About me

I obtained my PhD in Statistics in 2015 in a cotutelle between the University of Geneva and the University of Sydney. I then worked as a post-doctoral fellow at Dalhousie University as part of a Canadian Statistical Sciences Institute collaborative research team. I was an Assistant Professor of Statistics and Coordinator of the MS in Data Science in the Department of Mathematical Sciences at Stevens Institute of Technology before joining the Swiss Data Science Center, affiliated with ETH Zurich, in 2020 as Senior Data Scientist.

My research interests lie in robust statistics, semi-parametric methods, computational statistics, and spatio-temporal modeling with ecological applications. My current methodological research includes robust smoothing parameter selection for non-parametric additive models and implementations of outlier detection for general state space models. Ongoing cross-disciplinary collaborations include growth estimation methods from mark-recapture data and large-scale spatio-temporal modeling of the impact of volcanic eruptions on vegetation density from satellite imagery.
