Rita Orji

Rita is a ‎Postdoctoral Fellow at McGill University, Canada and a Visiting Senior Lecturer of Computer Science at the Nnamdi Azikiwe University. Her research examines how interactive technologies can be designed to motivate desirable behavior change. She is particularly passionate about studying how Persuasive Technologies and Behavior Change Support Systems can be designed to help people move towards improved health and wellness. Rita is interested in wide area of health behaviors, including sexual risk behaviors, healthy eating, physical activities, smoking cessation, and other health risk behaviors. For the past five years, she has been researching on various ways of tailoring persuasive technological interventions to increase their relevance and effectiveness using the user-centered design approach.
