The Earth sciences are the focus of scientific understanding about this and other planets, embracing a large range of fundamental topics including the evolution of life, how climate has changed in the past and will change in the future, the nature of planetary surfaces and interiors and the processes underlying natural hazards like earthquakes and volcanoes. The DPhil is an advanced degree by research that will take between three to four years to complete. You will have at least two (and sometimes more) supervisors, who are experts in their field, and who provide the project research framework, guidance and mentoring throughout the program. Examination of the DPhil is in three stages. After the first year and between years two and three a formal report, presentation and interview are required to confirm your status as a DPhil candidate. At the end of the degree a written thesis is submitted and this is examined viva voce by an external expert in the field and moderated by an internal member of faculty. Many graduates choose to stay in academia. Others go on to environmental work or work in industry. The Department of Earth Sciences has an active and vibrant alumni network. With an annual newsletter, alumni dinners, networking and other events throughout the year, there are many different opportunities to keep in contact with the department.
