Hi, I'm Litao.

I am a Ph.D. candidate in Computer and Information Science at the University of Pennsylvania, advised by Andrew Head. I expect to graduate in May 2027. I am currently on the job market for research and engineering roles starting in 2027.

My research lies at the intersection of AI agents, developer tools, and AI evaluation. I build AI systems with new agent architectures and interaction techniques for understanding and inspecting AI-generated work, particularly in AI-assisted programming. I also develop task datasets and benchmarks to evaluate these systems through technical validation and studies of human understanding and use.

I have also worked on multi-agent systems and agent evaluation at Adobe Research, and multimodal AI systems at Microsoft Research. Previously, I received my M.E. in Computational Science and Engineering from Harvard University, where I worked with Elena Glassman on ExampleNet, which received a CHI Honorable Mention Award.
