His research focuses on understanding the genetic mechanisms of adaptation and how those adaptations contribute to the formation of new species. The Plant Resilience Institute provides an excellent opportunity for collaborative research to identify the genetic and physiological mechanisms of how plants tolerate abiotic and biotic stresses. David is particularly interested in understanding the mechanisms underlying genetic variation in heat tolerance in the common bean, Phaseolus vulgaris. Heat is one of the most limiting factors for this important source of protein in Latin America and Africa.”
