Currently in Sunnyvale, CA

Hello! I’m Subbu, a researcher specializing in the intersection of Human-Computer Interaction (HCI) and Artificial Intelligence (AI). As a postdoctoral scientist, I design, develop, explore, evaluate, and apply advancements in intelligent user interface frameworks for AI applications. I work under the guidance of Alex Williams and Erran Li. My current work focuses on Conversational AI, Model Steerability, and Human-AI Agent interactions. I leverage my background in HCI to enhance data annotation processes for machine learning model development.

I earned my Ph.D. from Purdue University’s C Design Lab, where I specialized in designing, developing, and evaluating novel 3D interfaces and interaction techniques to progress Extended Reality (XR) applications. I am deeply passionate about the potential of AI to transform human interactions with technology and its implications for our future. My aim is to integrate my expertise in HCI with my current research in AI to drive innovation and enrich everyday life. My research has been published at premier venues for HCI research, including ACM CHI, CSCW, UIST, Ubicomp, DIS, and ISMAR.

Please reach out to me at subbu10123 [at] gmail.com if you find any of my work interesting. Thank you!
