Prior to becoming a secondary school teacher and during my years as a post-secondary student, I worked at a variety of research institutions, including the York Observatory, the Queen's University Astronomy Research Group, Chalk River Laboratory, and Defense Research Establishment Valcartier. While working at these institutions I was involved with a variety of projects ranging from variable star and globular cluster system studies, materials engineering, and computer modeling.

I was also deeply involved in the public outreach programs at the York and Queen's observatories, guiding tours and discussing various astronomical topics with members of the public.

I earned my undergraduate degree at York University where I majored in physics, specializing in astronomy. I earned my bachelor of education from Trent University.

I am a qualified intermediate/senior mathematics and science (physics) teacher.

I have taught science and mathematics at St. Lawrence Intermediate and Secondary School since 2004. I spent a brief period from October 2010 to June 2011 teaching at Cornwall Collegiate & Vocational School.

I have been a staff supervisor/coach for many types of extra-curricular activities, including but not limited to:

  • SET Club (Science Engineering Technology)
  • School Reach Team
  • Stage/Tech Crew
  • SLIS Bear Pawpaganda Radio
  • Midget Girls Volleyball

Since 2010 I have been the School Reach Regional Coordinator.

I am a member of the United Counties Science Fair Committee currently serving at the Chair. I have served as Vice-Chair and Facilities Coordinator. I have also chaperoned our regions Finalists to the Canada Wide Science Fairs in Vancouver, BC (2005), Sanguaney, QC (2006), Truro, NS (2007), Ottawa, ON (2008), Peterborough, ON (2010), and Toronto, ON (2011).

I am a mentor on the NGS Tech Tigers First Lego Robotics Team which meets every Saturday in Maxville.
