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. Dr. Hartnett is a Fellow of the American College of Surgeons (FACS) and a Silver and Gold Fellow of the Association for Research in Vision and Ophthalmology (FARVO). -

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.
