Roles

  • AI lead (R&D) From June 2026, alongside the PhD: the company's AI platform and model gateway, its AI transformation, and AI for global messaging. Ongoing
  • Graduate Teacher · Demonstrator Weeks into the PhD: a Demonstrator contract in SEMT and a Graduate Teacher contract in the School of Mathematics. Completed
  • PhD researcher From 3 Nov 2025 in SEMT: random-walk first-passage times — why a single target can produce two arrival peaks. Ongoing
  • Researcher (Internship) 4–16 August 2025, Silicon Valley: finding the most reliable way to turn product manuals into clean Markdown for an AI knowledge base. Completed
  • Platform developer An AI career-matching platform for a university's Beijing centre: upload a CV, confirm a profile, see matches explained on six dimensions. Live
  • Research intern Summer 2024, through the Sichuan–Hong Kong internship programme: market research, large-scale data cleaning and a first real office. Completed

All chapters

  1. 01 First Passage Why can a single target produce two arrival peaks?
  2. 02 Skipping the IME? Can you skip the input method and just type pinyin to an AI agent?
  3. 03 The Engine Room Since June 2026, AI lead (R&D) at Yuexin International: the internal AI gateway, an enterprise platform for governed model access, the staff AI assistant, and the connectors that let agents work inside the company's own tools.
  4. 04 On Stage How a messaging company learns to present itself as an AI company: a first overseas brand push, a logo argued from four sketches into one mark, print kits for two trade floors, and a 93-minute primer that taught the LLM industry through SMS.
  5. 05 Teaching A Graduate Teacher from the first month of the PhD: problem classes, labs, marking and tutorials — now thirteen teaching roles across eleven units in three schools, run with the same AI-native habits as the research.
  6. 06 Representing Speaking for other PhD students, and for the university: two years as Engineering Mathematics PGR rep, a scholarship reading panel, open days, a science festival — and seven minutes of stand-up about doing a maths PhD.
  7. 07 Map in. Traps out. First-passage maths turned into a product: BioPath takes a site map and a budget and returns where to put the traps — with the proof attached.
  8. 08 Signal A camera roll kept since 2023, a WeChat studio launched in August 2026, LinkedIn as a public notebook, a home-built bilingual subtitle pipeline — and the long making-of of the site you are reading.
  9. 09 Westward Summer 2025: a university programme in Silicon Valley and a two-week research internship at LiveX AI, where the question was how to turn messy manuals into Markdown an AI can actually use.
  10. 10 Workshop Things built in the gaps: a maths guide for the next cohort, a travel-story studio born at a hackathon, a cursor that jumps between screens, bridges that let AI agents hand work to each other — most of them made so that someone else could move faster.
  11. 11 Roots Tianjin, Hong Kong, Chengdu, Geneva, Bristol: a maths degree with an oar in hand, an exchange year that turned the maths computational, a first internship, and the 3+1 route — the first shortcut, which skipped a year.
  12. 12 Now & Next As at the build date: a poster to present in Edinburgh, a paper submitted to Physical Review E and another in preparation, a desktop agent in development, a new teaching year and a second year as PGR rep.
  13. ∂ The absorbing boundary
