Counterterrorism expert Ed Waller, PhD, has dedicated his career to protecting the safety and security of Canadians by innovating ways to reduce the threat of radiation exposure from nuclear disaster. One of the world’s leading radiation experts, he is a Professor in the Faculty of Energy Systems and Nuclear Science, and has been a Natural Sciences and Engineering and Research Council of Canada (NSERC) and University Network of Excellence in Nuclear Engineering (UNENE ) Industrial Research Chair in Health Physics and Environmental Safety since 2008. His research focuses on nuclear safety, security and safeguards to secure nuclear radiation sources including counterterrorism measures, emergency response and environmental effects associated with nuclear power plants in Canada. In the area of health physics, Dr. Waller conducts risk-based analyses of radiation exposure and investigates ways to ensure exposure is as low as reasonably achievable. Environmentally, his research also explores the impact of low doses of radiation on non-human species. A prominent five-year delegate with the NATO working group investigating radiation bioeffects and countermeasures, Dr. Waller has been researching radiological dispersal devices and their effects for more than 15 years. He developed a novel Radiation Triage Mask to rapidly identify and assist with treatment strategies for those who have been exposed internally to radioactive isotopes generated by dirty bombs. The patented RTM determines the type of exposure and amount inhaled, providing first responders the ability to quickly establish a course of treatment and save lives. Globally, Dr. Waller is part of a research team to design a novel sensor for an improved landmine detection system, an invention that is currently being used in countries where landmines are prevalent. Notably, he is the first Canadian academia delegate appointed to United Nations Scientific Committee on the Effects of Atomic Radiation, and works closely with the International Atomic Energy Agency (IAEA). He joined Ontario Tech University in 2003 as Associate Professor, was appointed Professor in 2009 and named Associate Dean of Graduate Studies in 2011. In 2015, Dr. Waller served as Dean of Graduate Studies, then Dean of the Faculty. Previously, he spent 15 years with Science Applications International Corporation dealing with threat assessment, health physics and applications of radiation.
