I'm a researcher in Human-Computer Interaction (HCI) and Usable Privacy & Security. My research explores how we can design interactive technologies that support privacy and user agency in data-rich environments.

I conduct user-centered studies to understand the security and privacy needs of people engaging with technologies like mobile sensing, wearable devices, smart homes, and AI systems. Based on these insights, I design and build interactive systems that help users make sense of their data, manage what’s shared, and stay in control.

Grounded in human-centered design, my work integrates usable privacy, ubiquitous computing, AI ethics, and data interaction to develop systems that promote responsible, user-driven engagement with technology.
