Here you will find information about Research groups in the PathoGenoMics fields from the ERA-NET partner countries (Austria, Finland, France, Hungary, Israel, Latvia, Portugal, Slovenia and Spain).
This information is supposed to support cooperation between researchers from different European countries
and thus enhance the development of a European Research Area for PathoGenoMics .


The following information is available and can be searched for:

  • researcher names
  • Institution of the respective researcher, city and country of his/her institution
  • Contact data of the researcher (address, phone, email)
  • Research topics and studied microorganisms of the researcher
  • Special techniques applied by the researcher
  • Potential cooperation topics suggested by the researcher
