My research focuses on the areas of Human-Computer Interaction (HCI), Health Informatics, and Computer-Supported Collaborative Work (CSCW). I study how people with chronic conditions live with and interact with technologies that support their care. Through qualitative and human centered design approaches, I examine how technologies such as medical devices, monitoring systems, and digital tools become integrated into everyday care practices. My work informs the design of technologies that better support long-term care and everyday health management.
Why research/HCI? I grew up in a generation shaped by technology. While rapid technological development has made life easier in many ways, it has also created new challenges for some people. My ultimate goal is to use scientific methods and technical skills to explore how technology can better serve people, creating work that makes a real impact on the world.

HCI research on goals and behavior change has significantly increased over the past decade. However, while emerging work has synthesized personal informatics goals, fewer efforts have focused on also integrating HCI research on behavior change to chart future research directions. We conducted a systematic review of 180 papers focused on goals and behavior change from over 10 years of SIGCHI journals and conference proceedings. We further analyzed 37 papers from the data set that included evaluations of interventions’ effectiveness in-the-wild. We also reported on the effectiveness of 76 of such technology-based interventions and the meta-analysis of 28 of these interventions. We find that most research has focused on goals in the health and wellbeing domains, centered on the individual, low intrinsic goals, and partial use of theoretical constructs in technology-based interventions. We highlight opportunities for supporting multiple-domain, social, high intrinsic, and qualitative goals in HCI research for behavior change, and for more effective technology-based interventions with stronger theoretical underpinning, supporting users’ awareness of deep motives for qualitative goals.

Living with Brain Data: Collaboration and Equity in Data-Intensive Brain Implants

Proceedings of the ACM on Human-Computer Interaction, 2025
This paper examines the lived experience of implanted medical devices through the case of brain implants for epilepsy. These data-driven devices record brain signals to detect and interrupt seizures, introducing new forms of technology-mediated care. Drawing on interviews with 17 patients and caregivers, we examine how data-intensive implants reshape medical interactions and everyday life. Participants reported shifts in doctor-patient collaboration, including the integration of a new expert—an engineer responsible for device-related concerns—into clinical visits. The preparatory and ongoing work of data transfer posed challenges for participants who were low-income, aging, traveling, or busy. Participants expressed a strong desire to access implant data to better understand and manage their condition. They were satisfied with the device unless their medications and/or seizures increased. We discuss emerging considerations for collaborative care and design justice introduced by medical implants that, unlike wearables, deliver treatment and cannot be easily set aside.
