Full Profile
From an early age, Hams Hefny was driven by a deep passion for the automotive industry and a desire to contribute to a more sustainable future. Her curiosity about how things work—and how they could work better—led her to engineering, where she discovered the tools to solve real-world challenges. Her commitment to clean energy and electrified transportation has guided both her academic and professional journey, placing her at the intersection of innovation and environmental responsibility.
Hams envisions a future where electrified transportation is not only widely adopted, but also optimized for performance, safety, and efficiency. Her goal is to contribute to this transition by developing scalable, cost-effective thermal solutions for electric motors, batteries, and power electronics. She is especially focused on advancing the science of cooling technologies, believing that intelligent thermal systems are essential to the success of next-generation electric vehicles.
As a thermal design and research engineer, Hams specializes in thermal management solutions for electric motors, batteries, and power electronics. Her expertise includes air- and liquid-cooled thermal systems, electromagnetic modeling, and computational fluid dynamics (CFD), which she applies to improve the efficiency and reliability of cutting-edge technologies. At McMaster University, she worked on several high-impact projects in collaboration with Stellantis, addressing complex multiphase cooling challenges in electric motors. In addition to her research, she served as a teaching and research assistant, mentoring undergraduate students in thermodynamics, heat transfer, and fluid mechanics—bridging academic knowledge with practical engineering applications.
Her technical strengths include electric motor thermal management, the development of real-time and lumped parameter thermal network (LPTN) models, and the optimization of water- and oil-cooled permanent magnet synchronous machines (PMSMs) using advanced CFD simulations. She has also designed and analyzed thermal systems for EV battery packs, collaborating with the U.S. Department of Energy and Argonne National Laboratory to enhance both thermal and hydraulic performance. In the area of power electronics, she has engineered heat sinks, cold plates, and heat pipes. Hams also leverages Python scripting in PyMotorCAD to automate and streamline thermal modeling workflows, ensuring both precision and efficiency in simulation processes.
