Overview

We are concerned with the responsible utilization of natural resources, issues of sustainability, as well as the mitigation of natural and manmade hazards and global change. We read Earth’s recent and ancient history in its rocks, fossils, landscapes, and its gravity. We probe and characterize the Earth system using satellites, in situ and laboratory measurements, physical theories, and numerical models. We conduct field work worldwide from Antarctica to the Arctic and from coral reefs to mountain peaks.

Our scientific activities and interests span an enormous range of temporal and spatial scales. We create and disseminate knowledge about our planet, develop new techniques to explore and understand it, and share this knowledge and our technical skills with our colleagues, our students, and society in the Earth Sciences programme at The Ohio State University.

Mission Statement

To assess human impact on the Earth system, and the implications of global change for the biosphere, society, and regional and global economies.
To educate the next generation of scientists, researchers, teachers, policy makers, entrepreneurs, and environmental professionals.
To promote a better informed populace within the state of Ohio, our nation, and worldwide.

General requirements

Contact potential advisors by phone, email, or in-person to ask about student opportunities in their group. Our directory contains a list of faculty members and their research expertise. Although contacting an advisor is optional, it is strongly recommended. The application will ask you to identify the faculty member you have been in contact with, and we will follow up with that person in the evaluation process.

Apply to the School of Earth Sciences using the online Graduate Admissions application. Applicants applying for fellowships and/or assistantships should check the appropriate boxes on the Graduate School application.

Be aware that requests to those writing letters of support do not contain the application deadline. Please inform your letter writers of the deadline.

We evaluate your application using a holistic rubric. Check out the evaluation categories carefully to understand how your application will be evaluated.
