Research Scientist

Research in glacial landscape evolution of northern Canada, to improve mineral exploration success

Natural Resources Canada

Current research and/or projects

Activity leader for surficial mapping of the GEM2 Hudson-Ungava Project (2014-2017). Current research includes mapping the surficial geology and unravelling the glacial history of a region that is underexplored, yet prospective for potential mineral deposits and development in northern Canada.  

Professional activities / interests

  • GEM1 project leader in establishing field protocols for sampling of surficial sediments in the field, sample processing and establishing QA/QC measures. Protocol compilation also included publication of field safety practices.
  • Train the next generation of surficial geologists in Canada, through logistical support, co-supervision and mentoring of graduate students.
  • Active research in our understanding of glacial dispersal of minerals with fast-flowing ice (ice streams).
  • Collaborate and combine research interests with academia (universities).
