Cho holds a PhD in hyperspectral remote sensing from the International Institute for Geoinformation Science and Earth Observation, Enschede, and the University of Wageningen, Netherlands. His key research interest involves developing earth observation  tools, applications or products that support planning and decision-making for Precision agriculture, biodiversity conservation in rural and protected landscapes, particularly in Africa; hyperspectral imagery, and active remote sensing (lidar and radar) for assessing and monitoring floral diversity, vegetation condition (e.g. nutrient status) and productivity, and land-cover change processes at different spatial scales; modelling the effects of habitat (e.g. forest) fragmentation and vegetation change on ecosystem functioning and rural livelihoods. Cho is also a professor with the plant and soil science department at the University of Pretoria, an NRF rated scientist, the convener of the technical committee on algorithm development and application for the African Association of Remote Sensing of the Environment, president of the African chapter of the International Association of Landscape Ecology and an associate editor for the International Journal of Applied Earth Observation and Geoinformation.
