Arpit Mathur
Ph.D. student at CMU
As a Ph.D. student at Carnegie Mellon University's Human-Computer Interaction Institute, I design and build human-centered AI systems for high-stakes domains, like healthcare. My work sits at the intersection of Human-AI Collaboration, Data Visualization, and Applied Machine Learning, with a strong emphasis on turning research ideas into working, usable tools.
I build end-to-end prototypes that help people reason with complex AI outputs, bridge expertise gaps between experts and non-experts, and support real decision-making. Across my projects, I work hands-on across the stack, from interaction design and front-end systems to model integration and evaluation with real users.
Before my Ph.D., I got my B.Des from the Indian Institute of Technology, Guwahati and earned an M.S. in HCI from the Georgia Institute of Technology. Through these experiences, I developed a strong foundation in applied HCI and systems thinking. I’ve also worked as a UX Designer at MathWorks, improving Model-Based Systems Engineering workflows for MATLAB and Simulink, which shaped how I think about designing tools for technical, expert users at scale.
Outside of academia, I enjoy video game design and development. You can find some of my Gamejam Submissions here. I love playing and watching football, and I'm an avid Arsenal fan.
