Research Interests

Urban Air Pollution

SOCAAR’s Mobile Analysis of ParticuLate in the Environment (MAPLE) “lab on wheels” can measure spatial and temporal variations of ambient aerosol characteristics.

My research examines air pollution using advanced instrumentation and data mining. Our goal is to make key connections between emissions of pollutants, the quality and composition of urban air, and the impacts on human health and the environment. Focus areas include traffic related air pollution, Identifying the sources of pollution, development of inexpensive sensors, and understanding how the sources and composition of particulate matters influences its potential to induce oxidative stress. Most of my research is executed through the Southern Ontario Centre for Atmospheric Aerosol Research (SOCAAR). SOCAAR is an interdisciplinary centre for the study of air quality, with a focus on how aerosol particles impact human health and the environment.

Engineering Education

As the Director of the Institute for Studies in Transdisciplinary Engineering Education and Practice (ISTEP) and the Collaborative Specialization in Engineering Education (EngEd), I am also very interested in the scholarship of teaching and learning. ISTEP is a new department with 11 faculty that is taking a deeper look at what we teach engineering students, what they will do after they graduate, and how they learn the competencies and skills that will help them enjoy successful careers and bring benefits to society. The EngEd is a collaborative learning community that brings together graduate students from UofT’s Faculties of Engineering and Education. I am currently pursuing research related to the instructions of transdisciplinary competencies, metacognition, lab-based-learning, lifelong skills development, and mining student data to create richer holistic pictures on student leaning experiences.
