Bandar AlOtaibi was born in Riyadh, Saudi Arabia. He received the B.S. degree in electrical engineering from Concordia University, Montreal, QC, Canada, in 2008. Under his undergraduate studies, he was with the NanoRobotics Laboratory, École Polytechnique, Université de Montréal, Montreal, where he designed circuits for generation of high-power and high-frequency electromagnetic fields for controlling nanoparticles to be used in hyperthermia-based treatments for weakening and elimination of malignant tumors and cancerous cells. He received his master degree in applied science from Concordia University in 2011, where he had been involved in the strain-engineering studies for selective tuning of the pinchoff voltage of AlGaN/GaN heterojunction field-effect transistors (HFETs) across the wafer and also microfabrication of AlGaN/GaN HFETs at McGill University’s Nanotools-microfabrication facility, Montreal. He had been also involved in characterization and mathematical modeling of the transport problem through AlGaN/GaN 2DEG channel at elevated temperatures in Micro-Devices and Fabrication Process Laboratory, Concordia University, for his master degree. In 2011, he joined McGill University, where he started detailed investigation on the photoelectrochemical hydrogen generation and CO2 reduction using metal-nitride nanowires. His research covers photoelectrode and photocatalysts design of the nanostructure materials grown by molecular beam epitaxy, device fabrication and characterization, photoelectrochemical experiments including H2 evolution and CO2 reduction measurements. His research also covers the fabrication and characterization of Si-based solar cells. He is interested in a broad area of physics and electrochemistry for solar-powered artificial photosynthesis applications including photoelectrochemical hydrogen generation and CO2 reduction for sustainable energy and green environment.
