Hi! I’m Mehak, a Computer Science PhD student at the University of California, Santa Barbara, advised by Prof. Yao Qin, and a member of the REAL AI Initiative.
My research centers on trustworthy and accessible AI, with a focus on real-world healthcare applications. My current projects include improving the confidence calibration of large language models, analysing their multilingual performance in post-training, and developing data- and AI- driven methods to improve automated insulin delivery systems for individuals with Type 1 diabetes.
Prior to this, I completed my MS in Computer Science at UC San Diego, working with Prof. Julian McAuley on data-efficient recommendation systems, and a B.Tech. in Computer Science & Engineering at IIT Delhi, where I worked with Prof. Aaditeshwar Seth on fairness in content recommendation. I also spent time as a software engineer in Samsung R&D’s On-Device AI team.
