Caylin Faria
cmfaria@uwm.edu
Caylin is a 2nd year doctoral student studying clinical psychology with an emphasis in neuropsychology at the University of Wisconsin-Milwaukee (UWM). Prior to UWM, she worked at Massachusetts General Hospital (MGH) in Boston as a Senior Clinical Research Coordinator in the Dauten Family Center for Bipolar Treatment Innovation and a Clinical Research Coordinator II in the Pappas Center for Neuro-Oncology. She joined the MGH team after earning her B.S. in Psychology from Bridgewater State University (BSU) in 2020. While at BSU, she completed an Honors thesis and participated in projects in the Attention and Decision-Making lab. Caylin was also an Adrian Tinsley Research Grant awardee and interned for Rhode Island Hospital's Neuropsychology Program and Massachusetts's Positive Action Against Chemical Addiction center. Her experiences in the field of clinical psychology and neuropsychology have cultivated an interest in the brain-behavior relationship and cognitive functioning. Caylin is broadly interested in risk and resilience factors for cognitive impairment. Of particular interest is the interplay between physical fitness, substance use, and cognition. Methodologies of interest are neuroimaging, neurocognitive assessment, and biological markers. When possible, she aims to explore her interests in groups historically omitted from the literature to improve the use of assessment and intervention.

Chase Shankula

shankula@uwm.edu

Chase is a 4th year doctoral student studying clinical psychology at UWM with an emphasis in neuropsychology. In 2020, he earned his B.S. in Cognitive and Behavioral Neuroscience from the University of California, San Diego, completing a thesis under Dr. Karen Dobkins on the modeling of ruminative behavior. Upon graduating, he joined Dr. Pietro Sanna’s lab at the Scripps Research Institute to study the effects of HIV-1 viral proteins on substance use and metabolism in transgenic rodent models. He took an interest in brain development while also interning with Cortica Healthcare, where he assisted in monitoring the effects of sensorimotor therapy in children with autism spectrum disorders.
Chase is primarily interested in exploring how biological and environmental factors interact to predispose youth to risk-taking and internalizing behaviors. He aims to contribute to the development of early detection methods for these maladaptive behaviors through neuroimaging and neuropsychological assessment, aided with the integration of machine learning and complex longitudinal modeling.

Kyle Baacke
