Dr Nasar's research interest lies in physico-chemical and biological characterisation of aerosols, their spatio-temporal dynamics in different environments, societal impacts and developing control measures, with a specific focus on particulate matter (PM) and bioaerosols, across natural and indoor environments. He has extensively investigated aerosol and bioaerosols sources and dynamics under controlled as well as real-world built environments, the relationship between indoor/outdoor air quality and indoor air hygiene control measures in both the developed and developing world (EP/G029881/1, FP7-242497). He is leading Cranfield's work on the single-particle characterisation of biological materials in PM from different indoor and outdoor environments by using Light-Induced Fluorescence based sensor systems capable of performing a range of measurements on single particles in real-time ( NERC NE/M01163/1). He is Co-I on the Indoor/Outdoor Bioaerosols Interface and Relationships Network (BioAirNet/ NE/V002171/1) and also a member of BSI committee EH/2/5 - Emissions to internal environments as an expert on bioaerosols.
