The Kovsie GeoTalks series was initiated in 2014 with the aim of:

  • increasing academic discourse among staff and students in the department.
  • exposing students to non-Kovsie researchers, academics, and experienced industry professionals and their work.
  • allowing the broader public access to the wonders of geology.
