If you are interested in working with me for a PhD and have a credible source of funding, please email me (firstname.lastname@example.org) to discuss possibilities. Graduate students in Oxford Theoretical Physics are typically funded either by STFC studentships, scholarships from Oxford University or from their home country, and sometimes by research grants.
Please also read the guidance for PhD applicants on the webpage of the Oxford particle theory group.
I do not offer work experience placements to secondary school students or have suitable projects available. The Oxford Physics Department does offer a work experience scheme, please contact Sian Tedaldi for more details.
