Daniel Naylor

Daniel Naylor is a mathematician from Oxford, United Kingdom. As a school student at Matthew Arnold School, Oxford, he was selected for the UK team at the 62nd International Mathematical Olympiad (IMO 2021), scoring 9 points and earning an Honourable Mention as part of the team that finished equal 9th of 107 countries. He went on to study mathematics at the University of Cambridge, where he is now a postgraduate research student in the Department of Pure Mathematics and Mathematical Statistics (DPMMS), working in combinatorics. He publishes detailed Cambridge maths lecture notes and flashcards at danielnaylor.uk, which are widely cited by other students.

• Represented the UK at IMO 2021 (held remotely from St Petersburg) and earned an Honourable Mention with 9 points (P1=7, P2=1, P3=1), placing 332nd of 619 contestants; the UK team scored 131/252, equal 9th of 107 nations.
• Was selected for the UK IMO 2021 team while at Matthew Arnold School, Oxford, alongside Mohit Hulse, Isaac King, Samuel Liew, Yuka Machino and Jenni Voon; the team leader was Dominic Yeo (Oxford) and deputy Sam Bealing (Cambridge).Jun 6, 2021
• Now a postgraduate (research) student in Cambridge's Department of Pure Mathematics and Mathematical Statistics (DPMMS), suggesting a move from undergraduate maths into combinatorial research.
• Attended the 30th Postgraduate Combinatorial Conference (PCC 2026) at the University of Warwick, an event for current research students in combinatorics, confirming an active research-student status in combinatorics.Apr 2026
• Won a Silver medal representing the University of Cambridge in Round Two of the 8th International Mathematics Competition (ICMC) 2024-25, scoring 36/40 (90.5%) across the papers.2025
• Runs danielnaylor.uk, publishing full Cambridge maths lecture notes (PDF + HTML) and flashcard decks for IA/IB/II courses; his notes are cited in university seminar reading lists, e.g. a Hebrew University Kazhdan seminar referencing his EMC notes.
• Served as a marker for the British Mathematical Olympiad Round 1 2023, listed in the UKMT markers' report, indicating he stays involved with UK olympiad training after competing.Dec 2023
• Also competed for the UK at the Romanian Master of Mathematics 2021, named to the squad announced April 2021 while at Matthew Arnold School, Oxford.Apr 20, 2021
• His personal site lists contact email [contact omitted], the most direct public contact route.
• DO NOT CONFUSE with unrelated namesakes: a Daniel Naylor (UCSB/UCI statistics) teaches at Euler Circle, and a 'Daniel Naylor' is a Senior Consultant at Opencast; neither is the UK IMO 2021 contestant.
• Was among the participants/contributors associated with Cambridge maths student note-sharing hubs (at2027 hub lists him for the 2023-24 Number Theory notes).
