The whole of life is but a moment of time. It is our duty, therefore to use it, not to misuse it ~ Plutarch

Work Experience

University of Toronto, Southern Ontario Centre for Atmospheric Aerosol Research

Graduate Student

2014 - 2018

  • Planned and coordinated the technical aspects of an air quality mobile sampling campaign across the Greater Toronto Area in the summer, fall and winter (2015/2016).
  • Consulted with and answered technical questions from organizations such as Canadian Urban Environmental Health Research Consortium (CANUE), Institute for Clinical Evaluative Sciences, Environment and Climate Change Canada (ECCC) and Public Health Ontario.
  • Provided GIS and statistical training and mentorship to graduate students.
  • Authored technical reports and manuscripts that detailed methodology, results and recommendations to ECCC.
  • Provided GIS-based (satellite, land-use regression model, Global Environmental Multi-scale-Modelling air quality and Chemistry) monthly-average air pollution estimates from 2003 to 2014 for health risk assessment by Ryerson and Queen’s University, and SickKids epidemiological studies.



Caribbean Industrial Research Institute (CARIRI), Trinidad and Tobago

Chemical Engineer

2008 - 2014

  • Led a cross-functional team that developed the technical capability and capacity for external projects such as Technology Incubators. This included streamlining process flows, providing equipment specifications and layouts, and marketing material for transfer of technology to clients.
  • Supervised the data collection, interpretation, and documentation of the productivity for pilot-scale projects.
  • Provided training and supervision to technicians employed within the pilot-scale production.
  • Planned and coordinated technical aspects for production of renewable energies such as biogas, from the treatment of organic effluents.
  • Evaluated the technical feasibility and cost-to-benefit ratio associated with innovative products or technologies for the public and private sectors.
  • Provided scientific and technical advice for the development of proposals related to air quality and GHG verification.
  • Authored proposals and technical reports for Indoor Air Quality clients, that detailed the sampling protocol and results obtained from air quality testing.
