Research Interests: We study brain activation patterns involved in typical and impaired socio-emotional development (for example, social interaction with other people, reading people’s emotions, reacting to people’s facial expressions). In particular, we are interested in understanding factors (e.g., genetics, social, family) that affect brain function in children and adolescents without disorders, in addition to youth with autism, depression, anxiety, and irritability symptoms. To accomplish this, we use functional MRI, functional connectivity, genetic, behavioral, and neuropsychological tools. Dr. Wiggins is happy to talk with any interested students about these research topics.

Nia Alexis: Research Assistant


Career Goals: I received my B.S. in Cognitive and Behavioral Neuroscience and now plan to pursue a PhD in Social Neuroscience.  I have a deep passion for literature and academia and so I am excited to one day combine the two. My lifelong goal is to write neuroscientific literature for the general public specializing in human interactions and interpersonal relationships.  

Research Interests: Ever since I was in High School, I was drawn to the human mind and its inner workings.  This curiosity was later honed into one of interpersonal relationships and why we as people do the things we do; namely, what drives us to behave in different or similar ways? Most uniquely, I strive to learn why we fall in love and how the emotion of “love” or infatuations are coded in the brain.  Working with behavioral issues such as irritability, anxiety, and depression through a neuroscientific lens in the TEND Lab especially excites me as I feel it is a huge leap in the right direction!
