My name is Lucia (Lushi) Chen. I'm a postdoctoral research fellow at Stanford University, Center for Health Policy (CHP) / Center for Primary Care and Outcomes Research (PCOR). I obtained my Ph.D. in Informatics from the University of Edinburgh last month. My Ph.D. research concentrates on monitoring social media users' affective, cognitive, and behavioral changes, identifying the associations between digital signals and symptoms of mental disorders. I am interested in building human-centered health technologies, especially for low-income groups. I am also concerned about ethical issues and the potentially harmful effects of the technology developed in this line of work. I am passionate about identifying and developing good research practices and ethical standards.
