Graduate Students

Trisha Glover, M.S. –

Trisha earned her B.S. in Biology and Psychology from Pacific Lutheran University in 2018. After graduating, she went on to earn her M.S. in Clinical Psychology from the University of Texas at Tyler in 2021, and is a 2nd year in the PhD program at WSU. Her current research interests focus on the neurobiological basis of developmental disorders (primarily ADHD and ASD) and developmental psychopathology in children and adolescents from low socioeconomic areas. She is also interested in how protective factors (e.g., parent-child relationships) and risk factors (e.g., adverse childhood experiences, exposure to trauma) impact the development of psychological disorders in early life. After graduating from Washington State University, she is hoping to advance treatment availability and options for children and adolescents that have been diagnosed with ADHD and ASD.

After graduating, she worked as a lab manager at The Family Institute at Northwestern University for three years before joining WSU’s doctoral program. Callie’s research interests are in neuropsychology and disinhibition (violence, antisociality). She’s interested in translational science and using neurocognitive/neurophysiological mechanisms to inform diagnostic and treatment efforts. She hopes to become a professor and clinical neuropsychologist at an academic medical center after finishing her Ph.D. Outside of school, you will likely find Callie dog sitting, working out, or trying out a new hike!

Shelby Johnson graduated from the University of North Carolina at Chapel Hill with a double major in Psychology and Spanish and is currently in her 5th year of the Clinical Psychology PhD program. Shelby’s primary research interests include early diagnosis of neurocognitive disorders, like autism and ADHD, and how multilingualism impacts executive functioning in children. Clinically, Shelby primarily works with children for both therapy and assessment and hopes to continue in the field of pediatric neuropsychology after finishing her PhD.

Aurora Brinkman, M.S. –

Aurora is a 6th year graduate student and is currently on internship in the child track at the UAB-BVAMC Clinical Psych Internship Consortium in Birmingham, AL.

Her research centers around empowerment, stigma, expressed emotion, and other factors that relate to the behavior of children with disabilities and overall family functioning. Aurora is very passionate about disability justice, intersectionality, social justice, and advocacy. Ultimately, she hopes to become a licensed clinical psychologist who works with disabled individuals of all ages and who does policy and advocacy work to reduce mental health/disability stigma and promote service accessibility.
