Research Interests:

As the director of the online psychology degree, I split my time between teaching and administrative duties for the Department of Psychology. At the undergraduate level I teach on average one course in the classroom and 1-2 courses online each semester. At the graduate level, I teach a course focused on best pracitces for teaching online and all graduate instructors new to teaching online are asked to take this course. I assist the department chair with administrative tasks related to the online psychology degree program, including the curriculum taught in each class, program assessment, and the development of new courses.
