Research interests

Marius Hofert's research interests are Computational Statistics and Data Science (data visualization, parallel computing, software development in R), Dependence Modeling with Copulas (high dimensional problems, hierarchical models, random number generation, computational aspects, graphical approaches) and Quantitative Risk Management (risk aggregation, risk measures, computational challenges).  Furthermore, he is an active developer, contributor and maintainer of statistical software in R.

Education/biography

After completing a diploma in Mathematics and Management at University of Ulm and a masters degree in Mathematics at Syracuse University, Marius Hofert obtained his PhD in Mathematics from University of Ulm in 2010. He then held a postdoctoral research position (Willis Research Fellow) at RiskLab, ETH Zurich, under the supervision of Professor Paul Embrechts. After a guest professorship (W2) in the Department of Mathematics at Technische Universität München and a visiting assistant professorship in the Department of Applied Mathematics at University of Washington, he joined the Department of Statistics and Actuarial Science at University of Waterloo in July 2014.
