Opportunities

Generally, funded opportunities will be announced here as and when
they arise. However, some studentship opportunities are only
available after the student is identified so prospective students
are encouraged to get in touch as early as possible.
Please also do feel free to get in touch if you are a prospective
visiting researcher, industrial partner, or would like to
collaborate on a project.
