I conduct research at the intersection of digital health, human-computer interaction, and data science, with a focus on how individuals with mild dementia and healthy older adults engage with text-based dementia online information. My work examines how older adults with and without cognitive challenges engage with digital health information, using webcam eye tracking and facial recognition to assess cognitive load, emotions, trust, and accessibility. I bring advanced expertise in mixed methods research, integrating quantitative modeling with qualitative insights to design inclusive, evidence-based digital health solutions that drive real-world impact.
