Research Interests
My research is dedicated to understanding and addressing the disproportionate impact of traffic-related air pollution on historically marginalized populations in urban environments. This work employs high-resolution chemical transport models to evaluate the effectiveness of policy interventions, such as zero-emission vehicles, in improving public health and reducing racial and ethnic disparities in air pollution exposure. I also work on improving the representation of traffic-related emissions, particularly those associated with freight transport, within regulatory models. My goal is to leverage this research to better inform real-life policies to advocate for healthier, more equitable air quality in urban environments and advance issues of environmental justice.
