Hello! My name is Hangzhi Guo (郭杭之 | Birkhoff). I am a Ph.D. student in the College of Information Sciences and Technology (IST) at Penn State Uniersity advised by Dr. Amulya Yadav. Previously, I studied at a Wenzhou-Kean University majoring in Computer Science.

I desire to leverage advanced technologies to solve problems for marginalized groups. I am particularly fascinated about the idea of human-in-the-loop computing and dedicated to combine Machine Learning and Human-Computer Interaction to help under-served groups (including low-resource farmers, children with autism). Some of my past works were featured in multiple media, including, News Medical Life Sciences, and Penn State News.

My current focus is to build explainable AI systems for external stakeholders (e.g. doctors, judges, teachers). Feel free to drop me an email if you are interested in my work.
