Pulmonary & Critical Care Fellows

T32 Research Fellow

Ana Pacheco-Navarro, Mass General

Medical School: Weill Cornell Medical College
Residency: Massachusetts General Hospital
Bio: Dr. Pacheco-Navarro originally hails from Santa Cruz, California, but spent the majority of her life moving progressively further East: first to the border town of El Paso, Texas, where she spent most of her childhood, then to Massachusetts, where she studied biology and English at Williams College.  Following graduation, she spent three years teaching high school biology and physics as a Teach for America Corps member in New York City, and carried her love of education with her to medical school at Weill Cornell Medical College, where she served as her class’s education representative and was involved in designing the medical school’s new curriculum.  She attended residency at MGH, where she continued to be involved in medical education, and where she first fell in love with pulmonary and critical care medicine.  She is delighted to return home to the Bay Area for fellowship at Stanford, where her interests include translational research in acute lung injury and increasing diversity and inclusivity in medicine.  When not in the hospital, she can be found outside on the trail, enjoying a hike or a run with her dog, Summer, and her partner, Pet.
Why Stanford? "Stanford is the ultimate choose-your-own adventure fellowship: if you have an interest (either clinical or research-based), the PCCM leadership will work with you to design the second and third year to meet your needs.   Faculty are clinically excellent, incredibly friendly, and very available to meet with fellows to discuss research and career planning, and most importantly, the Stanford fellows are a wonderful group of people to both work and hang out with, in or out of the hospital."
