Professional Experience

Prior to NIBIO I worked as Postdoctoral Research Associate at Oregon State University, USA (2005-2006) and Göttingen University, Germany (2007), as Lecturer at Freiburg University, Germany (2007-2013), and as Research Associate at the University of Maine, USA (2013-2020).
My research activities have covered the silvicultural manipulation of regeneration and growth dynamics of mixed species forests, limitations of the close-to-nature forest management paradigm in Central Europe, the ecology and silviculture of oak forests, the quantification of forest structural heterogeneity and analyzing its effect on stand- and tree-level growth, as well as modeling the influence of alternative forest management practices on stand dynamics and forest regeneration patterns.
