Melissa Ann Vogelsong
Clinical Associate Professor, Anesthesiology, Perioperative and Pain Medicine
BioDr. Vogelsong is a Clinical Associate 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. -

Ayelet Voskoboynik
Assistant Professor (Research) of Biology
Current Research and Scholarly InterestsWe study the mechanisms by which animals differentiate between self and non-self, and how stem cells and immune cells coordinate to form tissues during development, regeneration, transplantation, and aging. By leveraging the natural stem cell-mediated development, regeneration, and chimerism in the colonial chordate Botryllus schlosseri, we investigate stem cell competition and the decline in regenerative capacity during aging.

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. -
