Karen Wai, MD
Clinical Assistant Professor, Ophthalmology
BioDr. Wai is a board-certified ophthalmologist and fellowship-trained vitreoretinal surgeon with Stanford Health Care Byers Eye Institute. She is also a clinical assistant professor of ophthalmology in the Department of Ophthalmology at Stanford University School of Medicine.
Dr. Wai is a retina specialist who diagnoses and treats retinal and macular diseases, including age-related macular degeneration, diabetic retinopathy, retinal vascular occlusions (blockages), and retinal tears/detachments. The retina is a tissue layer in the back of the eye. It converts light into signals that the brain then interprets as images. The macula is the part of the retina responsible for central (straight ahead) vision. Diseases of the retina and macula can cause low vision and vision loss.
Dr. Wai’s research interests include working with data from electronic health record databases to improve patient outcomes. She has researched morbidity and mortality (illness and death) rates in patients with retinal vein occlusions and retinal artery occlusions. A retinal vein occlusion is a blocked vein to the retina that can cause vision loss. A retinal artery occlusion is when an artery to the retina is blocked, which is also sometimes referred to as eye stroke. Dr. Wai has also examined the effects of systemic medications on the retina. She has won several ophthalmology awards, including the Heed Fellowship and Harvard Medical School’s Excellence in Clinical Instruction Resident Award.
Dr. Wai has published in more than 40 peer-reviewed journals, including Ophthalmology, American Journal of Ophthalmology, and JAMA Ophthalmology. She has presented research at meetings and conferences around the United States.
Dr. Wai is a member of the American Board of Ophthalmology. -

Current Research and Scholarly InterestsUbiquitin signaling: structure, function, and therapeutics
Ubiquitin is a small protein modifier that is ubiquitously produced in the cells and takes part in the regulation of a wide range of cellular activities such as gene transcription and protein turnover. The key to the diversity of the ubiquitin roles in cells is that it is capable of interacting with other cellular proteins either as a single molecule or as different types of chains. Ubiquitin chains are produced through polymerization of ubiquitin molecules via any of their seven internal lysine residues or the N-terminal methionine residue. Covalent interaction of ubiquitin with other proteins is known as ubiquitination which is carried out through an enzymatic cascade composed of the ubiquitin-activating (E1), ubiquitin-conjugating (E2), and ubiquitin ligase (E3) enzymes. The ubiquitin signals are decoded by the ubiquitin-binding domains (UBDs). These domains often specifically recognize and non-covalently bind to the different ubiquitin species, resulting in distinct signaling outcomes.
We apply a combination of the structural (including protein crystallography, small angle x-ray scattering, cryo-electron microscopy (Cryo-EM) etc.), biocomputational and biochemical techniques to study the ubiquitylation and deubiquitination processes, and recognition of the ubiquitin chains by the proteins harboring ubiquitin-binding domains. Current research interests including SARS-COV2 proteases and their interactions with polyubiquitin chains and ubiquitin pathways in host cell responses, with an ultimate goal of providing strategies for effective therapeutics with reduced levels of side effects.
Protein self-assembly processes and applications.
The Surface layers (S-layers) are crystalline protein coats surrounding microbial cells. S-layer proteins (SLPs) regulate their extracellular, self-assembly by crystallizing when exposed to an environmental trigger. We have demonstrated that the Caulobacter crescentus SLP readily crystallizes into sheets both in vivo and in vitro via a calcium-triggered multistep assembly pathway. Observing crystallization using a time course of Cryo-EM imaging has revealed a crystalline intermediate wherein N-terminal nucleation domains exhibit motional dynamics with respect to rigid lattice-forming crystallization domains. Rate enhancement of protein crystallization by a discrete nucleation domain may enable engineering of kinetically controllable self-assembling 2D macromolecular nanomaterials. In particular, this is inspiring designing robust novel platform for nano-scale protein scaffolds for structure-based drug design and nano-bioreactor design for the carbon-cycling enzyme pathway enzymes. Current research focuses on development of nano-scaffolds for high throughput in vitro assays and structure determination of small and flexible proteins and their interaction partners using Cryo-EM, and applying them to cancer and anti-viral therapeutics.
Multiscale imaging and technology developments.
Multimodal, multiscale imaging modalities will be developed and integrated to understand how molecular level events of key enzymes and protein network are connected to cellular and multi-cellular functions through intra-cellular organization and interactions of the key machineries in the cell. Larger scale organization of these proteins will be studied by solution X-ray scattering and Cryo-EM. Their spatio-temporal arrangements in the cell organelles, membranes, and cytosol will be further studied by X-ray fluorescence imaging and correlated with cryoEM and super-resolution optical microscopy. We apply these multiscale integrative imaging approaches to biomedical, and environmental and bioenergy research questions with Stanford, DOE national labs, and other domestic and international collaborators. -

Virginia Walbot
Professor of Biology, Emerita
Current Research and Scholarly InterestsOur current focus is on maize anther development to understand how cell fate is specified. We discovered that hypoxia triggers specification of the archesporial (pre-meiotic) cells, and that these cells secrete a small protein MAC1 that patterns the adjacent soma to differentiate as endothecial and secondary parietal cell types. We also discovered a novel class of small RNA: 21-nt and 24-nt phasiRNAs that are exceptionally abundant in anthers and exhibit strict spatiotemporal dynamics.

Darion Aaron Wallace
BioDarion A. Wallace, from Inglewood, CA, is a Ph.D. student in the Graduate School of Education in the Race, Inequality, and Language in Education, History of Education, and Sociology of Education programs. He earned a bachelor’s degree in Rhetoric and African American Studies from the University of California, Berkeley, and a master’s degree in International Education Policy Analysis from Stanford University. As a Black Education Studies scholar, Darion’s research draws upon Black Studies, Sociology, and History, while employing mixed methods, to interrogate the ways K-12 American schools cohere logics of (anti)blackness and structure the life and educational outcomes of Black students across temporal and spatial bounds. Moreover, he is interested in how abolitionist praxes, pedagogies, and epistemologies rooted in the Black radical and intellectual tradition have and continue to serve a liberatory function in the project of Black education. To this aim, Darion is interested in partnering with public schools and libraries to develop secondary students’ historical literacies and archival skills to help them better understand the localized sociopolitical context that undergirds their lived experience. Previously, he has worked with the Learning Policy Institute as a Research and Policy Associate, the Service Employees International Union as an Organizer, and San Francisco State University as an Africana Studies Lecturer on Black Masculinities and Black Social Science.
