His work focuses on aerosol dynamics, their societal impacts, and the development of effective control measures. He has investigated indoor and outdoor air quality, including airborne disease transmission and solutions for clean air in both developed and developing contexts.

Dr. Nasar leads an interdisciplinary research group focused on bioaerosol detection and analysis at Cranfield University. He is the institutional lead for the Biodetection Technologies Hub, which is funded by Research England. Additionally, he is a co-investigator on several projects, including INHABIT (MR/Z506680/1), DEFRAG (NE/W003031/1), and BioAirNet (NE/V002171/1).
