If you are a third year undergraduate student at the University of Oxford then you can apply to spend your fourth year under the supervision of Professor O'Hare. Information about the application process can be found here. In the O'Hare group the year is relatively structured with each Part II student being directly supervised by either a D.Phil or Postdoc. At the start of the year you will be given a project related in some way to that of your supervisor, enabling them to give you direct assistance as you learn the various practical/analytical techniques required. Over the course of the year you will have opportunities to practice various techniques such as presenting your work to the group at the weekly group meeting. By the end of the year you will be expected to produce a thesis of approximately 60 pages to submit to the examiners to complete your degree.
Potential Part II applicants usually come round to look at the group from late Michaelmas until the application deadline. If you are interested in learning more and applying to join the group then you should email Professor O'Hare.
