Belal Abboushi joined the PNNL as a Post Doctorate Lighting Science Research Associate. Prior joining PNNL, Belal worked as an Assistant Professor at the School of Architecture at Marywood University. Belal earned a PhD in Architecture from the University of Oregon where he was involved in a number of research projects examining indoor environmental quality (IEQ), occupant’s comfort, and well-being in large-scale office and educational buildings. His doctoral dissertation utilized experiments and field studies to investigate occupant’s visual comfort and visual interest under different sunlight patterns in daylit offices. Belal was also involved in an interdisciplinary project exploring the effects of lighting and views on comfort and stress-recovery. He presented his research in various venues including the IES Annual Conference, LightFair 2019, and Greenbuild 2019.
