I have a background in Chemical-Mechanical Engineering, specializing in integrated hydrogen energy systems. With my Ph.D. in Mechanical Engineering from Ontario Tech University and an MSc in Chemical Engineering from the Illinois Institute of Technology, my journey has been marked by a commitment to advancing sustainable energy solutions.

My research transcends traditional boundaries, focusing on the circularity and sustainability of energy systems, emphasizing the pivotal role hydrogen can play in our sustainable future. Utilizing the principles of the second law of thermodynamics, I have been dedicated to uncovering optimized decarbonization pathways tailored for various end-user applications. This unique approach has contributed to the theoretical understanding of energy systems and practical, real-world applications that pave the way for a sustainable, low-carbon future.

My work has been recognized with several prestigious awards, including the Governor-General of Canada's Gold Medal for Academic Excellence and the Outstanding Young Scientist Award from the Turkish Academy of Sciences. I have continued pushing the boundaries of hydrogen energy knowledge, receiving accolades like the Zong Qiang Mao Award from the International Journal of Hydrogen Energy.

In my current role, I am not just imparting knowledge but actively shaping the next generation of energy solutions. Through my research and teaching, I aim to inspire a new wave of innovation in sustainable energy, contributing to a world where energy efficiency and environmental responsibility go hand in hand.
