Education & Research



Ph.D. Candidate, Chemical Engineering
calendar 2012 – Present

University of Toronto, Department of Chemical Engineering

Selected Courses: Air Dispersion Modeling, Environmental Pollution Prevention, Environmental Law
Thesis: (In Progress)

Vehicle emission factors were determined from high time resolution measurements made at a downtown near-road monitoring site in order to better quantify and characterize the impacts of traffic emissions in urban environments. As part of a larger collaborative pilot project with local and federal government agencies, near-road and urban background monitoring sites were deployed in Toronto and Vancouver in order to capture urban-scale air pollution dynamics as a result of anthropogenic activities.


Master of Science, Environmental Chemistry
calendar 2010 – 2012

University of Toronto, Department of Chemistry

Selected Courses: Environmental Chemistry, Atmospheric Chemistry
Thesis: Methane Fluxes at a Temperate Upland Forest in Central Ontario.

Methane and carbon dioxide fluxes were measured at Haliburton Forest and Wildlife Reserve, a mixed-managed temperate forest in Central Ontario, over a five-month remote field campaign with measurements made at 10 Hz resolution. Eddy covariance method was employed to calculate the fluxes between the atmosphere and ecosystem.


Bachelor of Science, Chemistry Honours
calendar 2005 – 2009

Carleton University, Department of Chemistry

Selected Courses: Experimental Methods in Nanotechnology, Physical Methods of Nanotechnology
Thesis: Volatile Organic Compounds in Smoke From Experimental Fires.

Studied chemistry with a focus in nanotechnology. Thesis project involved investigation of volatile organic compound (VOC) levels released during various stages and intensities of domestic fires and potential occupational exposure hazards related to toxic and/or carcinogenic volatile organics released.

Work Experience



Teaching Assistant
calendar 2010 – Present

University of Toronto, Department of Chemistry & Department of Chemical Engineering

Teaching assistant in experimental laboratories and tutorials; Physical Principles (CHM139); Introduction to Analytical Chemistry (CHM217); Environmental Chemistry (CHE230); Applied Chemistry III (CHE204).


Research Assistant
calendar 2006 – 2009

National Research Council of Canada (NRC)

Designed sampling technique for quantitatively analyzing volatile organic compounds in various air samples collected in small canisters, which included smoke from full scale experimental fires conducted at the NRC National Fire Laboratory and from human alveolar breath of smokers and firefighters. Analysis was done using gas chromatography/mass spectrometry (GC/MS). Semi-quantitative method and NIST mass spectral library used to identify chromatographic peaks present in historical database of arson and accelerant samples. Work eventually led to honours thesis project.
