Miscellaneous research:

• Pairings in cryptography, new and old (MathCrypt 2025)
• Local-to-global in thin orbits (Rational Points 2025)
• Reciprocity obstructions in Apollonian circle packings and continued fractions (slides, video)
• AMMCS (slides; isogeny-based cryptography and oriented isogeny graphs)
• Mathcrypt (slides; a factoring algorithm)
• AMS Invited Address:  An Illustration in Number Theory
• Farey Colloquium – starting with Farey fractions, heading to the complex plane
• Some Arithmetic Aspects of Ring-LWE
• Quantum Computing and the Future of Cryptography – this was given at the Harvard Open Neighbourhood Seminar (for undergraduates), and explain’s Shor’s algorithm and isogeny-based cryptography
• YouTube playlist of videos of me giving lectures (in no particular order and probably missing some)
• YouTube playlist of some of my collaborators (mostly about joint work)

General interest:

• It was a great honour to be featured as part of a webinar series with The National Academies, along with Jordan Ellenberg and moderated by Terry Tao.  You can watch here.
• Public Lecture: The illustrated field diary of a mathematical naturalist [ odp (libreoffice Impress; original version) : pptx (power point conversion; haven’t tried it; YMMV) : pdf (exported; colours ruined, videos cropped; YMMV) ] from PRIMA 2023.
• My occasional YouTube Channel ProofOfConcept
• My dad’s TedX Talk (about creativity)
