Chief Residents Announced for 2026-2027

Each year, the Internal Medicine Residency Program leadership selects four Chief Residents from a highly competitive group of outstanding PGY-2 residents.

We are excited to share that the class of 2026-27 Chief Residents have been announced: Evan Beiter, Faraah Bekheet, Eduardo Perez Guerrero, and Morgan Shannon.

 "Chief residents are the heart and soul of the residency program", says Ron Witteles, MD, professor of cardiovascular medicine and program director for the internal medicine residency training program. "Working with the Chiefs every year is one of the best parts of being Program Director, and I couldn’t be more excited for the opportunity to work with this incredible group and can’t wait to see all they will accomplish.”

Meet the Chief Residents

Evan Beiter

Evan Beiter earned a B.A. in Neuroscience from Washington University in St. Louis, where he served as a chief for the student-led EMS team. After graduation, he continued to work as an EMT in Colorado before pursuing his MD at Harvard Medical School. During medical school, Evan cultivated a strong interest in the history of medicine and medical education. He also earned his MBA from Harvard Business School, where he served as the president of the MD/MBA class. In business school, he was named a Kaplan Life Sciences Fellow, which allowed him to explore his interests in biotechnology and entrepreneurship, particularly within genetic engineering and drug development. At Stanford, he’s continuing these interests through work on early-stage clinical trials in oncology. Evan has also been involved in teaching as a Practice of Medicine preceptor and has enjoyed mentoring medical students. Outside of the hospital, he enjoys snowboarding, basketball, and golf. After his Chief Resident year, Evan plans to pursue fellowship training in Hematology/Oncology.

Faraah Bekheet

Faraah Bekheet was awarded the prestigious Ronald Hammond Scholarship to complete her BS in Chemistry and Economics at the University of Miami, where she contributed to research in computational biochemical methods for drug discovery. Prior to matriculating at Johns Hopkins University School of Medicine, she coordinated late-stage clinical trials for major pharmaceutical companies. At Hopkins, Faraah furthered her commitment to medical innovation through research in plastic and reconstructive surgery, including the development of a novel microsurgical device. She was also selected as a Therapeutic Development Fellow on the venture capital team at Sands Capital, where she developed a strong interest in oncology. As a resident at Stanford University, she is pursuing research in emerging oncologic therapies, including anti-regulatory T cell strategies, through the department of Early Drug Development. Her excellence in internal medicine was recognized with the peer-selected Wolfsohn Award for Outstanding Performance during her second year. Following her Chief Resident year, Faraah plans to pursue a fellowship in Hematology/Oncology with a long-term goal of contributing to breakthrough cancer treatments.

Eduardo Pérez-Guerrero

Eduardo Pérez-Guerrero earned a B.S. in Biology with a minor in Public Service and Administration from Villanova University. A native of Puerto Rico, he returned home for medical school at the University of Puerto Rico, where he was inducted into the Alpha Omega Alpha honor society and graduated summa cum laude. Aspiring to a career in cardiology, Eduardo focuses his research on harnessing emerging technologies to broaden access and improve the quality of cardiovascular care. His work seeks to increase Hispanic representation in clinical trials, improve care for patients with limited English proficiency, and expand services for underserved communities. At Stanford, Eduardo serves as the Graduate Medical Education recruitment chair for the residency diversity committee, represents his program at the Fair Oaks Health Center, and is a scholar in the Leadership Education in Advancing Diversity Program. He is spearheading the creation of a resident curriculum in digital health and artificial intelligence, and he collaborates with the Apple Heart Study team on post-hoc analyses of wearable-derived cardiac data. Through these roles and his ongoing research, Eduardo strives to foster an inclusive, tech-enabled healthcare landscape that benefits patients from all backgrounds.

Morgan Shannon

Morgan Shannon earned her B.S. in Biology from Davidson College, graduating magna cum laude and a member of Phi Beta Kappa. During her undergraduate years, she was a four-year letter winner on the varsity volleyball team and received research awards in both the Biology and Neuroscience departments. She then spent three years as a research assistant in Maria Lehtinen's developmental neurobiology lab at Boston Children's Hospital, resulting in several first-author publications. She then enrolled in medical school at Vanderbilt University in 2019. In medical school, she grew her interests in medical education, translational research, and peer mentorship, serving in leadership roles on the Student Technology and Wellness Committees and was awarded the Albert Weinstein Prize in Internal Medicine. She matched into Internal Medicine at Stanford in 2023. During residency, Morgan conducted research on the clinical significance of measurable residual disease detection in AML under the mentorship of Dr. Gabriel Mannis and has been consistently involved in teaching opportunities within the Practice of Medicine curriculum at the medical school. After her Chief Resident year, Morgan plans to pursue fellowship training in Hematology/Oncology.
