Program Administrative Structure

Our fellowship program is uniquely embedded across the Department of Neurology, chaired by Robin Brey, MD, and the Biggs Institute for Alzheimer’s and Neurodegenerative Diseases, directed by Sudha Seshadri, MD.

The joint program offers clinical, service, and research opportunities across a broad range of neurological populations such as epilepsy, multiple sclerosis and Parkinson’s disease, in conjunction with in-depth training in differential dementia diagnosis.

The fellowship is co- directed by Jeremy Davis, PsyD, ABPP and A. Campbell Sullivan, PsyD, ABPP.

The training committee is comprised of a group of faculty members with program coordination by Monica Perryman.

Jeremy J. Davis, PsyD, ABPP

Dr. Davis is an Associate Professor Clinical in the Department of Neurology with an appointment in the Biggs Institute for Alzheimer’s and Neurodegenerative Diseases. He also serves as Chief of the Division of Neuropsychology. As a board-certified neuropsychologist, his primary clinical interests include evaluation and treatment of individuals with a history of neurologic conditions ranging from movement disorders and dementia to stroke and other cerebral insults. His research interests include performance and symptom validity in neuropsychological evaluation, clinically optimized evaluation methods, and fiscally viable practice models. He serves as co-director of the newly developed postdoctoral fellowship and is a member of the finance committee in the Department of Neurology. Dr. Davis joined UT Health San Antonio in January 2021. He was previously in the Division of Physical Medicine and Rehabilitation at the University of Utah School of Medicine from 2011 until 2020.

Brittany Cerbone, PhD

Brittany Cerbone, PhD, joined the clinical faculty as an Assistant Professor in the Department of Neurology at UT Health San Antonio in 2022 after completing her residency in clinical neuropsychology at Barrow Neurological Institute. Dr. Cerbone completed her doctoral degree at the University of Houston and pre-doctoral internship at the Phoenix VA Health Care System. Her clinical and research interests focus on older adults and neurodegenerative populations and she works with the surgical teams for movement disorders and epilepsy, conducting pre/post-surgical evaluations and Wadas. During her free time, she enjoys exploring the city with her dog, hiking and trying new restaurants.

Mitzi M. Gonzales, PhD, ABPP

Dr. Gonzales is an Assistant Professor in the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases and the Department of Neurology at UT Health San Antonio. She is a board-certified clinical neuropsychologist. She earned her Ph.D. in Clinical Psychology from the University of Texas at Austin. She completed her pre-doctoral internship at the University of Illinois at Chicago and postdoctoral fellowship in Clinical Neuropsychology (clinical research track) at the VA Northern California Health Care system. Her research broadly focuses on identifying mechanisms and biomarkers of advanced age-related cognitive decline and dementia in effort to aid timely diagnosis, prevent progression, and advance treatment discovery. Her research leverages clinical neuropsychology, structural and functional neuroimaging, and geroscience approaches. A primary aim is to understand the underlying mechanisms linking biological aging with increased dementia incidence and develop interventions that slow the rate of cognitive decline.

Johanna M. Messerly, PsyD

Dr. Messerly hails from the frozen tundra of northern Wisconsin but has found a home in San Antonio, Texas both professionally and personally. She was delighted to join clinical faculty at the UT Health San Antonio, Department of Neurology, in 2019 following completion of her fellowship in clinical neuropsychology at the South Texas Veterans Health Care. Prior clinical and academic training includes completion of a neuropsychology focused internship at the Central Arkansas Veterans Health Care System and a Doctor of Psychology degree from Nova Southeastern University. Her professional interests predominantly focus on clinical care and service both towards the UT Health infrastructure and community at large. Her clinical interests are broad and include interfacing with the movement disorders team for pre/post-surgical DBS evaluations and conducting brief cognitive screening assessments for individuals with multiple sclerosis as well as working with the older adult, neurodegenerative, epilepsy, stroke, traumatic brain injury and autoimmune populations. She is passionate about connecting patients to ancillary clinical services for optimization of mental health and quality of life as well as using neuropsychological evaluations as a stepping stone for intervention.

A. Campbell Sullivan, PsyD, ABPP

Dr. Sullivan is an Assistant Professor in the Glenn Biggs Institute for Alzheimer’s and Neurodegenerative Diseases and the Department of Neurology at UT Health San Antonio. Dr. Sullivan earned her Psy.D. in Clinical Psychology from the PGSP-Stanford Consortium. As a graduate student, she developed an interest in young-onset dementia syndromes and structured her pre-doctoral internship at the University of Maryland-Baltimore VA Consortium and postdoctoral fellowship at Johns Hopkins School of Medicine to focus on the cognitive assessment of rare neurodegenerative diseases. Dr. Sullivan manages the MIND and ALS clinics, and she works closely with the Aphasia Lab at UT-Austin. Dr. Sullivan’s research endeavors include translational research targeting tauopathies and developing cognitive biomarkers for patients with prostate cancer. Outside of work, Dr. Sullivan enjoys spending time with her family.

Amy E. Werry, PsyD

Dr. Werry earned her doctorate in Clinical Psychology from Pacific University in Oregon. She completed her pre-doctoral internship at the University of Texas Health Science Center in Tyler and postdoctoral fellowship in Clinical Neuropsychology at Dartmouth-Hitchcock Medical Center and Geisel School of Medicine at Dartmouth College. Amy enjoys a broad clinical practice within the neurology clinic. Her research focus has historically been in evaluating different neuropsychological test norming practices, with a primary aim to align neuropsychological practices with socially just and culturally appropriate testing and norming. Outside of work, Amy loves to travel and spends as much time outdoors as possible, typically playing tennis, hiking, mountain biking, and kayaking.
