Ph.D Program


Climate change is one of the existential challenges confronting humanity in the 21st century. ESS-PhD students join the global scientific community in the effort to define the causes and impacts of climate change and to develop effective solutions for a sustainable future. The ESS doctoral program provides graduate students with the perspective of the Earth as a coupled system and the technical know-how for a successful STEM career. Advanced course work in oceanography, atmospheric chemistry and dynamics, biogeochemistry, ecology, and human systems broadens students' perspectives and hands-on training in remote sensing, data analysis, modeling, and science communication refines critical research skills. Dedicated expert faculty and staff, state-of-the-art research instrumentation, and a commitment to team science provide an environment for a diverse student population to thrive, conduct groundbreaking research, and become the researchers, educators, and leaders of tomorrow.
