introduction

I am a probabilist with research interests that span a wide range of random spatial processes. I am particularly interested in percolation processes, spatial growth models, aspects of competing growth, combinatorial optimization problems, and analysis of Boolean function.

Since 04/2017 I am based at Stockholm University (tenured 01/2022). I obtained a Ph.D. at the University of Gothenburg (09/2011), supervised by Professor Olle Häggström.
Before coming to Stockholm I was a postdoctoral researcher at MSRI in Berkeley during a semester-long programme on random spatial processes, at IMPA in Rio de Janeiro, and at Uppsala University.

Research in part supported by the Swedish Research Council (VR) and the Ruth and Nils Stenbäck Foundation.

A list of publications can be found below. For citations, statistics, etc., see

miscellaneous

Students looking for a PhD position, or a postdoc, in discrete probability theory are welcome to get in contact.

educational material

Below you will find some material intended as a companion for undergraduate students interested in probability theory. The written material are serve as an illustration of the use of probabilistic techniques in a specific problem. The video tutorials provide an overview of basic concepts in probability theory and the theory of Markov chain mixing.
