Ritter studies cognitive modeling, cognitive architectures, human-computer interaction, and learning. He has taught cognitive modeling, skills to slow down the spread of COVID-19 and similar diseases, cognitive architectures, human-computer interaction, human factors, user interface design, cognitive psychology, artificial intelligence, and discrete math. He recently lead a team of ten medical doctors, nurses, learning scientists, nutritionists, psychologists, to create the first public health textbook to teach skills to obstruct pandemics (StOP), non-pharmacological interventions (NPIs), which are the first line of defense against disease. It is available as a free online tutor created using the Declarative to Procedure (D2P) tutoring system developed in his lab. He is working on a book for Oxford University Press on the design patterns to create, understand, and explain models of cognition and AI programs.
