Personal and Professional Bio

Originally from Ottawa, Ontario, Dr. Heffernan received his Ph.D. from the Royal Military College (RMC) of Canada in Kingston in 1997.  He served as an officer with the Canadian Military Engineers from 1982 until 2005.  He worked as a lecturer and Assistant Professor of Civil Engineering at RMC from 1994 until 1997.  After serving as the Officer Commanding of the Engineering Squadron and Deputy Commanding Officer at 1 Construction Engineering Unit (1 CEU (now 1 ESU)) he returned to RMC in 2001 where he was cross-appointed to the Mechanical and Civil Engineering Departments.  In 2002 he was appointed as Chair of the inter-departmental programme Master of Defence Engineering and Management and in 2010 was appointed as the Head of the Civil Engineering Department.  In 2014 he was appointed as the Vice-Principal, Research and Dean of Graduate Studies.

Research Interests

Dr. Heffernan has an active research program which deals predominantly with extreme loading, resilient design for critical infrastructure, rehabilitation and fatigue of structures.  Dr. Heffernan’s research is applicable to both military and civilian agencies that are interested in vulnerability evaluation, blast resistance and damaged structural assessment and repair. 

  • Assessment, analysis, and strengthening of blast damaged structures
  • Resilience of Critical Infrastructure
  • Vulnerability assessment
  • Post-strengthening of damaged bridges and structures using fibre-reinforced polymers (FRP)
  • Fatigue performance of reinforced concrete beams
  • Fatigue performance of reinforcing steels in lab air and corrosive environments
  • Fatigue performance of various aircraft alloys and structural systems.

Statement of Teaching Philosophy

My teaching philosophy is rooted in the inquisitive nature of the students and their desire to learn. While I believe the responsibility to learn rests solely with the student, there is much we as teachers can do to facilitate and excite their learning experience. As a teacher of technical content, the methods used must be connected to both the material being delivered as well as the students learning styles. My experience has led me to focus on learning from first principles through engagement and critical analysis.  A found understanding of the theory must be backed up with rigorous practice through problem solution.  Solutions should both reflect and extend the applications covered in class.

Primary Teaching Areas

  • Critical Infrastructure and resilient design
  • Mechanics of materials
  • Structural Analysis
  • Reinforced Concrete Design
  • Repair and rehabilitation
