Collins is a lecturer at the University of Environment and Sustainable Development in Ghana and 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. Collins is an emerging leader in the field of African air pollution exposure. 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. Anyone interested in collaborating with Collins on air pollution studies and capacity building projects in West Africa can reach him via and/ or on Twitter, LinkedIn, ORCID, Google Scholar, and ResearchGate.

Contributed to the development of a proposal as part of a consortium that won a grant for air quality management in West Africa (Air Quality Management Community of Practice in West Africa).

Developed a proposal that won a seed funding grant to test the robustness of low-cost sensors for understanding location-specific agricultural practices on local air quality in collaboration with the University of Ghana, OpenAQ, Clarity Movement and AfriqAir. The project will be executed with Gnana Council for Scientific and Industrial Research (CSIR).
