After an outstanding performance in medical school she joined Stanford for residency, where she has been a leader and a star from day one – winning the peer-nominated Julian Wolfsohn award as an intern for Outstanding Performance in Internal Medicine, being an elected Class Representative for each of her years as a resident, and pursuing research with Drs. Paul Wang, Fatima Rodriguez, and Alex Sandhu. Elena is universally recognized for her professionalism, positivity, and teamwork. After her Chief Resident year, Elena plans a career in Cardiology.


Sarah Waliany, MD

Sarah Waliany graduated from USC magna cum laude with a B.S. in Biological Sciences, and was awarded the Presidential Scholarship from USC for all 4 years of her undergraduate education.  She then enrolled at Stanford, where she earned both her M.D. and M.S. in Epidemiology and Clinical Research.  She was a superb medical student, including earning induction into the Gold Humanism Honor Society, and demonstrated superb research productivity while working in the field of CardioOncology with Drs. Joel Neal, Sandy Srinivas, Jason Gotlib, Sid Jaiswal, Han Zhu, and Ron Witteles.  She has been an outstanding clinical resident, while simultaneously continuing extraordinary research productivity during residency.  She is a recipient of the Stanford TRAM Grant, has authored 14 total peer-reviewed publications, and has published two first-author manuscripts in JACC: CardioOncology during her time as an Internal Medicine resident.  After her Chief Resident year, Sarah plans to pursue fellowship in Oncology, and she ultimately plans a career in Thoracic Oncology.
