Affiliations

I am an Associate Professor and William H. Hartwig Fellow in the The Chandra Family Department of Electrical and Computer Engineering at The University of Texas at Austin, where I direct the Human Signals lab. My research focuses on human-centered sensing and machine perception using wearable and ubiquitous technologies. My students and I explore how to build computational systems that make sense of people; intelligent systems that recognize and model people's behaviors and activities, health conditions, emotional state, surronding context, social interactions and more. I am affiliated with DICE, bioECE and SES. I am also a member of WNCG, iMAGiNE and a faculty affiliate of CAPS. I am an Editor of IMWUT and Steering Committee Chair for UbiComp.

  LLMs and Data Annotation
We have been exploring how LLMs might have an impact in activity recognition. Sloke has conducted studies centered on how they might change data annotation. For more details, check the paper, which will be presented at the CHASE 2024 conference. The paper is titled "Leveraging Large Language Models to Annotate Activities of Daily Living Captured with Egocentric Vision".
