Philip Guo (Phil Guo, Philip J. Guo, Philip Jia Guo, pgbovine)

My research spans human-computer interaction, programming tools, and online learning.

Philip Guo is an assistant professor of Cognitive Science and an affiliate assistant professor of Computer Science and Engineering at UC San Diego. His research spans human-computer interaction, programming tools, and online learning. He now focuses on building scalable systems that help people learn computer programming and data science. He is the creator of Python Tutor (, a widely-used code visualization and collaborative learning platform. So far, over five million people in over 180 countries have used it to visualize over 75 million pieces of Python, Java, JavaScript, C, C++, and Ruby code. Philip's research has won Best Paper and Honorable Mention awards at the CHI, UIST, ICSE, and ISSTA conferences, and an NSF CAREER award.

Philip received S.B. and M.Eng. degrees in Electrical Engineering and Computer Science from MIT and a Ph.D. in Computer Science from Stanford. His Ph.D. dissertation was one of the first to create programming tools for data scientists. Before becoming a professor, he built online learning tools as a software engineer at Google, a research scientist at edX, and a postdoc at MIT. Philip's website contains over 500 articles, videos, and podcast episodes and gets over 750,000 page views per year.
