Frequently Asked Questions
Ques: Do I need a Computer Science background to apply for Oxford DPhil Computer Science, or can I apply from Mathematics or Physics?
Ans: You can apply from Mathematics, Physics, Engineering, or related fields if your proposed research is relevant to computer science. However, most admitted students have a Computer Science background or a strong upper second-class degree combined with a relevant Master's qualification. If you lack a CS background, your research proposal must clearly demonstrate how your prior expertise (e.g., mathematics, physics) applies to your proposed CS research area, and you should identify a supervisor whose work aligns with your background.
Ques: What is the realistic funding situation for international students applying to Oxford DPhil Computer Science, and are there specific scholarships for CS?
Ans: Approximately 15-20% of international DPhil students receive full funding from Oxford scholarships. Oxford-DeepMind Graduate Scholarships are specifically designed for Computer Science DPhil applicants and offer full fees + stipend, making them highly competitive. Most international students self-fund or combine partial Oxford funding with external sources (home country scholarships, employer sponsorship, personal savings). You should apply even without guaranteed funding if you can demonstrate financial capacity (via Financial Declaration) to cover at least the lower living costs estimate (£1,405/month = ₹1.76 Lakhs/month). Many students secure funding after receiving an offer.
Ques: Can I conduct my DPhil research outside Oxford, such as at a tech company or research lab, and what are the visa implications?
Ans: Yes, provision exists for students to undertake research in a 'well-founded laboratory' outside Oxford, which may require travel to and attendance at a site not located in Oxford. Existing collaborations with industry partners and research institutions are outlined on the course page. However, you must maintain full-time Student visa status and remain subject to Oxford's residence requirements, which typically mandate attendance in Oxford for core supervision and training. Visa sponsorship for full-time study remains valid as long as you are registered as a full-time DPhil student at Oxford, even if conducting research externally. Discuss specific arrangements with your supervisor and the Department before applying.
