Dr. Coniglio's research focused on the chemical and physical changes that occur when carbonate sediments turn into limestone and dolomite. He has been involved in research projects across Canada, as well as in the Caribbean, South America, Egypt, Oman, Iran, Italy, and the United States.

Dr. Coniglio served as Associate Vice-President, Academic from 2013 to 2019.

Research Interests

  • Geological processes of sedimentation and diagensis (the chemical and physical changes that occur as sediments solidify)
  • Carbonate deposits in the Ordovician, Silurian and Devonian sequences of Southern Ontario

Scholarly Research

Dr. Coniglio's research focused on sedimentation and diagenesis of carbonate rocks in the Ordovician, Silurian and Devonian sequences of southern Ontario. Interests included physical and chemical aspects of shallow and deep burial diagenesis and porosity development in dolomitized hydrocarbon reservoirs and groundwater aquifers. Please note that Dr. Coniglio is not accepting graduate students nor providing opportunities for supervision of internships.
