Meet the Rathmann Fellows


The Stanford School of Medicine Office of Medical Education and Research and Evaluation group are pleased to announce that Dr. Carl Gold (Neurology and Neurological Sciences) and Dr. Tyler Johnson (Oncology) have been selected as Rathmann Family Medical Education Fellows in Patient-Centered Care for 2017-18. This program provides the part-time salary support for a Stanford faculty, fellow, or chief resident to pursue further study and activities focused on the promotion of patient-centered care in medical education.

Carl Gold, MD, MS

Dr. Carl Gold graduated from Robert Wood Johnson Medical School. He completed Neurology residency at New York-Presbyterian/Columbia University Medical Center and Neurohospitalist Fellowship at UCSF. Dr. Gold is currently a Clinical Assistant Professor in the Stanford Department of Neurology & Neurological Sciences. 

   As a Neurohospitalist, Dr. Gold specializes in the diagnosis and treatment of hospitalized patients with neurological disorders. He cares for a broad range of patients, including individuals with seizures, central nervous system infections, autoimmune diseases, headaches, neuromuscular conditions, and neurological complications of cancer. Dr. Gold's interests include bedside teaching of medical students and residents, improving physician communication, and empowering trainees to design and complete quality improvement projects.

Tyler Johnson, MD

After graduating from the University of Pennsylvania medical school in 2009, Dr. Johnson came to Stanford for his internship and residency and was then selected to stay on as a chief resident in 2012.  Upon completing his chief year, he stayed again for his hematology/oncology training as a fellow from 2013-2016 and was delighted to join the faculty in the division of oncology in 2016 as a clinical assistant professor specializing in the care of patients with GI malignancies.  In the oncology division, Tyler currently helps lead the housestaff inpatient oncology service (med 10).

As Dr. Johnson progressed through his medical training, he found he loved teaching just as much as caring for patients.  Dr. Johnson has engaged in medical education at virtually all levels and in multiple forums over his eight years at Stanford medical school.  On the wards as a supervising resident, he frequently went to the whiteboard to give informal lectures on everything from inotropes to ABGs and as a chief resident he pioneered multiple novel teaching methods in daily "morning reports."  As a fellow and faculty member he has become increasingly involved in medical student education--leading small groups of early-year medical students as they develop fluency in the physical exam and clinical reasoning.  Also, while a fellow he established a program that allows for the rigorous planning, implementation, and evaluation of an annual educational intervention in the internal medicine residency program.

As a Rathmann fellow, Dr. Johnson hopes to develop a deeper understanding of how hematology/oncology fellowship programs in the United States educate their fellows by surveying the country's fellowship program directors.  He hopes to use this knowledge to improve the education of Stanford hematology/oncology fellows with a curriculum that is both broad and deep and which includes learning to deliver compassionate and high-caliber care in difficult, high-stakes, and end-of-life situations.

Program Description

The program provides protected time for one year to participation in a core curriculum in medical education theory, methods and research, participation in ongoing curriculum development in undergraduate or graduate medical education in the area of patient-centered care, and development and conduct of a scholarly project in medical education related to patient-centered care. The fellow will participate in the Educators-4-C.A.R.E. (E4C) program, serving as a mentored preceptor with selected E4C faculty in educational activities that are part of the E4C program. 

About Educators-4-C.A.R.E 

The Educators-4-C.A.R.E. program, launched in 2008, formally recognizes the critical importance of mentors and clinical teachers by providing tangible support to a cadre of skilled and dedicated teachers of the practice of medicine. As the name implies, the Educators-4-CARE program prepares students to internalize core values of the profession Compassion, Advocacy, Responsibility, and Empathy from the beginning and throughout medical school. Seventeen program faculty are supported for time to serve as teachers and mentors for a small number of students (~6) from each medical school class. After intense faculty development in principles and practice of patient-centered care, the E4C faculty formally teach bedside clinical skills to preclinical students as part of the Practice of Medicine course. In addition to these regular sessions, E4C faculty meet with their students from all years on a bimonthly basis, in the Doctoring with C.A.R.E. sessions. These interludes allow for important near-peer interactions, mentoring, and revisiting important and crosscutting issues in medical practice, with a major focus on patient-centered care. 


Please join us in congratulating Drs. Gold and Johnson for this important achievement!

She is also Co-Director of the Core Clerkship in Family Medicine at the Stanford University School of Medicine. Her professional areas of interest include a holistic approach to the practice of primary care as well as fostering authentic, patient-centered communication in the clinical setting. Her fellowship training in Integrative Medicine motivated her to examine and improve the communication between patients and their physicians regarding their use of Complementary and Alternative Medicine modalities, enhancing patient safety and allowing for more open, honest disclosure in the patient-physician relationship. Dr. Rydel has been developing a four-year, longitudinal medical student curriculum about this topic, planning to launch the curriculum in Spring 2014.


Dr. Jeff Chi is currently a hospitalist at Stanford Hospital and Clinics, and a Clinical Assistant Professor of Medicine in the Stanford School of Medicine Department of General Disciplines.  He is currently the faculty lead for the Electronic Health Record curriculum for 2nd year medical students.  His primary research interests relate to the influence of the Electronic Health Record on medical education. His Rathmann Medical Education research project: Although adoption of Electronic Health Record (EHR) is becoming more widespread, the effect of the EMR on medical education has not received significant attention.  It has been postulated that implementation of the EHR has altered trainee workflow and further predisposes the learner to spend more time occupied by indirect patient care.  This potentially has significant implications since the usage of the EHR and its features without proper training and guidance could negatively impact education and delivery of patient-centered care.  This could also impact work hour violations with housestaff.  We hope to contribute to this literature by characterizing EHR use by medical residents and students at our institution with this study, identify driving factors, and implications on performance and other outcomes. 

Dr. Dana Romalis is currently a Clinical Assistant Professor of Medicine at Stanford School of Medicine.
