Alex Wallace, PhD

alexanderlavernewallace@gmail.com/ alwallace@health.ucsd.edu

Dr. Alexander Wallace’s (https://profiles.ucsd.edu/alexander.wallace) research focuses on the effects of substance use on adolescent and young adult neurodevelopment including neuropsychological, clinical, and neuroanatomical outcomes. His work leverages both self-report and biomarkers of substance use including toxicology testing and circulating endocannabinoids. Further, by utilizing large open access datasets like the Adolescent Brain Cognitive Development (ABCD) Study, he looks at the effects of substance use on adolescent cognitive and structural brain markers beyond two time points to more comprehensive understand longitudinal trajectories. Finally, Dr. Wallace examines how modifiable health factors, such as physical activity, may moderate the relationships between substance use and development.

Dr. Wallace has recently received a K08 grant from the National Institute on Drug Abuse to research the moderating role of caffeine on adolescent caffeine use. Additionally, Dr. Wallace is the Co-Chair of the Substance Use Workgroup on the ABCD Study and helps to oversee substance use data collection across the ABCD consortium.

Dr. Wallace will be teaching Assessment and provide training in Clinical Neuropsychology in the UWM Psychological & Brain Sciences Department.

GRADUATE STUDENT RECRUITMENT NOTE (2027-2028): Dr. Wallace will be recruiting a graduate student in clinical psychology for the 2027-2028 academic year. Students will also work closely with other BraIN Lab members, including Dr. Lisdahl.

GRADUATE STUDENTS

MacKenna Shampine
shampine@uwm.edu
MacKenna is a 2nd year doctoral student studying clinical psychology with an emphasis in neuropsychology at UWM. She earned her B.A. in Psychology from Hope College in 2023, where she worked with Dr. Lindsey Root Luna to investigate the psychophysiological correlates of emotion regulation and stress. During this time, she also worked as a Psychiatric Technician at Pine Rest Psychiatric Hospital in Grand Rapids, MI. She later joined the Trauma History Investigation of Neurodevelopment in Kids (THINK Lab) at Wayne State University with Dr. Hilary Marusak, serving as study coordinator and lab manager for two years. Beyond the lab, MacKenna is an executive board member of Science Policy Network–Detroit, where she advocates for evidence-based health policy at local, state, and national levels.
MacKenna is interested in researching the psychobiological underpinnings of stress and trauma in youth, with particular interest in the intersection of physical and mental health. She aims to develop novel treatments by integrating physiological and psychological approaches to improve outcomes for stress- and trauma-related psychopathology.

Caylin Faria
cmfaria@uwm.edu
Caylin is a 3rd 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 5th 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

kbaacke@uwm.edu

Kyle Baacke is a 5th 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 Love

navarrog@uwm.edu

Gabby is a 6th year doctoral student in the Clinical Psychology program at UWM with an emphasis in neuropsychology. She earned her B.S. in Psychology with a minor in Behavioral Neuroscience from Stockton University in 2016, then completed her M.S. in Psychology at Drexel University. At Drexel, she worked in the Applied Neurotechnologies Lab with individuals affected by multiple sclerosis and stroke, applying cognitive assessment and neuromodulation approaches to improve functional outcomes. She later joined the Coatesville VA Medical Center as a research assistant and psychometrist, where she helped investigate the link between traumatic brain injury and substance use disorder in veterans. That work sparked her interest in substance use etiology and shifted her research focus toward developmental risk processes.
Gabby’s primary research interests focus on how parental substance use history shapes adolescents’ neurocognitive development and increases vulnerability to early substance use. She is also interested in identifying cognitive and environmental factors that may buffer this risk, with the goal of informing interventions that target these modifiable pathways. Her work leverages longitudinal statistical approaches and integrates neuroimaging with neuropsychological methods to identify the mechanisms underlying these outcomes. Gabby is currently completing an external practicum in adult neuropsychology at the Milwaukee VA and ultimately aims to become a board-certified clinical neuropsychologist.
