Penn State’s PhD in Agricultural Sciences prepares researchers to lead sustainable innovations in food production, environmental conservation, and agricultural economics. Students explore agroecology, plant breeding, soil science, entomology, animal nutrition, and rural development, working across labs, farms, and international field sites. The program fosters collaborative, cross-disciplinary research targeting climate change, food security, and agricultural resilience.
