Hello! I'm Litao Yan, currently pursuing my Ph.D. at UPenn under the guidance of Prof. Andrew Head. My research is deeply rooted in human-AI interaction, focusing on how humans and AI can collaboratively enhance each other's capabilities. I'm particularly passionate about developing programming assistants with the power of large language models (LLMs) that can seamlessly integrate with developers' workflows, making the coding process more intuitive and efficient.
