Current research and/or projects

I am the Director of the Canadian Geodetic Survey, Surveyor General Branch, NRCan and chief geodesist of Canada.

Research and/or project statements

- As Director of the Canadian Geodetic survey I provide direction to Canada's geodetic agency.


- As Acting Director for the NRCan Office of the Chief Scientist (2014) I managed a team of 14 staff, supporting the Chief Scientist in providing leadership across the Federal Government in policy for science.

- As Section Chief for Geodetic Systems and Infrastructure (2010-2015) I managed a team of approximately 16 staff involved in Global Navigation Satellite System (GNSS) network operations and client support. I was the Liaison for scientific applications of Geodesy and remain involved in research in applications of Geodesy for water quantity studies. I supported NRCan's involvement in the Federal GNSS Coordination Board. In particular I supported efforts related to GNSS sensitivity to Space Weather.

- As Assistant to the Chief Scientist of the Earth Science Sector (2005-2006), I assisted with the preparation of files related to science strategy and research, providing strategic advice to senior management.

- As Program Manager of the Reducing Risks from Natural Hazards (Public Safety Geosciences) program (2008-2010), I provided oversight and management of the research activities of a large interdisciplinary, national team. I managed program finances and supervised project leaders involved in earthquake, tsunami, landslide, space weather and volcano hazard assessment.

- As a Research Scientist (1997-2001) I played a key role in developing a Canadian astronomical geodesy program.

Professional activities / interests

- Global Navigation Satellite Systems - operations today and future position and navigation capabilities.

- Economic analysis of geoscience products, information and services.

- Scientific applications of geophysics.

- Science-Policy linkages, communications.
