Research Bio

Dinesh Ayyappan

After a career teaching high school physics and computer science in three countries, I became a researcher interested in AI, fairness, and education.

I was trained as an engineer at Carnegie Mellon and then as a teacher in the Boston Teacher Residency. After teaching for 10 years in public, private, and international day and boarding schools, I completed a M.S. in Computer Science from Georgia Tech. There, I worked with Ashok Goel and the Design Intelligence Lab and completed a Master's Project with David Joyner. Both collaborations led to published research on using computational methods to improve learning in open-ended contexts

In 2025, I began a Ph.D. in the Social and Responsible Computing research group advised by Carlos Castillo at Pompeu Fabra University, where I am studying fairness and safety in large language models.

Personal

I try not to move too fast in the world, and I think it's a perfectly fine use of time to just look out the window on a bus ride instead of reading, texting, or listening to a podcast.

As a teacher and parent, it's important to me that I'm always learning and doing things that remind me what it's like to be a beginner. This partially explains why I work on languages that I'll probably never speak fluently (like Hindi, Chinese, and Catalan), and why I was happy to borrow my friend's longboard even though I've never quite gotten the hang of wheels or skates.
