I am an environmental analytical scientist with a strong background in statistical treatment of data. I have significant field experience in developing and deploying analytical instrumentation in the High Arctic and low cost instrumentation in urban environments.
My current research at Concordia University in Montreal, Canada focuses on long-term observations of urban pollutants in Montreal and major Canadian cities. I am interested in statistical analysis of medium sized data sets, including multivariate data analysis of partially dichotomous data and interpreting measurement data for the application and validation of atmospheric chemistry models. My main statistical tools for data analysis are python and R.
I develop field deployable sensors to track urban air pollution, with a focus on critical air pollutants and organics. The goal is to determine local pollution sources and transport and accurately measure actual exposure levels in real-time. Recently, I was part of the Decolonizing Light project that develops and deploys a community-science low-cost sensor air quality monitoring network in collaboration with the community of Kahnawà:ke. Collaborations that evolved from my participation in Decolonizing Light are still ongoing.
