Melissa Ann Vogelsong
Clinical Assistant Professor, Anesthesiology, Perioperative and Pain Medicine
BioDr. Vogelsong is a Clinical Assistant Professor at Stanford University where she is involved in clinical work, education, and research. She completed her residency and dual fellowship training in Adult Cardiothoracic Anesthesia and Critical Care Medicine at Stanford and now attends in the Cardiovascular Intensive Care Unit (CVICU), Medical ICU, and cardiac ORs. This clinical work continuously reveals the ability of modern medicine to overcome seemingly insurmountable injury and illness, yet she believes that optimal care helps a patient to return to the highest level of functioning possible. Thus her research centers around finding ways to optimize the care of critically ill patients, particularly those supported on mechanical circulatory support and those who have suffered cardiac arrest. She has received funding from the Zoll Foundation and is actively engaged with the American Heart Association and Extracorporeal Life Support Organization.
Additionally, Dr. Vogelsong serves as Associate Medical Director for Life Flight, Stanford's air medical transport service and the only hospital-based flight program in California. She is actively engaged in efforts to enhance the provision of critical care within Stanford Hospital, and serves on multiple committees including the Medical Emergency Response Committee (MERC), ECMO Task Force, and CVICU Continuous Quality Improvement group.
When not at work, Dr. Vogelsong is a huge fan of life in California and can often be found hiking, on a mountain bike, in her Sprinter van, or talking to her many goats, llamas, and horses. -

Andre Thien Vu
MD Student, expected graduation Winter 2029
BioMy name is Andre Vu, and I am currently an MS1 at Stanford School of Medicine. Growing up in Little Saigon as a child of Vietnamese refugees, I have always felt deeply connected to my cultural heritage and community. This background has fueled my passion for addressing health disparities, particularly in underserved populations.
My interests lie in improving health disparities and fostering innovation within the healthcare sector. I believe that finding creative solutions and equitable resource distribution are crucial for improving health outcomes in marginalized communities. Outside of my academic and professional pursuits, I have a deep love for cooking Vietnamese cuisine. It is a way for me to stay connected to my roots and share my culture with others. I also enjoy expressing my creativity through painting and sculpting, which provide a wonderful balance to my studies and allow me to unwind.
I am committed to using my medical education to meaningfully impact healthcare accessibility and quality, and I am excited to be part of a future where every individual has the opportunity to achieve optimal health. -

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.
