Science of Personality, Addiction, and Religion Throughout Adulthood

The SPARTA lab (Science of Personality, Addiction, and Religion, Throughout Adulthood) at Bowling Green State University is comprised of myself, my current graduate students, and a number of undergraduate students. At this point in time, our research group has several lines of research in various stages of development. Current projects include studies of spirituality and Tantra, examininations of pathological gambling and religious and spiritual wellbeing, examinations of the process and effects of leaving a religious group, studies of sexuality and spiritual functioning, and studies of how self-perception influences one’s interpretation of their own behaviors. Current graduate student members of our lab include Brandon Gordon, Jenny Grant, Joel Engelman, Shanti James, Brinna Lee, and (as of Fall, 2019) Camille Hoagland.

We are hoping to add one additional graduate student lab member for the Fall of 2020. If you are interested in applying to work with us in the SPARTA Lab, information on applying to BGSU’s clinical psychology PhD program is available here:

Please note, the deadline for application is December 1st, 2019.
