Zaheer Nasar is a Reader in Atmospheric Aerosols at Cranfield University and leads a multidisciplinary team for the Biodetection Technologies Hub. His research aims to enhance our understanding of airborne particles and their impact by advancing the physico-chemical and biological characterisation of aerosol emissions and leveraging advancements in sensing technologies and data analytics.

What inspired you to co-develop the concept behind the Hub?

Cranfield University has a long-standing research program focused on the detection and characterisation of bioaerosol emissions from diverse environments, creating a strong scientific foundation to support the development of appropriate policy and regulatory guidance. Our team at Cranfield possesses a range of expertise in aerosol science, engineering photonics, environmental chemistry, microbiology, sensors, and electro-optics. However, these capabilities have not yet been fully integrated. The establishment of the Hub presents an opportunity to build on and expand our capabilities by creating an Aerobiosense Research Group. This initiative will capitalise on synergies with the University of Hertfordshire’s Centre for Research in Biodetection Technologies, the University of Leeds and the University of Manchester, thereby advancing research and innovation in biodetection technologies.

Which collaborative opportunities excite you the most?

The opportunity to join forces with the Biodetection Technologies Hub enables us to engage in multi-disciplinary partnerships with a diverse range of stakeholders. This positions us at the forefront of emerging trends and technologies in the field of biosensors and their applications. It also allows us to build a talent pipeline for the next generation of researchers and innovators. By fostering partnerships with other institutions and organisations, our students and staff gain access to a broader network of expertise, mentorship, and resources.

What motivated you to explore bioaerosol detection as part of your research? 

My research interest is driven by the quest to uncover the physico-chemical and biological characteristics of aerosols, a vital step in grasping their fate and impacts. By transforming biodetection technologies to inform solutions for both indoor and outdoor air quality management, and by developing innovative rapid detection and response systems, we can realise a paradigm shift in our understanding of the role and impact of bioaerosols, with far-reaching implications across healthcare, atmosphere, agriculture, security, and industry worldwide.

What are you most proud of in your research career?

I take great pride in advancing Cranfield’s research in bioaerosol science and technology, providing thought leadership and fostering national and international partnerships, aiming to transform bioaerosol detection, enhancing our understanding of their role and impact on public and planetary health. Empowering early-career researchers, students and technical staff to achieve their career aspirations is also incredibly rewarding for me
