Post-Doctoral Fellows

Francisco Cepeda

Francisco Cepeda

Dr. Francisco Cepeda completed his bachelor’s degree in Industrial Engineering at Universidad Técnica Federico Santa María, followed by his MSc. degree at the same university in 2017. He completed his PhD at Toronto Metropolitan University in 2023. His research focuses on understanding how the soot formation and oxidation processes of non-premixed flames are affected by introducing changes in the combustion conditions, such as the oxidizer composition, and by imposing forced oscillations in the fuel stream.


Mohammadamin Ahmadfard

Dr. Mohammadamin Ahmadfard is a Mechanical Engineering PhD graduate from Polytechnique Montreal, where he specialized in renewable energies with a focus on geothermal science under the supervision of Prof. Michel Bernier. With several years of experience, Mohammadamin has a strong background in designing HVAC systems incorporating heat pumps connected to solar panels and borehole thermal energy storage. His expertise also includes designing boreholes, problem optimization, simulating analytical and numerical models, and fluid and heat transfer.

PhD Students

Andisheh Khanehzar

Andisheh Khanehzar

Andisheh completed her Bachelor’s Degree in Mechanical Engineering at Shiraz University in 2015 and her Master’s Degree in Aerospace Engineering at Sharif University of Technology in 2018. In her M.Sc. thesis, she worked on the numerical investigation of MILD combustion enhancement through plasma injection. She was honoured with the 2020 Best Thesis Award of the Iranian Aerospace Society. Currently, she is pursuing her PhD studies in combustion simulation, with a focus on soot modelling and prediction.

Ibrahim Ghalayini

Ibrahim Ghalayini

Ibrahim completed his bachelor’s and MASc degrees in Mechanical Engineering at Toronto Metropolitan University in 2020 and 2021, respectively. His research focused on numerically modelling nanofluids and investigating single-phase and two-phase models. Due to the effects of nanoparticle sedimentation on heat extraction, his thesis focused on employing Buongiorno’s two-phase model to develop an understanding on the effects of Brownian motion as well as thermophoretic effects on the hydrothermal properties of nanofluids. He re-joined the Mechanical/Industrial Engineering Department at Toronto Metropolitan University as a PhD student in 2022, focusing his research on numerically modelling ground source heat pump systems in steel helical piles.

Masters Students

Anthony Di Liddo

Anthony Di Liddo

Anthony achieved his Bachelor’s degree in Mechanical Engineering from Toronto Metropolitan University in 2023. Throughout his undergraduate studies, he actively participated in a range of courses and projects that revolved around fluid mechanics and heat transfer, further fuelling his passion in the field. Serving as an undergraduate research assistant within the Dworkin group, he made valuable contributions to the domain of sustainable building energy research. Currently, Anthony is pursuing a Master of Applied Science degree in Mechanical Engineering, with his research focusing on developing an advanced geothermal heating and cooling control system for optimization.
