Nancy W. Mungai is a professor of soil science with research interests in biological nitrogen fixation in grain legumes, biological agricultural inputs, and relevance of soil-based approaches for adaptation & mitigation to climate change. She has successfully coordinated twelve research projects and several student internship programs. Nancy is currently involved in a project titled "Transforming African Agricultural Universities to meaningfully to contribute to Africa’s growth and development (TAGDev, Phase 2), a partnership of Egerton university with eleven other universities including Gulu University funded by Mastercard Foundation through RUFORUM. The project is in second phase after successful implementation of TAGDev 1 which supported over 188 undergraduate and postgraduate students to pursue various agricultural related disciplines including agronomy, horticulture, agribusiness and food nutrition and security. TAGDev 1 piloted an innovative model for agricultural training that facilitates agricultural students to work closely with rural communities to foster transformation of the agrifood system at several levels starting with the individual student/staff level, institutional level and at the national level. Community action research approaches have been at the center of TAGDev project implementation.

Nancy has supervised 20 graduate students and has published over 90 publications in internationally refereed and peer-reviewed journals, conference proceedings and technical reports.

Administratively, Nancy is the Ag. Director in charge of Research and Extension at Egerton University since March 2020. Previously she served as the Director in charge of undergraduate studies and field attachment programs for 9 years.
