Recent Honors:



Chase Shankula 

Chase is a 2nd 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

Kyle Baacke is a 2nd year doctoral student studying psychology at UWM with an emphasis in Neuroscience. He graduated with a B.A. in Psychology and a minor in Neuroscience from Knox College in 2016, where he worked with Dr. Andy Hertel investigating the correlates of nicotine and alcohol addiction. Following his time at Knox College, Kyle worked as a data systems analyst in the Cannabis retail industry where he developed and maintained scalable cloud-based e-commerce solutions. Kyle recently earned his M.S. in Psychological Science from the University of Illinois at Urbana-Champaign (UIUC) as a member of the Decision Neuroscience Lab directed by Dr. Aron Barbey and the Cognitive and Affective Neuroscience of Psychopathology (CANOPY) Lab directed by Dr. Wendy Heller. During his time at UIUC, Kyle collaborated on two projects for the Defense Advanced Research Projects Agency (DARPA) that utilized advanced statistical predictive modeling techniques and approaches: Teaching AI to Leverage Overlooked Residuals (TAILOR) and Measuring Biological Aptitude (MBA). Kyle also collaborated on a variety of projects evaluating dimensionality reduction, feature selection, and data harmonization of publicly available fMRI data for use in machine learning models. Kyle’s primary interest is in understanding and predicting individual differences in cannabis use outcomes, particularly substance use disorder. His current research interest is in the integration of behavioral, neuroimaging, and multi-omics data to produce interpretable statistical and machine learning models to predict and understand the development of cannabis use disorder. To further this goal, he plans to leverage his experience in cloud computing to enable scalable and reproducible preprocessing and analysis of large-scale datasets.

Gabriella Navarro 

Gabriella is a 3rd year doctoral student studying clinical psychology at UWM with an emphasis in neuropsychology. In 2016, she graduated from Stockton University with a B.S. in Psychology and a minor in Behavioral Neuroscience. Later, she received her M.S in Psychology at Drexel University under the mentorship of Dr. Maria Schultheis in the Applied Neurotechnologies lab.

Kaitlynne Leclaire, MS

Kaitlynne is a 6th year doctoral student studying clinical neuropsychology at UWM. She graduated from the University of Massachusetts Amherst in 2015 where she received her bachelor's degree in Psychology and a minor in Political Science. Upon graduating from UMass, she worked as a clinical research coordinator at the Brigham and Women's Hospital in Boston for 2 years. She assisted with a multitude of longitudinal and cross-sectional studies in multiple sclerosis to identify clinical, radiological, and molecular markers that correlate with disease severity and progression. She also co-managed pilot studies that focused on positive psychology and cognitive remediation in this population. In her early career at UWM, she completed work with Drs. Ira Driscoll and David Osmon that focused on characterizing and detecting brain and behavior changes as early predictors of age-related cognitive decline.

Kaitlynne’s current research interests include examining cognitive development across the lifespan and how health factors may influence this process. She is interested in utilizing neuroimaging & neuropsychological methodologies to better understand these changes. Specifically, she is currently working on her dissertation which examines the association between aerobic fitness and network connectivity in the default mode network in healthy adolescents and young adults. Ultimately, upon completing her PhD, Kaitlynne aims to become a board-certified clinical neuropsychologist.

Alex Wallace, MS

Alex graduated with a Ph.D. in clinical neuropsychology at UWM, and earned his B.S. in Psychology from University of Iowa with a minor in Human Relations. After college, he worked as a research assistant in the Iowa ADHD and Development Lab and the Cognitive Brain Development Lab studying adolescent brain development, substance use, and risky behavior. As a graduate student he attended both pediatric and adult neuropsychology practicums at the Medical College of Wisconsin to help in understanding neuropsychological functioning across the lifespan. Alex is currently on predoctoral internship on the neuropsychology track at St. Jude Children’s Research Hospital at the University of Tennessee Health Psychology Consortium.
Alex’s research interests focus on the intersection between externalizing disorders, specifically in comorbid substance use and attention-deficit/hyperactivity disorder. This interest extends to how early substance use initiation and escalation affect cognition and both structural and functional brain development. Additionally, Alex is interested in how health factors, such as exercise, affect brain development of adolescents and young adults and how these changes in brain development alter neurocognition.
Alex is currently a Postdoctoral Fellow in Psychiatry for the University of California - San Diego ABCD site, and prior to was on externship at the pediatric and adult neuropsychology placement at the Medical College of Wisconsin. Alex hopes to continue to expand his understanding of neurodevelopment across the lifespan.
