Inspired by the amazing diversity and utility of plants, my research uses phylogenomic, collections-based, and experimental field approaches to explore the evolution and genetic diversity of underutilized crops and their wild relatives, pollination, biogeography, and taxonomic revisionary work. I am also interested in applying findings to conservation of plant genomic resources and more sustainable agriculture.

Zerega Lab Group
The Zerega Lab aims to understand evolutionary processes in plants, especially as they apply to underutilized crops and their wild relatives. The research takes both a basic and applied approach with the goals of advancing crop improvement, sustainable agriculture, and food security, as well as informing the conservation of plant genetic resources. 

Graduate Program in Plant Biology and Conservation
This program is a collaboration between Northwestern University and the Chicago Botanic Garden. The graduate program offers thesis and non-thesis master’s degree and Ph.D. programs and aims to foster an academic and research environment that allows students to gain experience, skills, and knowledge to become scholars, leaders, and practitioners in plant biology and conservation.
