My research focuses on the causes and treatment of insomnia and related sleep deficiencies. Current interests include understanding sleep behaviors in the college student population, the development of cognitive interventions to treat insomnia, the development of smartphone applications to measure pre-sleep experiences, ethnic, cultural, and socioeconomic disparities related to sleep disorders, and the intersection between sleep behaviors and alcohol and marijuana usage. I currently teach courses related to clinical and health psychology (Introduction to Psychotherapy, Introduction to Clinical Psychology, Abnormal Psychology, and Laboratory in Health Psychology).
