Residency Leadership


Internal Medicine - Program leadership


Eric Hsieh, MD, FACP
Program Director
Vice Chair of Education

Since starting as faculty here at USC I have always considered the strength of our program to be our faculty's unwavering commitment to teaching and our Medical Center's amazing diversity of patients and wealth of pathology. Since becoming Program Director, the Associate Program Directors and I have designed this program to utilize our University's abundance of resources to help each resident achieve their goals. With these things in mind, we believe we offer a training program that can provide any trainee with superb internal medicine training while helping to advance each person along their desired career path.


Antreas Hindoyan, MD
Associate Program Director

Great cardiovascular care is attained by a strong patient-physician relationship and access to the most comprehensive and innovative treatments. My goal is to individualize a care plan for each patient that is designed to achieve the best outcomes. The cardiovascular system is a complex and integral organ system. The importance of maintaining its health is paramount to enjoying a rich and fulfilling lifestyle.

My clinical interests include coronary artery disease, interventional cardiology, and structural heart disease to name a few. I’ve earned my medical degree from Keck School of Medicine and completed two fellowships, one in interventional cardiology, and the other in cardiovascular medicine, both at LAC+USC Medical Center. I want residents to see that LAC+USC is an excellent institution and a fantastic place to train and achieve your goals.

Sonia Lin, MD, FACP
Associate Program Director

During my chief residency, I realized my interest in medical education and passion for working with residents. Here at USC, we train our residents to be confident clinicians and inquisitive academicians, which becomes especially apparent when they continue their careers, as they are recruited to renowned institutions to work and pursue fellowship training.  Our program is constantly innovating and improving based on resident feedback.  I am excited to share with you in person all the reasons I love this program and to help you achieve your own career goals.


Andrea Lu, MD
Associate Program Director

I began my time at USC as a medical student, and quickly recognized that the diverse patient population and pathology made USC a unique place to train. My time here as a resident and chief resident reaffirmed how dedicated the leadership is to creating the best learning environment for our trainees. The program continues to expand and innovate, and yet the same factors that attracted me to this residency remain – the hands-on training, the ample research opportunities, and the exceptional mentorship provided by faculty. I am excited to be part of a program that offers so many opportunities for our residents to help them reach their goals.


Joshua Sapkin, MD
Associate Program Director

As an Associate Program Director I get to witness the transformation of bright and eager interns into self-assured clinicians through their unparalleled clinical experiences, educational curriculum and research opportunities. By the end of residency, they are poised for their future endeavors, be it fellowship, private practice, academic medicine or something entirely novel. Whether it's teaching on the wards, creating new curriculum or just sitting down to talk with some of the house staff, I enjoy being a part of this process.

Patrick Sarte, MD, MS, FAAP, FACP
Associate Program Director

The USC Internal Medicine Residency Program fosters an environment for our trainees to develop individualized autonomy under the guidance of excellent teaching faculty. For these reasons in addition to the breadth of pathology and learning opportunities available at this facility, I chose to train here myself. I stayed as faculty so that I can contribute to improving further the operational and educational aspects of the hospital and training program. I remain here because I enjoy teaching both the residents and medical students, and I continue to learn from them and our patients on an almost daily basis. At USC, I have personally been able to make a difference in the lives of my patients as well as my trainees whom I have witnessed develop into confident and independently capable physicians.



Rajkumar Dasgupta, MD, FACP, FCCP
Assistant Program Director

I completed my residency at Michigan State University, Pulmonary/Critical Care fellowship at Columbia University, Saint Lukes & Roosevelt Hospital and Sleep Medicine fellowship at Henry Ford Hospital. After my training, I worked at Abington Hospital which is affiliated with Temple and Drexel University. There I was given the wonderful opportunity to work with fellows, residents and medical students. Here at USC, I love being involved with the residency program and teaching the house staff. I am an active clinical researcher and currently teach USMLE Step 1, 2, 3, and Internal Medicine Board Review around the world for the past 10 years. I look forward to meeting you all and discussing all the amazing opportunities USC has to offer.

As Med/Peds Residency Program Director, I am honored to support our residents in setting and reaching their professional and academic goals. The wide scope of pathology present in the diverse population at USC makes this an excellent place to train. Our goal is to support our residents as they go through the program and graduate as self-assured physicians with vast experience.

After completing my residency here at LAC+USC Keck Medical Center of USC, I stayed on as chief resident and enjoyed supporting the program and incoming Med Ped residents. My primary care focus is on socially and medically complex people of all ages and LGBTQ+ populations. This program and the leadership provides a diverse learning environment that allows residents to explore the many options in medicine.
