Geir Drage Berentsen received his PhD in statistics from the University of Bergen in 2013 on a dissertation concerning the modelling and measurement of nonlinear dependence between random variables. In 2013 – 2016 he worked as a consultant in Safetec Nordic AS, a company that supplies a wide range of risk management services. He then returned to the Department of Mathematics working as a postdoctor.
He is now an Assistant Professor at NHH, and his research interests include count time series, longitudinal data and spatial models with applications in finance, medicine and econometrics.
