Zhiyuan Wang
I am a third-year PhD candidate in Systems and Information Engineering at the University of Virginia (UVA), working with Prof. Laura E. Barnes in the Sensing Systems for Health Lab and the Link Lab. I obtained my Bachelor's degree in Computer Science from Xiamen University in 2021. My research lies at the intersection of mobile sensing, AI, and health. Working with interdisciplinary collaborators and stakeholders from medicine, nursing, psychology, and bioethics, I develop ubiquitous sensing and intervention systems to enhance human well-being. I received awards including 2024 CPS Rising Star, Departmental, and UVA Engineering Teaching Fellowships.
Keywords: Digital Health, Ubiquitous and Mobile Computing, Human-Cenetered Interactive Technology
My research utilizes mobile devices to sense, analyze, and understand health-related contexts and inform Just-In-Time Adaptive Interventions (JITAIs) to improve human outcomes in context.
