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.

I realized my passion for teaching medical students and residents during my residency and chief residency at University of Oklahoma.  USC Internal Medicine has what drives me as a teacher- intellectual stimulation through a wide range of pathology.  This institution is one of the best training programs in Internal Medicine.  Our goal is to teach residents to become confident and competent doctors.  I am honored to be a part of the journey these residents take to become compassionate physicians who make a difference in the community.

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.

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.

Associate Program Director

After completing residency, chief residency and serving as Associate Program Director at the University of Texas – Houston, I wanted to continue my role in medical education in the west. Being from New York, I knew Los Angeles was where I would eventually continue my academic career (and having been a film studies major in college – the area is idyllic for its rich motion picture history). I knew that education of residents would be best at an institution where the diverse pathology was paramount, and that USC would be the ideal environment to teach clinical medicine. In addition, our institution and our patients always drive me to learn and help residents investigate the evidence behind what we do.

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 trying innovate and improve 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.


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.

I've had the pleasure of interacting with hundreds of young physicians in training during my time with the USC Internal Medicine Residency Program. Working with our tremendous residency leadership team and helping create bright and capable internal medicine physicians has been a incredible joy for me. The USC family is an excellent place for training. Fight on!

Being part of the residency life cycle and seeing our residents grow to become highly skilled and innovative health care professionals has brought great satisfaction to my professional life. It is truly exciting to be part of a training program that continues to be at the forefront of medical education and exceptional patient care. I look forward to seeing what new advances our residents and LAC+USC will contribute to the medical community.
