Short CV

I joined the University of Zurich on November 1, 2007. During 1997-2001 I studied mathematical statistics and actuarial science at the University of Bern, with several short stop-overs at UBS. From 2002-2006 I then worked on my PhD under the supervision of Prof. L. Dümbgen, entitled "Log-concave density estimation and bump hunting for i.i.d. observations". Besides that I held a 40% position as a biostatistician at the Swiss Institute for Applied Cancer Research SAKK in Bern. A SNF grant for prospective researchers then offered me the opportunity to work one year as a postdoctoral scholar in the statistics department at Stanford University.
