Current Students

Lauren Breithaupt

Lauren Breithaupt

Lauren Breithaupt is a doctoral student in George Mason University’s Clinical Psychology program, working with Dr. Sarah Fischer. Lauren received her Bachelor of Science in Psychology from Baker University in Baldwin City, KS and Master of Arts in Psychology from George Mason University. Lauren’s research broadly focuses on understanding eating disorders from a neurobiological perspective and the effect of certain interventions, both treatment and prevention, on behavior and associated brain function in eating disorders. Current research projects aim to better understand the broad array of factors that create and maintain the biological and psychological setting that support eating disorder cognitions and behaviors. Her research is funded through the National Science Foundation, American Psychological Association, REbeL Peer Education and the Zeta Tau Alpha Foundation.

Catherine Byrne

Catherine Byrne

Catherine Byrne is a third year doctoral student in George Mason University’s Clinical Psychology program and works with Dr. Sarah Fischer. Catherine received her Bachelor of Arts in Psychology from Marquette University in Milwaukee, WI and Master of Arts in Psychology from George Mason University. Catherine’s long-term research interests include examining factors that mediate treatment outcomes of youth with eating disorders and the development and enhancement of interventions for youth with eating disorders. Current research

projects include (1) examining the link between social media and eating disorder risk, and (2) understanding the behavioral mechanisms of cognitive dissonance by challenging the societal ideals of physical appearance

Joseph Wonderlich

Joseph Wonderlich

Joseph Wonderlich, a third year doctoral student in Clinical Psychology at George Mason University, works with Dr. Sarah Fischer in the Impulse Lab. Joe received his Bachelor of Arts in Psychology and Peace Studies from St. John’s University in Collegeville, MN. Joe’s primary research interests include: 1) The interface of impulsivity and emotional dysregulation across a broad range of psychopathology, 2) Neurobiological pathways associated with impulsive behavior, 3) innovative assessment technologies for measuring psychopathology. Currently, Joe is working on a several studies in the Impulse Lab. These studies aim to examine the relationship between stress and craving utilizing fMRI and Ecological Momentary Assessment, as well as integrating EEG and Ecological Momentary Assessment to asses the impact of neural responses as a result of changes in affect and their relation to impulsive behavior in the real-world environment. Joseph’s research is funded through the National Science Foundation.

Naomi Pak

Naomi Pak

Naomi Pak is a first year doctoral student in George Mason University’s Clinical Psychology program, working with Dr. Sarah Fischer. She received her Bachelor of Arts in Psychology from the University of Miami in Coral Gables, FL. Naomi’s primary research interests include: 1) The influence of social media on treatment outcomes, 2) The intersection of impulsivity and emotion regulation on physiological symptomatology, and 3) Self-harm among eating disorder populations

Paige Trojanowski

Paige Trojanowski

Paige Trojanowski graduated from The Ohio State University with a B.S. in Neuroscience in Spring 2016 and is a first year graduate student in the Fischer Lab. Her research interests focus on eating disorders, excessive/compulsive exercise, and the influence of social media on disordered eating behavior and body-esteem. Additionally, she intends to use fMRI imaging to better understand the impact of biological differences among individuals presenting with various eating disorders.
