Introduction
Ilyas Cherchar (born 15 March 1978) is a multidisciplinary scholar and engineer recognized for his contributions to sustainable energy systems, computational modeling, and public policy advocacy. His work spans academia, industry, and governmental advisory roles, influencing energy transition strategies in several countries. Cherchar holds dual appointments as a professor of electrical engineering at the University of Oslo and as a senior fellow at the International Renewable Energy Agency (IRENA).
Early Life and Education
Family Background
Born in Copenhagen, Denmark, Ilyas Cherchar was raised in a multicultural household. His father, Ahmed Cherchar, emigrated from Morocco as a textile engineer, while his mother, Lina Cherchar (née Nielsen), worked as a civil engineer specializing in coastal infrastructure. The family emphasized scientific inquiry and community service; Ilyas participated in volunteer environmental projects organized by the local municipality during his childhood.
Primary and Secondary Education
Cherchar attended the Øresund International School, where he excelled in mathematics and physics. During high school, he was awarded the Danish National Science Competition prize for his project on photovoltaic cell efficiency. He also engaged in the International Baccalaureate program, achieving a score of 42 points, with particular strength in the sciences.
Higher Education
In 1996, Cherchar entered the Technical University of Denmark (DTU), enrolling in the Bachelor of Science program in Electrical Engineering. He completed his undergraduate degree in 2000, graduating with distinction. His senior thesis, titled “Dynamic Modeling of Wind Turbine Gearboxes,” received the DTU Faculty Award for Outstanding Research.
Following his bachelor's degree, Cherchar pursued a Master of Science in Renewable Energy Systems at the University of Strathclyde in Glasgow, United Kingdom. The master's program, completed in 2002, combined coursework in thermodynamics, control systems, and renewable resource assessment. His master's thesis examined the integration of solar PV arrays into district heating networks, earning him the Strathclyde Graduate Research Prize.
Cherchar then advanced to doctoral studies at the Massachusetts Institute of Technology (MIT) in the United States. He enrolled in the Department of Electrical Engineering and Computer Science, focusing on computational fluid dynamics (CFD) for offshore wind farms. His dissertation, completed in 2007, introduced a novel CFD framework for predicting turbine wake interactions in turbulent atmospheric boundary layers. The work was published in several high-impact journals and cited extensively in subsequent offshore wind research.
Career
Early Professional Years
Immediately after his Ph.D., Cherchar accepted a postdoctoral fellowship at the National Renewable Energy Laboratory (NREL) in Colorado, USA. From 2007 to 2010, he collaborated with the NREL Wind Technology Office, conducting field experiments to validate CFD models of wind farm performance. His work contributed to the development of best‑practice guidelines for wind farm layout optimization.
Academic Contributions
In 2010, Cherchar joined the faculty at the University of Oslo (UiO), initially as an associate professor in the Department of Energy Engineering. He advanced to full professor in 2015 after publishing a series of landmark studies on hybrid renewable energy systems and smart grid integration. His research group, the Sustainable Energy Systems Laboratory (SESL), focuses on multidisciplinary approaches combining electrical engineering, economics, and environmental science.
As part of his academic responsibilities, Cherchar has supervised over 30 Ph.D. candidates and 70 master’s students. Several of his former students have gone on to hold positions in academia, industry, and governmental agencies, underscoring his influence on the next generation of energy researchers.
Industry Engagement
Cherchar maintains active collaboration with the renewable energy sector. Between 2014 and 2018, he served as an independent technical consultant for Ørsted A/S, advising on the design and operation of offshore wind farms in the North Sea. He also consulted for the European Commission’s Horizon 2020 program, providing expertise on the economic viability of distributed generation projects.
In 2019, Cherchar co‑founded the startup GreenWave Technologies, which develops advanced control algorithms for marine energy harvesters. The company secured Series A funding in 2020 and entered into a partnership with the Norwegian Ministry of Trade to pilot a marine energy demonstration project in the Arctic Ocean.
