Profile Summary

Dr Omar is Assistant Professor of Mechanical Engineering at the School of Engineering and Physical Sciences (EPS), Heriot-Watt University, Dubai Campus, since January 2023. His main area of expertise is in solar polygeneration systems and multi-phase flow modeling. He teaches courses in renewable energy, energy systems, thermodynamics, fluid mechanics, and heat transfer in the postgraduate and undergraduate levels.


Dr Omar earned his PhD in Mechanical Engineering from Khalifa University in 2020. Prior to that, he earned his BSc (2013) and MSc (2015) degrees in Mechanical Engineering from the American University of Sharjah. Prior to joining HWUD, he spent 2.5 years as a Post-Doctoral Fellow at Khalifa University. In addition to supervising and continuing to supervise a number of MSc and PhD students, he continues to be heavily involved in grant writing, course development, and research collaboration efforts.

Research interests

The main motive behind Dr Omar’s research is to develop smart, multi-functional particle-laden fluids for unconventional solar and thermal solutions, and their subsequent integration in polygeneration energy systems. He realizes this by drawing on the fields of thermal sciences, energy engineering, CFD, colloid science, and multiphase flow. The ultimate goal from his research is to provide economical and sustainable energy solutions and vectors that build upon the abundant solar resources in the MENA region.
