Dr Pavel Krivitsky

  • 2009 PhD in Statistics University of Washington, Seattle, WA, USA
  • 2006 MS in Statistics University of Washington, Seattle, WA, USA

Science
School of Mathematics & Statistics

I develop methods and models for analysing complex network data and processes with applications in epidemiology and the social sciences. I am particularly interested in unusual or indirectly observed or sampled network data. My work has a strong computational component, and I develop and maintain a number of popular R packages on CRAN.
