Current PhD Students

Praveen Siluvai Antony - 250x250

Name: Praveen Siluvai Antony
Supervisor(s): Dr. Daniel Posen
Current Work: My PhD research broadly focuses on biofuels and public policies. In my first project, I developed a supply chain model for Sustainable Aviation Fuel (SAF) from canola and estimated Canada’s near-term SAF potential. Specifically, I estimated the number of SAF plants that can be constructed, identified optimal locations, and quantified the life cycle carbon footprint of SAF supplied to the airports. In my current research, I focus on understanding the nature of changes in the carbon intensity of a matured technology in the market by performing a retrospective LCA using corn-ethanol from GREET as a case study.
