Ximena Corso Díaz
Assistant Professor of Ophthalmology
Current Research and Scholarly InterestsWe are interested in unraveling the roles of RNA-binding proteins (RBPs) and regulatory RNAs in retinal development and homeostasis.
RNA-binding proteins mediate functional integration of transcriptional and post-transcriptional machineries influencing various aspects of gene expression and RNA metabolism. Several RBPs have cell-type enriched expression patterns in the retina or cause blinding diseases, however their role in retinal development and function is poorly understood. We have identified several RBPs that interact with the photoreceptor-specific transcription factor NRL and are likely involved in development and homeostasis of this retinal cell-type. We are pursuing the following lines of research:
1) RBPs in retinal development and degeneration. We will study the role of RBPs in regulating retinal development and maintaining homeostasis. We will focus on RBPs enriched in the retina, their interactions with retinal transcription factors like NRL, and their relevance to retinal diseases.
2) RBPs in R-loop regulation in the retina. R-loops are triple-stranded structures created when RNA anneals to one of the strands of the DNA duplex. R-loops have many regulatory roles during gene expression and their dysregulation can be detrimental to genome integrity. We observed that R-loops are dynamic during retinal development and identified key R-loop-associated RBPs that are enriched in rod photoreceptors and that interact with the transcription factor NRL. We will study the role of R-loops and their regulatory RBPs in retinal development and homeostasis.
3) Chromatin-associated regulatory RNAs through the retina lifespan. Chromatin-associated RNAs contribute to the dynamic regulation of gene expression, chromatin structure, and genome organization, playing essential roles in various biological processes, including development, differentiation, and disease. We will study how regulatory RNAs, together with their cognate RBPs, influence expression programs and chromatin dynamics through the retina lifespan. -

Jen Haensel
Basic Life Res Scientist, Ophthalmology Research/Clinical Trials
BioI am a Research Scientist in the Roberts Vision Development & Oculomotor Lab at Stanford University’s Department of Ophthalmology, working at the intersection of vision science, neuroscience, and experimental psychology. My current research uses eye-tracking, photorefraction, and psychophysics to study oculomotor development and visual function in amblyopia, strabismus, and concussion. I also work on developing methodology to record accommodative measurements and gaze behaviour in dynamic, naturalistic settings.
I completed my PhD in Experimental Psychology at Birkbeck, University of London (UK), where I used advanced eye-tracking techniques to study the influence of postnatal experience on social gaze behaviour. Prior to joining Stanford, I also worked as a postdoctoral researcher at the University of Bath (UK), developing empirical human-robot interaction studies to inform the ethical design of humanoid robots. -

Aubrey Hargrave
Postdoctoral Scholar, Ophthalmology
BioMy research interests are centered on ocular immunology and neuroinflammation. My long-standing interest in eye research stems from personal experience with eye disease, which has led me to explore vision research and underlies my passion for disease-centric research in order to improve quality of life for patients.
I am fascinated by the immune response and inflammation, in part because of its broad applicability to many human diseases. To this end, I am interested in developing an understanding of the interplay between the immune and nervous systems in the ocular microenvironment and my past research has allowed me to explore this interplay within diverse areas of the eye. As an undergraduate, I conducted research with Dr. Rima Mcleod to study patients with toxoplasmosis, a disease affecting both ocular and neural tissue. We created a patient database and investigated whether genotype influences the inflammatory response to the t.gondii parasite. As a predoctoral student with Dr. Alan Burns, my research focused on ocular inflammation in two cases; first, in acute inflammation following a corneal abrasion and second, in the context of systemic inflammation caused by early metabolic syndrome. I analyzed the immune response in both cases and developed methods to determine the effect on corneal nerves.
During my postdoctoral training with Dr. Alfredo Dubra, I am continuing to build on my previous training in vision science, inflammation, and neurodegeneration by using adaptive optics imaging, in conjunction with standard clinical measurements, to explore potential biomarkers in diseases such as multiple sclerosis, glaucoma, and retinal degeneration. With high-resolution in vivo adaptive optics imaging we are able to monitor changes in retinal tissues at the cellular level over time, as well as to observe minute changes in the retina with treatment during clinical trials. -
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.
Dr. Hartnett's prolific publication record includes 227 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 chair of the research advisory committees for The Macula Society and the Jack McGovern Coats Disease Foundation as well as Chair of 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). -
