcher in Frankfurt. My research during this period focussed on (non)stationary panels with cross-unit dependence. 

During the academic year 2007-2008, I was a Max Weber fellow at the European University Institute in Florence. My mentor during the stay in Tuscany was Helmut Lütkepohl. In summer 2008, I returned to Frankfurt on a position as junior professor for applied econometrics, and moved to the University of Bonn in 2010, where I was a professor at the Hausdorff Center for Mathematics. I joined the University of Kiel in April 2014. In Kiel, the focus of my research has moved towards forecasting.


I believe a student's understanding of applied statistics and econometrics can benefit a lot from treating econometric models and methods with mathematical rigor. Please consult the teaching section for more details on specific courses; see above for courses I'm teaching this semester.

Research focuses

Forecasting, long memory and persistence, panel data with cross-sectional dependence. While my research interests lie mainly with the development of econometric methods, I try to apply them meaningfully to real-world problems.
