  • Postdoctoral Research Associate, College of Engineering, University of Georgia


Collins is a postdoctoral research associate at the College of Engineering, University of Georgia within the Engineering Environmental Equity (E3) Lab of Christina H. Fuller. Collins is an emerging leader in the field of air pollution exposure. Prior to joining UGA, he was a lecturer at the University of Environment and Sustainable Development in Ghana. He is also the Founder and Director of Operations at Clean Air One Atmosphere - a nonprofit using air sensors to revolutionize air quality monitoring and data communication in Ghana and Wider Africa. He received his PhD from Cranfield University in the UK and then returned to Ghana to apply his expertise close to home. He has secured a number of international collaborations with Global North experts. In particular, he is a member of CAMS-Net (a “network of networks” for air quality), National Science Foundation Funded group led by Prof Daniel M. Westervelt of Columbia University, USA. Through this project, Collins was one of a few network members to receive seed funds for small air quality research projects. His project aims to understand PM2.5 exposure using well-calibrated low-cost sensors in agricultural settings in Ghana. He is also involved in another CAMS-Net project involving PM2.5 exposure in schools in the Ashanti region of Ghana. Generally, Collins collaborated with Global North experts on ground-breaking air pollution research and capacity building in West Africa towards air pollution management and control. In addition to his scientific research accomplishments, he is also passionate about environmental activism in his home country and is leading the fight for cleaner air for all Ghanaians. His work is featured in globally recognized American Geophysical Union Eos, PurpleAir blog and Climate Break.
