About me

I'm currently involved in both methodologic and applied research. My methodologic research is primarily concerned with methods for causal inference in observational studies, methods for analyzing sibling (e.g. twin) data, and methods for doubly robust estimation. I'm giving statistical support to applied researchers in various fields, such as genetic epidemiology and nutritional epidemiology.

Education

  • 2002 MSc in Electrical Engineering from Royal Institute of Technology in Stockholm
  • 2004 MSc in Statistics from Stockholm University
  • 2009 PhD in Biostatistics from Karolinska Institutet in Stockholm
