Research Interests

My research interests include:

  • Concept for a general theory of measuring diversity among populations.
  • Development of general strategy and logically consistent approaches for analyzing structure of populations with an asexual or mixed mode of  reproduction for different types of organisms and markers.
  • Development of computational tools for diversity analysis (in particular, for populations of plant pathogens and their hosts).
  • Analysis of different host-pathogen systems.
  • Modeling of plant pathogen epidemics.
