Caleb has a Ph.D. degree in Ecology and Environmental Protection in Applied Bioclimatology from Mendel University in the Czech Republic and an MPhil degree in Meteorology and Climate Science from the Kwame Nkrumah University of Science and Technology, Kumasi, Ghana. He has expertise in analyzing fluxes of matter and energy across different ecosystems using the eddy covariance method. His current research focuses on plant response and acclimation to climatic stress conditions across diverse forest ecosystems, especially in tropical African forests. He contributed to establishing an Eddy covariance station in a tropical Ghanaian moist semi-deciduous forest to monitor carbon and energy fluxes between the atmosphere and the forest, which is critical in better understanding the carbon sequestration capacity of African forests in mitigating climate change. He is also affiliated with the Earth Observation Research and Innovation Centre and worked with the Ghana Meteorological Agency as a Meteorologist (2013-2016) at the Numerical Weather Prediction Unit.
