Biographical Sketch
Kathryn received her Bachelor of Science degree in Psychology from the College of Charleston in 2012. She worked as a post-baccalaureate research assistant at the Medical University of South Carolina from 2012 to 2015 and subsequently enrolled in the Clinical Psychology doctoral program at the University of Memphis. Kathryn worked in the HABIT lab as a research assistant and clinician on two of Dr. Murphy's brief intervention trials to reduce heavy alcohol and cannabis use in college student young adults. Her research interests include utilizing behavioral economic principles to better understand the relation between negative affect and substance misuse in young adults, as well as the development and utilization of technology, in order to improve brief interventions for this population. As such, Kathryn's master's thesis focused on elucidating behavioral economic mechanisms that may play a role in the relation between negative affect and alcohol-related problems in young adults. Kathryn is currently in her 5th year and working on her NIH (F31) funded dissertation project evaluating the feasibility and preliminary efficacy of a text-message delivered brief intervention for reducing alcohol misuse in young adults.
