Sohaib is a PhD researcher at the University of Hertfordshire, a leading aerosol science and interdisciplinary research institution working towards developing novel methods for collecting and analysing airborne human DNA. After completing a master’s degree at Hertfordshire in the same research group, he became fascinated by the challenge of detecting biological traces in the air. 

What are you working on within the Hub? 

My research focuses on the future of airborne DNA collection. While existing forensic and biological sampling methods rely on surfaces and bodily fluids, I am exploring how human genetic material disperses in the air and how we can efficiently collect it. The goal is to design and optimise innovative aerosol collection devices that can capture and preserve DNA signatures from the environment. 

Currently, I am developing and refining experimental setups to assess the best methodologies for air DNA sampling. By combining theoretical modelling with hands-on experimentation, I aim to create a reliable and efficient system that can one day be used in forensic science, biosecurity, and environmental monitoring. 

What is the impact of your research so far? 

While I have yet to collect human DNA from the air, my research sets the foundation for future breakthroughs. My work involves evaluating different aerosol sampling techniques and optimising the conditions for successful air DNA capture. Developing these methods requires an interdisciplinary approach—bridging aerosol physics, molecular biology, and engineering to refine our understanding of airborne genetic material. 

What has been the highlight of your research career to date? 

One of the most rewarding moments of my research journey has been securing a PhD position within the same lab where I worked as a master’s student. The opportunity to continue my work in such a familiar and intellectually stimulating environment has been reassuring and inspiring. Thanks to Hertfordshire's genuinely impressive and supportive team, the transition from student to researcher has been seamless. 

Being surrounded by knowledgeable and helpful colleagues has made my PhD journey productive and enjoyable. So far, the biggest highlight of my research career has been realising how difficult it is to collect air DNA. While that might sound discouraging, it's exciting—every challenge presents an opportunity to innovate
