02 / Research
Understanding what
changes, and why.
During my July–September 2026 internship at Foresight Fund, I researched China’s restaurant sector and AI economics, and built tools for financial research. These questions continue to inform my work.
Company research
Yum China, restaurant-sector analysis, and valuation modelling.
AI & the economy
AI investment returns, consumer monetisation, and white-collar automation.
Research tools
Workflows that turn company disclosures into financial ledgers and Excel workpapers.
03 / A little context
Hi, I’m Pengyu.
You can call me Peter.
I’m studying Mathematics with Data Science at the London School of Economics and Political Science. My interests sit between mathematics, software, and investment research.
I enjoy working through the details: how a company earns its returns, how an agent handles a long task, or why a particular move works on the Go board.
