I am a Ph.D. candidate in Dr. Johnna Swartz's Brain Development, Psychopathology, and Mental Health lab. I graduated from Temple University in 2019 with a bachelor's degree in Psychology and a minor in Cognitive Neuroscience, after which I worked as a research assistant at Temple on projects investigating memory development in young children as well as how the cerebellum contributes to affect regulation. My research interests include the neurobiological correlates of developing mood disorders in adolescents and young adults, and how individual contexts shape risk for and resilience to psychopathology. Currently, my dissertation research uses functional magnetic resonance imaging (fMRI) to examine how reward-related brain function is related to peripheral inflammation in the body and symptoms of depression and anhedonia over time in Brazilian adolescents, as well as how sociodemographic risk for depression influences these associations. 

In my free time, I like to try new recipes, spend time outdoors, and read.
