Research Profile

My goal is to understand and improve the sustainable movement of people in cities. My research focus includes fundamental mathematical modelling of transit systems, urban rail transit optimization and analytics, data analysis and visualization, emerging technologies such as demand-responsive transit and automated vehicles.

Throughout my research process, I am to analyse and visualize the impacts of potential improvements or changes using interactive data visualization techniques. With a focus on equity and access to sustainable mobility, I hope to bridge the gap between fundamental analytical modelling and the impacts that resulting changes can have on individuals.

Research Experience

2020 - Present

Postdoctoral Fellow

University of Toronto, Toronto, ON

Supervisor: Professor Amer Shalaby


NSERC and Mitacs Postdoctoral Fellow studying urban rail performance and emerging technologies. As part of the newly founded Transit Analytics Lab, I have partnered with the Ontario Society of Professional Engineers to study demand-responsive transit in Canada, and am collaborating with Metrolinx to study passenger rail performance, modelling, and delay analysis.

2014 - 2018

Graduate Researcher

University of Calgary, Calgary, AB

Supervisor: S. Chan Wirasinghe


In addition to thesis work, I developed mathematical models of light rail transit and airport departure lounges sensitive to crowding and passenger flow effects.

May 2011 - April 2013

Undergraduate Research Assistant

University of Guelph, Guelph, ON

Supervisor: Professor Ralf Gellert


Dr. Gellert is the principal investigator of the APXS instrument on baord the Mars Exploration Rovers Spirit and Opportunity, and the Mars Science Laboratory Curiosity. In addition to my responsibilities setting up and maintaining a database to store, manage, and access calibration data for the APXS, I developed custom data analysis tools to allow team members to quickly view and analyze raw data from the lab and from Mars.

Relevant Professional Experience

August 2018 - September 2019

Research Consultant

Klumpentown Consulting, Toronto, ON


As part of team working with TransitCenter (a major American public transit advocacy organization) to create an equity-focused accessibility analysis of major US cities, I developed an interactive web visualization platform to allow advocates and the public to view and share the results of this analysis. This included a geopsatial visualization of hundreds of combinations of measures and parameters, interactive and udpating charts, and a temporal component which allows users to view how transit agencies' responses to the Coronavirus pandemic has affected service, access, and equity.

August 2018 - September 2019

Planner & Senior Policy Advisor

Ministry of Transportation Ontario, Toronto, ON


Starting as a planner in the Systems Analysis and Forecasting office, I developed geospatial analysis tools for large datasets, including truck positioning data, commercial vehicle survey data, and the Transportation Tomorrow Survey. This analysis supported the Southwestern and Eastern Ontario Regional Needs Assessment projects, and supported the development and implementation of a provice-wide passenger and freight transportaiton model.

At the Strategic Transit Investments Office, I coordinated the launch of the annual provincial gas tax pogram which provides operational transit funding to Ontario municipalities, supported the development of funding agreements for large transit projects with Ontario municipalities, and advised on future procurement and policy related to the administration of the gas tax program.

December 2013 - April 2014

Rail Traffic Controller

Canadian Pacific, Calgary, AB


Responsive for the safe and efficient movement of trains on the Canadian Pacific rail network. Required qualification in the Canadian Rail Operating Rules and a strong understanding of Canadian heavy rail operations.
