“The Effect of Initial Air Content on the Performance of Electrical Resistance Heating: a Numerical Modeling Study”

Reza Rahimi is a 2nd-year Ph.D. Candidate at the Department of Civil Engineering at York University. His background includes two years of industrial jobs and four years of research as a petroleum engineer before starting his Ph.D. He received his undergraduate and master’s degrees in reservoir engineering with a focus on improved oil recovery. Reza’s interest in environmental studies brought him closer to the applications of his prior experience in the field of groundwater remediation. Currently, he works on the modeling of groundwater remediation using electrical resistance heating with Dr. Magdalena Krol from York University. The model they are using, ET-MIP, is a combination of continuum-based models and discrete models. ET-MIP uses the continuum approach to simulate electrical heat generation, water flow, heat transfer, and mass transfer while using a discrete approach, macroscopic invasion percolation, to simulate gas transport. Given that this combined method is a new, and compared to conventional methods, a relatively untested method, the main focus of Reza’s research at York University is to first find the limitations and strengths of the combined approach used in ET-MIP and second to continually improve the model to best predict the reality.

“Kinetics of Naphthalene Biodegradation by the Thermophile JF8”

I'm a practical, hands-on, passionate engineer looking to improve how we do things. Right now, I am working on my PhD at the University of Toronto supervised by Dr. Brent Sleep. My research targets the interaction between biodegradation and thermal remediation, with the goal of generating experimental results to help enable the deployment of more effective, lower cost, and lower environmental impact remediation solutions for complex contaminated sites. After graduation, I hope to enter the remediation industry and translate the techniques I have studied into real-world applications.

Beyond remediation, I have a deep interest in sustainability. During my undergraduate degree in Civil Engineering at the University of Toronto I completed a double minor in Environmental Engineering and Sustainable Energy Systems. However, it became clear to me that our progress towards sustainable solutions is not just a matter of engineering prowess; it is determined by our ability as engineers to incorporate societal and economic realities into our work. As such, I expanded my scope to include extensive sociology-based courses, projects, and teaching work on the deep interconnection between technology, society, and the environment. This is a perspective I bring to all my engineering work.

In my spare time, I tinker with interesting technical projects. Currently, I am working on a custom-built smart home system to manage the off-grid family cottage. I'm also an aviation enthusiast; you will often find me watching videos on the topic or at the computer on a flight simulator.
