ResearchGate Profile

Michelle was a doctoral student in the Clinical Neuropsychology program and is originally from the suburbs of Chicago. She attended the University of Wisconsin-Madison for her undergraduate degree, graduating with a double major in Biology and Psychology in 2013. During her time at UW-Madison and for the year following her graduation, she worked as a research assistant in Dr. Richard Davidson’s Center for Healthy Minds. She began graduate school at Georgia State University in 2014, working in the King Lab studying long-term outcomes of survivors of childhood brain tumors. Her work has included functional and structural neuroimaging as well as investigations of the roles played by core cognitive functions and tumor and treatment factors in higher-order functioning. She is currently completing her internship at the Minneapolis VA Healthcare System. Michelle recently accepted a postdoctoral fellowship in clinical neuropsychology at James A. Haley Veterans’ Hospital in Tampa, Florida.

Sarah Clark, Ph.D.

Master’s Thesis: Investigating Brain Networks with Insight in Adolescents at Ultra High-Risk for Schizophrenia

General Exam: Cerebellar Contributions to Proactive and Reactive Control in the Stop Signal Task: A Systematic Review and Meta-Analysis of Functional Magnetic Resonance Imaging Studies

Dissertation: Relationships between cerebello-cortical functional connectivity and executive functioning across childhood and adolescence

Sarah was a doctoral student in the Clinical Neuropsychology program and was co-mentored by Jessica Turner. She is originally from the central coast of California and attended the University of California, San Diego, graduating with a B.S. in Physiology and Neuroscience. Sarah also attended University College Dublin in Ireland, where she conducted an independent research project on concussion in contact sport and earned a Higher Diploma in Psychology. She began graduate school at Georgia State University in 2014. Throughout graduate school, Sarah has investigated resting-state functional connectivity in schizophrenia, youth at risk for psychosis, and typically developing children and adolescents. She is especially interested in how function of the cerebellum affects cognition in typical neurodevelopment, healthy adulthood, and neuropsychiatric disorders. Sarah’s dissertation is titled, “Relationships between cerebello-cortical functional connectivity and executive functioning across childhood and adolescence.” She is currently completing her internship in the Geriatric Neuropsychology track at VA Palo Alto Healthcare System. She recently accepted a postdoctoral fellowship in clinical neuropsychology at the Department of Veterans Affairs Palo Alto Health Care System, which she will begin later this year.

Sabrina Na, Ph.D.

Sabrina Na is originally from Ann Arbor, Michigan. She attended the University of Michigan and obtained her Bachelor’s of Science in Neuroscience in 2012. She received her Ph.D. in 2019 from Georgia State University in the joint Clinical Psychology and Neuropsychology & Cognitive and Affective Neuroscience programs. She completed her pre-doctoral internship at the VA Boston Healthcare System in 2019 and her postdoctoral fellowship in neuropsychology at the Emory University Department of Rehabilitation Medicine. Dr. Na is an Assistant Professor in the Department of Rehabilitation Medicine in the Emory University School of Medicine. Her clinical and research interests are in long term outcomes from acquired brain injuries (particularly brain tumor, stroke, and traumatic brain injury), as well as use of network-based neuroimaging methods to understand the mechanisms through which neurological injuries result in variability in cognitive, emotional, and psychosocial outcomes.

Alyssa Ailion, Ph.D.

Dr. Alyssa Ailion grew up in the Atlanta area and completed her undergraduate and graduate work at Georgia State University under the direction of Dr. Tricia King. She completed her APA-approved pre-doctoral internship in pediatric clinical psychology and neuropsychology at Children’s Hospital Colorado, and her APPCN postdoctoral fellowship in pediatric neuropsychology at Children’s National Medical Center in Washington, DC. Alyssa is an Attending Neuropsychologist at Boston Children’s Hospital (BCH) / Harvard Medical School in their Department of Neurology and Psychiatry, Division of Epilepsy and Clinical Neurophysiology. She will provide neuropsychological evaluations for epilepsy patients and the surgical team, as well as conduct clinical fMRI research as her primary academic focus. Her current research focuses on improving the prediction of clinical outcomes by developing and refining innovative neuroimaging methods and technologies, such as neurodiagnostic applications of clinical fMRI, improving the measurement of neural mechanisms, and understanding the complex contributions of development and treatment-related factors. Alyssa’s long-term goal is to understand how the neural mechanisms of neurological disorders, such as epilepsy, and their treatments interact with brain networks and systems more broadly to disrupt behavior and cognition. 

Kristen Smith, Ph.D.

Kristen is a pediatric neuropsychologist at Children’s of Alabama in Birmingham. She completed her PhD in Clinical Psychology at Georgia State University and completed her post-doctoral fellowship in neuropsychology and rehabilitation at the Birmingham VAMC. 

Ryan Brewster, Ph.D.

Dr. Brewster is a Clinical Neuropsychologist at the DC WRIISC.  He completed an undergraduate degree at the University of Miami and an MA and PhD in Clinical Psychology at Georgia State University.  Dr. Brewster’s training also included an internship at the University of California-Los Angeles (UCLA) Semel Institute for Neuroscience and Human Behavior and a two-year postdoctoral fellowship in Clinical Neuropsychology (Traumatic Brain Injury/Rehabilitation Track) at the West Los Angeles VAMC.  His clinical responsibilities at the DC WRIISC include conducting neuropsychological assessments of Veterans with a wide range of complex neurocognitive and emotional concerns, and supervising postdoctoral fellows specializing in neuropsychology.  Dr. Brewster’s current research interests are in the combined application of neuroimaging and traditional neuropsychological assessment to better understand TBI and epilepsy, cognitive rehabilitation following TBI, and disentangling overlapping cognitive and emotional symptoms common in mTBI and PTSD.  

Jackie Micklewright, Ph.D., ABPP-CN

After graduation, Jackie completed her postdoctoral fellowship at Mayo Clinic before attaining board-certification in neuropsychology (ABPP-CN). She currently  leads the Department of Neuropsychology at Bethesda Hospital, within the M Health Fairview System in St. Paul, Minnesota.

John Ryan, Ph.D.

After graduation, John completed postdoctoral training in Cardiovascular Behavioral Medicine at the University of Pittsburgh.  He is currently the statistical project manager for the lung transplant program at the University of Pittsburgh Medical Center.

Emily Papazoglou, Ph.D., ABPP-CN

After graduation, Emily completed a post-doctoral fellowship in pediatric neuropsychology at Kennedy Krieger Institute/Johns Hopkins Hospital. She then worked as a senior neuropsychologist at Children’s Healthcare of Atlanta. Emily now runs a private practice in Atlanta working with young children with neurological disorders. Please see
