UIST 2023PaperToPlace is a novel workflow comprising an authoring pipeline, which allows the authors to rapidly transform and spatialize existing paper instructions into an MR experience, and a consumption pipeline, which computationally places each instruction step at an optimal location that is easy to read and does not occlude key interaction areas.
ASSETS 2023Assessing accessibility for wheelchair users can be challenging, due to lack of accessibility details needed for individual users. Embodied Exploration is a VR technique to deliver the experience of a physical visit while keeping the convenience of remote assessment. Embodied Exploration allows wheelchair users to explore high-fidelity digital replicas of physical environments with themselves embodied by avatars, leveraging the increasingly affordable VR headsets.
CHI 2023We present a prototype platform for tumor-contouring training that gives radiation-oncology residents overlap scores, visual cues for over- or under-contoured regions, and toxicity forecasts, enriching apprenticeship learning with timely, detailed feedback.
CHI 2023UnMapped merges a live 3-D “window” into the novice’s scene with a static 3-D replica of the expert’s own desk, letting mentors anchor instructions to familiar spatial landmarks. Compared with fully immersive views, this hybrid layout sped up remote guidance, reduced communication overhead, and eased expert workload.
IMWUT 2023Mites is a scalable hardware–software platform that deploys hundreds of privacy-aware, high-fidelity sensors across entire buildings—demonstrated with 314 nodes over five years in a five-story campus hall—to power diverse, machine-learning smart-building applications.

Implicit biases in healthcare harm communication, decision-making, and care quality for marginalized patients. Through co-design workshops with 32 BIPOC, LGBTQ+, and QTBIPOC individuals, we identified four patient-centered solutions: accountability measures, real-time correction, enablement tools, and provider resources. These insights advance patient-focused approaches to addressing bias in care.
Ph.D. Dissertation 2023Technology-mediated collaboration for physical tasks -- where a novice manipulates real objects in their space with the guidance of a remote expert -- helps extend expertise to remote and often resource-strapped environments. The spatial and immersive nature of emerging technologies like eXtended Reality (XR) promise to make this collaboration more natural and intuitive in ways that traditional screenbound collaborative systems can't.Ph.D. Dissertation, UC San Diego.

Ph.D. Dissertation 2023Augmented Reality (AR) displays show virtual information spatially in the physical world. For example, in the surgical domain, AR displays can overlay medical imaging on top of the patient to help surgeons distinguish healthy tissue from cancerous tissue.Ph.D. Dissertation, UC San Diego.
