OEH Seminar: Can we improve air pollution estimates when extending land-use regression models to adjacent cities or backward in time?

Land-use regression models can be used to estimate traffic-related air pollution (TRAP) at a fine resolution. This makes these models a useful tool for assessing if a relationship exists between specific TRAP and the development of adverse health outcomes such as dementia.
While these models are commonly used in epidemiological studies, the traditional way that these models are developed has inherent limitations, that can lead to exposure misclassification. In this seminar, we will learn about these limitations and discuss the research that is being done to improve these model estimates when extending these models to adjacent cities and backward in time. 

Presenter: Dr. Kerolyn Shairsingh

Kerolyn Shairsingh received her BASc. in Chemical Engineering and Applied Chemistry from the University of Toronto in 2008. After which she worked as a chemical engineer at the Caribbean Industrial Research Institute in Trinidad and Tobago, from 2008 to 2014. In 2013 she obtained her MSc. in Chemical and Process Engineering from the University of the West Indies. Her Ph.D research at the University of Toronto focussed on improving land-use regression model estimates of traffic-related air pollution when extending these models over space and time. Currently she is developing Greater Toronto Area land-use regression models for use in future epidemiological studies.
