Daniel Lydon

St. John’s University

Daniel is a second-year clinical psychology doctoral student at St. John’s University, who has recently completed his master’s thesis research under the mentorship Dr. Raymond DiGiuseppe. Daniel initially joined APA’s Division 29 to stay up-to-date on the latest research in this ever-advancing field. Since joining, Daniel believes his membership has enhanced his graduate school experience and he wishes to share that knowledge with other students. His current research interests involve the study of aspects of psychotherapy influenced by the therapist themselves, which may sometimes interfere with their work (i.e., personal bias), with the goal of informing practitioners and helping them to overcome these barriers in treatment. More broadly, Daniel has interests in clinical health psychology, including the application of psychotherapy to physical symptoms. Daniel previously worked in a behavioral medicine setting with a team that was conducting research on evidence-based psychotherapy for side-effect management in individuals diagnosed with breast cancer. If elected chair, Daniel plans to encourage and initiate productive conversations related to how we as graduate students can play a role in advocating for societal and systematic level change, especially in regard to racial injustices.
