Born in China and based in the UK for the past decade, I’ve been passionate about AI since deploying my first computer vision model (a fine-tuned ResNet). I'm a curious and driven learner, with experience building AI systems across domains like marketing and consumer apps. Lately, I’ve been exploring the frontiers of generative AI—tinkering with multi-agent systems, personalisation, and open-data tools to push what's possible.
I'm keen to explore how AI can drive social impact, particularly in justice systems and the nonprofit sector—areas where data is rich but often underused. I'm also deeply interested in generative AI for personalisation, especially in creating adaptive, user-aware experiences in digital products. I’m looking to connect with collaborators working on responsible AI, civic tech, or mission-driven applications of GenAI, and would love to exchange ideas or build together.
At Trainline, I’ve worked on a Travel Assistant—an LLM-powered chatbot using a multi-agent framework to help travellers post-booking. I’m now exploring reinforcement learning with LLMs to personalise experiences across app and web. Outside of work, I’m building models to simulate the criminal justice system, exploring system dynamics and policy impacts. I’m also developing an open data AI platform to help nonprofits better use their data for social good.
