Roles and responsibilities
- As President’s Science Advisor and as Secretary, President’s Research Excellence Advisory Committee (PREAC), provide leadership, advice, and guidance on a wide range of topics related to research excellence at NRC.
- As Principal Research Officer, engage in multidisciplinary science with both experiments and numerical simulation covering research, development, and application of optical diagnostic techniques in combustion systems and for black carbon; nanoparticle formation; nanoparticle characterization; and particulate and black carbon emissions.
- Serve as an ambassador for nanotechnology and combustion science, raising awareness of recent advances, participating in international standardization committees, and providing technical insights to the policy and regulatory fields of air, marine, and ground transportation.
Current research and/or projects
-
Addressing environmental metrology through the development of black carbon measurement science, articulating the challenges and promising approaches to regulators and policymakers dealing with climate change, air quality, health, emissions of black carbon, and atmospheric monitoring.
-
Supporting nanotechnology in Canada and internationally with SCC and ISO/TC229 standards development and with support for NanoCanada through networking and foreign missions.
Research and/or project statements
- Investigating issues surrounding quantitative measurements of black carbon (BC) nanoparticles, including physical and chemical properties of black carbon, surface contaminants, and co-emitted species that may affect the uncertainty associated with the measurement.
- Developing a detailed understanding of the underlying physical principles behind many black carbon measurement instruments to aid in interpreting differences in response of instruments to identical sources of BC
- Developing sources and methods for calibration of instruments to measure mass concentration of black carbon nanoaerosols, with application to emissions from ground, air, and marine sources as well as atmospheric environmental measurements.
- Leading a project with Transport Canada regarding regulatory and technical development research on nonvolatile particulate matter (nvPM) and black carbon emissions from civil aviation gas turbine engines
- With a successful NRC-Germany Call for Project Development Proposal, leading a project exploring measurement science for gas phase graphene synthesis between NRC and the University of Duisburg-Essen (UDE)

Inventions and patents
- Two patents were licensed in 2000 to Artium Technologies, Inc. for “Method and Apparatus for Applying Laser-Induced Incandescence for the Determination of Particulate Measurements”. Artium has produced two instruments based on the licensed technology, the LII 200 and the LII 300. The license was renewed in 2010, and Artium continues to achieve commercial success in producing these instruments.
