Mary Elizabeth Hartnett, MD
Michael F. Marmor, M.D. Professor of Retinal Science and Disease and Professor of Ophthalmology
BioMary Elizabeth Hartnett, MD, is the Michael F. Marmor, M.D. Professor in Retinal Science and Diseases and is a Professor of Ophthalmology at Stanford University. Dr. Hartnett is the director of Pediatric Retina at Stanford University and principal investigator of a retinal angiogenesis laboratory, in which she studies causes and treatments for diseases including retinopathy of prematurity and age-related macular degeneration. She created the first-ever academic textbook on the subject, Pediatric Retina, in its third edition, which has proven to be an invaluable resource for residents and ophthalmologists internationally.
Dr. Hartnett’s NIH-funded laboratory of vascular biology and angiogenesis has studied mechanisms causing pathology in age-related macular degeneration (AMD) and retinopathy of prematurity (ROP). Her work in AMD has been to understand the mechanisms involved in activation and invasion of choroidal endothelial cells anterior to the RPE in order to maintain vasculature that is physiologic and not damaging beneath the RPE. Her lab has elucidated environmental stressors that lead to scarring in the macula for which no vision improvement is currently possible. The goal is to find methods to prevent the scarring.
Her lab’s work in ROP provided the proof of concept to regulate an angiogenic signaling pathway by inhibiting VEGF to facilitate intraretinal neovascularization as well as to inhibit abnormal extraretinal neovascularization and reduce retinal destruction used in previous treatments. Her work has been translated through clinical trials to lead to new treatments for severe ROP and has represented a paradigm shift in the understanding and treatment of severe ROP.
Dr. Hartnett has received numerous awards, including the Weisenfeld Award, the highest award for clinician-scientists given by the Association for Research in Vision and Ophthalmology (ARVO), in 2018, and is an ARVO Gold Fellow. She received the 2019 Paul Kayser/Retina Research Foundation Global Award, the Macula Society’s 2016 Paul Henkind Award and its 2019 Arnall Patz Medal, the Paul Kayser/RRF Global Award from the PanAmerica Society, and the 2021 Suzanne Veronneau-Troutman Award, the most prestigious award from Women in Ophthalmology. In 2022, she was one of six at the University of Utah to receive a distinguished research award, for Pediatrics and Ophthalmology. In recognition of her lifetime contributions, she was inducted into the Retina Hall of Fame and was elected to the Association of American Physicians in 2025.
Dr. Hartnett's prolific publication record includes 295 articles in peer-reviewed journals and over 40 book chapters. She has delivered numerous national and international invited lectures. Her long list of professional committee work includes serving as chair of the Publications Committee of ARVO, as a mentor for the ARVO Leadership Development Program, and in leadership positions internationally as the Treasurer for The Macula Society and the Chair of the Jack McGovern Coats Disease Foundation as well as the Credentialing Committee for The Retina Society. She reviews manuscripts for more than 20 eye and science journals and serves on the editorial boards of PlosOne, Molecular Vision, and the American Journal of Ophthalmology.

Grant Hartung
Affiliate, Rad/Radiological Sciences Laboratory
BioMy research includes developing custom mathematical models and algorithms to comprehensively simulate the biophysics underlying brain dynamics. These models are then used to simulate the detailed blood flow, volume, and oxygenation changes that accompany neural activity with a focus on detailed, realistic microvascular geometry to predict the impact of hemodynamic states and vascular structure on fMRI signals (for BOLD and non-BOLD sequences). This interdisciplinary work includes advances in mathematics, biophysics, neuroscience, and computer science to enable simulations of vascular structures orders of magnitude larger than previously possible in only a few hours.
These advancements have led to the quantification of many fMRI biases previously overlooked or undervalued. This includes the geometric blurring by the capillary bed between the site of neurovascular coupling and the venous response, ultimately measured by BOLD. Moreover, the microvascular blood volume at resting-state gave a non-neuronal explanation for the mid-cortex “bump” observed in layer-fMRI BOLD signals. This tool also proposed mechanistic explanations underlying the BOLD frequency nonlinearity observed during oscillatory stimulus. In non-BOLD acquisitions, these tools discovered artifacts in IntraVoxel Incoherent Motion (IVIM) and VAscular Space Occupancy (VASO) signals caused by vascular structural and flow asymmetries and velocity heterogeneity which help explain discrepancies in experimental findings with these methods.

John P. Hegarty II
Clinical Assistant Professor, Psychiatry and Behavioral Sciences
BioI am a neuroscientist and Principal Investigator of the Stanford Clinical Neuroscience (CNS) Lab in the Department of Psychiatry and Behavioral Sciences as well as Director of Neuroimaging for the Autism and Developmental Disorders Research Program at Stanford. My innovative research studies clinical aspects of cognitive and behavioral neuroscience, with a special focus on examining the neural circuitry associated with important brain-behavior relationships that may underlie different psychological and psychiatric domains in autistic children, adolescents, and adults. The ultimate goal of this research is to improve our understanding of the development of different cognitive and behavioral skills in order to develop mechanistically driven interventions that will improve precision medicine for mental health. Biologically based diagnosis and treatment are extremely limited for most psychological and psychiatric conditions but also critically needed to increase early identification and improve treatment outcomes, especially for neurodevelopmental disorders in which early intervention is the most beneficial. My early career research has primarily focused on clinical neuroscience using neuroimaging (e.g., MRI & EEG) to examine the effects of different drugs and behavioral interventions on the brain, especially for developing biomarkers for improving treatment planning and monitoring biological changes in response to single dose and clinical trials.
My primary contributions to science thus far fall within these major categories: 1) identifying the neural correlates of individual differences in cognition and behavior, 2) developing new interventions and investigating the neurobiological substrates of response to treatment, 3) examining different factors that contribute to brain development, 4) summarizing and increasing accessibility to autism-related research, and 5) methods development for neuroimaging studies. My earliest research investigated the neurobiology of alexithymia, dyslexia, and stress using structural and functional magnetic resonance imaging to test theories of the mechanisms that contribute to differences in cognition and behavior. My subsequent dissertation research, in which I began to focus on neurodevelopmental disorders, examined the neural correlates of response to beta-blockers in autistic adults and also assessed the contribution of cerebellar circuits to the autism phenotype. During my postdoctoral training, I have developed further skills for working with children in multiple clinical research settings, especially for using advanced neuroimaging approaches to examine important brain-behavior relationships. This includes a recent K99/R00 from the National Institute of Child Health and Human Development (NCT04278898 & NCT05664789) that will assess the neurobiology of restricted and repetitive behaviors in autistic children and examine the efficacy and target engagement of a novel nutritional supplement and investigational drug, N-acetylcysteine (NAC), in the brain.
