Associate Professor

Dr. Stephen Hubbard

University of Calgary


Research Focus

  • I am interested in clastic sedimentology and stratigraphy, including applications to the exploration and exploitation of hydrocarbons. My students and I combine numerous approaches to our work, including: (1) lithofacies and stratigraphic architecture analysis in core and outcrop, (2) paleoecologic reconstruction of ancient sedimentary environments through trace fossil analysis, (3) wireline log and 3-D seismic interpretation, (4) sequence stratigraphy, and (5) provenance studies.
