He received his B.A. in International Studies, Geography, and Political Science from Macalester College, his M.A. in Geography from the University of Florida, and his Ph.D. in Geography from Rutgers University.

His Ph.D. research analyzed the impact of organic cotton production in Tanzania on sustainability, poverty and inequality. In 2012, he joined the Biovision Foundation based in Switzerland. As Programme Officer, he managed a diverse portfolio of pilot projects in East Africa, with a focus on disseminating ecological innovations. In his role as Scientific Advisor, he supported global advocacy efforts at the UN and the FAO. Since 2015, he managed the scale-out across sub-Saharan Africa of an ecological farming system - Push-Pull - developed by the International Centre for Insect Physiology and Ecology (icipe).

He has also worked as a consultant on farm-level sustainability assessments, a country-level review of biotechnology and its potential impacts, and global analyses of agricultural technologies for development.

He is currently leading research in collaboration with colleagues out of Rutgers University under a USAID subaward on the impact of COVID-19 on agricultural research and development (R&D) in Africa and Asia. His latest publication, "Integrated Health Interventions for Improved Livelihoods: A Case Study in Ethiopia,” looks at the impact of holistic development based on fieldwork in Ethiopia.
