Ben Bellet

Ben graduated from the United States Military Academy in 2010 with a B.S. in Kinesiology, served a U.S. Army officer, for 5 years, and earned his M.S. in General Psychology at the University of Memphis in 2017.  He is interested in how humans make meaning of trauma and bereavement, and how such meaning-making processes contribute to both symptoms and positive outcomes.  His current research focuses on trauma survivors who “self-trigger,” or seek reminders of trauma in an effort to make meaning of their traumatic events.  He has also conducted research on the role of trigger warnings in the appraisal of stress and self-concept, as well as other research on the relationship between complicated grief, self-concept, and positive outcomes of loss such as posttraumatic growth.  He can be reached at, and his research is available on OSF at

Mike Osorio

Mike graduated from Amherst College in 2015 with a B.A. in Philosophy. His current research is focused on the phenomenon of retroactive jealousy and its potential links to more understood forms of psychopathology. He is currently receiving clinical training at the Center for Returning Veterans at the Boston VA, where he treats post-9/11 veterans struggling with issues of readjustment and trauma. He can be reached at

Shaan McGhie

Shaan McGhie (she/her) is a third year PhD student in Clinical Psychology. She completed her B.A. in Psychology at San Diego State University. Her research has focused on the dynamic relationships between posttraumatic stress disorder (PTSD) symptoms as investigated through network analysis. She is also investigating the hypothesis that individuals with obsessive-compulsive disorder lack insight into their internal states, through experimental work. Finally, she is interested in examining the viability of personalizing treatment using idiographic symptom networks derived from ecological momentary assessment data. She is a clinician herself and seeks to conduct research informed by this clinical practice. Outside of her research, she can be found hiking, reading fantasy, or baking. If you are interested in her work or wish to collaborate, please reach out; she aims to foster an inclusive and supportive environment with her collaborators and mentees. She can be reached at

Before joining the McNally Lab, Gabriella was a research coordinator at the University of Pennsylvania under the mentorship of Dr. Edna Foa studying the effect of estrogen on fear extinction processes among women with PTSD. She completed her MA at Teachers College, Columbia University in 2020 and her BS at the University of California, Davis in 2017.
