Post-Doctoral Fellows


Mehdi Jadidi

Dr. Mehdi Jadidi
mehdi.jadidi@ryerson.ca

Dr. Jadidi earned his PhD in Mechanical Engineering from Concordia University (Montreal, Canada) in 2016. His doctoral study on compressible reactive multiphase flows primarily concerned the understanding of physical phenomena involved in suspension thermal spray processes. Following his PhD, he studied at École Polytechnique de Montréal as a post-doctoral fellow. Then, he returned to Concordia University, where he continued his research on thermal spray processes. His research mainly focused on the design and development of liquid accelerated cold spray system. He is now a post-doctoral fellow in the Dworkin group at Toronto Metropolitan University focusing on simulation of combustion processes.


Sahar Taslimitaleghani

Dr. Sahar Taslimitaleghani

Dr. Sahar Taslimi Taleghani received her Ph.D. in mechanical engineering from the University of Sherbrooke in 2019. Her Ph.D. research was the analysis and optimization of a transcritical CO2 ejector heat pump system. Following her Ph.D., she led different collaborative projects between industry and the university. She has worked on waste heat recovery technologies through integration of cooling, heat, and power production to increase efficiency and reduce gas emissions in the industry. Her research interests are in energy efficiency technologies, heating and cooling systems, renewable and sustainable energy systems, numerical modelling, and optimization. She recently joined the Dworkin group at Toronto Metropolitan University as a post-doctoral fellow to work on a research in Sustainable Building Energy with a focus on geothermal heating and cooling.


PhD Students


Francisco Cepeda

Francisco Cepeda
fcepeda@ryerson.ca

Francisco 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. His research focused 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. He joined the Mechanical and Industrial Engineering Department at TMU/Ryerson as a Ph.D. student in 2019, focusing his research on modeling soot formation and combustion processes.


Andisheh Khanehzar

Andisheh Khanehzar
andisheh.khanehzar@ryerson.ca

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.


Masters Students


Luke Di Liddo

Luke Di Liddo
ldiliddo@ryerson.ca

Luke completed his Bachelor’s Degree in Mechanical Engineering at TMU/Ryerson University in 2020, specializing in thermofluids. His energy and passion in his undergraduate studies led him to receive the Mechanical Engineering Alumni Award in 2019. Luke’s interest in thermofluids led him to be a research assistant at TMU/Ryerson in his third and fourth years of undergraduate study, where he was honoured to receive Ryerson’s Undergraduate Research Opportunity (URO) award. He is pursuing a Masters in Applied Science focusing on modelling soot formation.


Beatrice Adebisi

Beatrice Adebisi
badebisi@ryerson.ca

Beatrice completed her Bachelor’s Degree in Mechanical Engineering at the Georgia Institute of Technology in 2018. During that time, she also pursued a minor in Industrial Design and worked on a research project developing rapid prototyping methods for people with disabilities. It was through that project she developed a passion for research. She is currently pursuing her Masters in Thermofluids at Toronto Metropolitan University, with a focus into soot modelling research.


Krystal Henry-Mathieu

Krystal Henry-Mathieu
krystal.henrymathieu@ryerson.ca

Krystal completed her Bachelor’s Degree in Environmental Science at McMaster University in 2020. During that time, she participated in sustainability competitions which further developed her passion for research. She is currently pursuing her Masters in Environmental Applied Science and Management with a focus on sustainable energy.
