Research Interests & Projects
My research interests have focused on creating, implementing and evaluating novel interventions to deliver chronic disease screening, where the infrastructure to carry out conventional laboratory tests is often unavailable in low-resource settings. In particular, I am interested in various aspects of human computer interactions: exploring user interfaces for low-cost devices, adapting content and applications to local languages and education levels, and understanding social relationships and information flows in disadvantaged societies.
Currently, I am developing and evaluating a lung cancer screening decision tool, shouldiscreen.com, that helps inform interested individuals in the potential harms/benefits of low-dose CT screening. I am also involved in developing a screening tool for a range of chronic diseases for use in Guatemala.
