Andrea Barrocas, M.A.
Andrea Barrocas is from Miami, Florida, and attended Emory University in Atlanta, Georgia, as an undergraduate. She majored in psychology and Italian studies. She focused on adolescent relationship research for a senior honors thesis in psychology and expanded her learning of all-things-Italian by studying abroad in Siena, Italy, for a semester. Upon graduating, Andrea began working as a research coordinator in the Department of Psychiatry at Emory University. She worked with Helen Mayberg, M.D., on a project looking at alternate treatments for severe, treatment resistant depression. She moved to Denver to study with Ben Hankin, Ph.D., at DU as his interests nicely fit with Andrea's interests in youth and psychopathology. Andrea's master's thesis focused on the associations among temperament, stress, anxiety, and depression in youth. Now a student working toward her Ph.D. in clinical psychology at the University of Denver, Andrea has developed an interest in nonsuicidal self-injurious behaviors. She currently focuses her research on understanding these behaviors in children and adolescents, as this is rarely studied. Andrea also makes an effort to find time to enjoy other things, like yoga, photography, cooking, and her cute dog.

Lauren graduated from the University of Notre Dame in 2008 with a major in psychology and a supplementary major in pre-professional studies. She was first introduced to depression research as an undergraduate research assistant in the Cognition and Emotion Lab of Jerry Haeffel, Ph.D., which explored cognitive theories of depression in adults. After graduation she completed a year of service with AmeriCorps in St. Louis, Missouri. She then came to the GEM Lab to work as a Research Coordinator, and ended up liking it so much that she decided to stay for graduate school. Lauren is currently pursuing her Ph.D. in Clinical Child Psychology, with a special interest in information processing biases as a risk factor for emotional problems in children and adolescents.
