Mentorship
Dr. Callahan’s undergraduate education was accomplished at the University of Jamestown, where she triple majored (psychology, applied music [trumpet), and music education). The legacy of her experience at UJ is evident today in the form of her deep commitment to mentorship. UJ has a student faculty ratio of 13:1 which allowed her close contact with professors who inspired and shaped her sense of self in ways that were both personal and professional. Recognized as a College Fellow, an honor bestowed on no more than two students with junior standing in a field of study annually, she was afforded academic ranking just below that of faculty for her final year of undergraduate study. Principled mentoring is key to the UJ model of education. It is also the primary method in which doctoral training in psychology is accomplished. As such, Dr. Callahan aims to bring the positive mentorship experience she enjoyed as a student to the students in her research lab.
After gaining work experience at a residential treatment center for children and adolescents, Dr. Callahan completed her masters and doctoral degrees in the Clinical Psychology program at the University of Wisconsin-Milwaukee with Dr. Mike Hynan (now retired) as her research mentor. Her thesis project contributed to the development of a measure, the PPQ-II, for assessing perinatal posttraumatic symptoms. Her dissertation examined the applicability of two models of psychotherapy to the training clinic setting, which lay the seeds for the eventual development of the work of this research lab.
Dr. Callahan’s APA-accredited internship in clinical psychology and clinical neuropsychology was completed at Yale University School of Medicine. Dr. Callahan remained at Yale for her postdoctoral training under the primary mentorship of Dr. Keith Hawkins. In addition to the clinical training afforded her (inpatient, outpatient, cognitive rehabilitation, and forensic settings), her research training involved grant-funded work focused on neurodegenerative conditions (including dementia of diverse etiologies and psychosis) and fueled a lifelong passion and appreciation of clinical neuropsychological assessment.
