Dr. Antonia Kaczkurkin is currently a postdoctoral fellow working at the Brain Behavior Laboratory in the Perelman School of Medicine at the University of Pennsylvania. She joined the lab in February 2015. Dr. Kaczkurkin received her Bachelor of Science degree in psychology from the University of Arizona, summa cum laude. She received her Master of Arts and Ph.D. degrees in clinical psychology from the University of Minnesota, where she was a National Science Foundation (NSF) Graduate Research Fellow. She completed her APA-accredited clinical internship at Hennepin County Medical Center in Minneapolis, Minnesota. As a postdoctoral clinician, she was funded by the Postdoctoral Fellowship for Academic Diversity Program, awarded by the Provost for Research at the University of Pennsylvania, to work with Dr. Edna Foa at the Center for the Treatment and Study of Anxiety. Dr. Kaczkurkin was subsequently funded by a National Institute of Mental Health (NIMH) Research Supplement to Promote Diversity in Health-Related Research to work with Dr. Theodore Satterthwaite at the Brain Behavior Laboratory. She was awarded a 2017 NARSAD Young Investigator Award from the Brain & Behavior Research Foundation and a Penn PROMOTES Research on Sex and Gender in Health grant from the University of Pennsylvania. Dr. Kaczkurkin is currently funded by a K99 Pathway to Independence Award from the NIMH. Dr. Kaczkurkin’s research focuses on understanding the neurobiological mechanisms that contribute to the etiology of internalizing disorders. Her specific research interests include: 1) investigating abnormal brain anatomy and functioning in anxiety and depressive disorders, and 2) understanding the neurobiological heterogeneity that exists within internalizing symptoms. In ongoing work, she integrates multi-modal imaging including task-based functional magnetic resonance imaging (fMRI), T1 imaging of brain structure, and arterial spin labeled (ASL) imaging of brain perfusion to study internalizing symptoms.
