Dr Samuel Tetteh Partey, a Ghanaian national, joined CCAFS West Africa (ICRISAT-Mali) as Science Officer in July 2015. Dr Partey is an expert in soil-plant relations and agroforestry. He holds a PhD in Environmental Biology (specialisation in soil science) from the University of Manchester (UK) and a PhD in Agroforestry from the Kwame Nkrumah University of Science and Technology (KNUST), Ghana.

Prior to joining ICRISAT, Dr Partey was a lecturer at KNUST, as a Senior Researcher and Project Manager for bamboo-based agroforestry project led by the International Network for Bamboo and Rattan (INBAR). Dr Partey has been involved in several collaborative projects: In 2014, he was the Agroforester for Ghana on a Royal Society funded project on the environmental importance of forest islands in the Guinea Savannah zone of Ghana led by Imperial College, London; In 2013, he served as a Data Analyst for N2-Africa (Ghana Chapter), and a CIDA-funded Agroforestry Practices for Enhanced Rural Livelihood Project led by the University of Guelph, Canada.

In 2012, Dr Partey was a GRiSS Visiting Scholar at the Africa Rice Centre in Benin where he was involved in agronomic trials on biochar use in rice cropping systems. He is well versed in the use of decision support systems and tools for agro-technological development; statistics and state-of-the-art novel techniques in soil microbiology and biochemistry. Apart from synthesizing knowledge and contributing to strategic research of interest to CCAFS, he will also be handling administrative tasks for the CCAFS regional programme for West Africa, especially with regards to the development and advancement of partnerships.
