Dr. Casas' research interests focus broadly on the cultural contributions to cognition and brain development, and her postdoctoral work is funded by a fellowship in Interdisciplinary Studies of Culture and Neuroscience from the Foundation for Psychocultural Research (FPR). Previously, Dr. Casas has been supported by funding from the National Science Foundation’s (NSF) Graduate Research Fellowship Program and the American Psychological Association’s (APA) Diversity Program in Neuroscience.

In addition to her research, Dr. Casas also provides clinical neuropsychological services to patients with various types of brain injury. Her specific expertise is in neuropsychological assessment of cultural and linguistic minorities, including patients with limited English proficiency (LEP).
