    The Investigator Track aims to prepare the next generation of leaders in research in digestive and liver diseases. The fellowship offers up to three years of protected research training time supported by an NIH-sponsored T32 training grant. Most trainees are physicians pursuing parallel clinical training in Gastroenterology and Hepatology, which is typically accomplished with a combined curriculum of four years (1.5 years of clinical rotations and 2.5 years of research training).

    Positions are also available for postdoctoral trainees. Research opportunities offered through this track include basic research training as well as translational and clinical research in fields of relevance to digestive and liver diseases. Positions are offered to applicants with exceptional potential and a clear commitment to academia.

    NIH regulations governing the T32 training grant only allow U.S. citizens or permanent residents to participate.

    Research Training Environment

    UT Southwestern Medical Center is a premier research institution, ranked among the top research universities in the U.S. The excellence in research at UT Southwestern is reflected in the achievements of its distinguished faculty.

    With more than $167 million in NIH funding, the Medical School ranked 22nd in 2009 among peer institutions in terms of overall funding from NIH, with the Department of Internal Medicine contributing more than $40 million. The Division of Digestive and Liver Diseases itself includes 11 NIH-funded investigators and many others with active industry-funded and other clinical research.

    This academic excellence provides ample opportunities to identify appropriate mentors for fellows on the research track. Trainees pursuing an academic career in clinical research are also supported to pursue formal training in clinical research through the Career and Development Training: CTSA Program, which offers a Master of Science in Clinical Investigation degree.

    Fellowship Training Curriculum

    Physicians who enter the research track as part of their clinical fellowship in Gastroenterology and Hepatology typically devote their first year to clinical training through inpatient rotations at our three affiliated hospitals, as well as training in the outpatient setting through a weekly continuity clinic. During this time, trainees are assisted in identifying the appropriate research mentor and in formulating a proper career plan. At the end of the first year, the program offers two and a half years of protected research time, followed by six additional months of clinical rotations in the last year of fellowship, pursuant to the 18-month clinical training requirement of our ACGME-accredited program.

    Three years of work in the outpatient continuity clinic are also required. Our clinical research trainees in this track have the opportunity to train and develop clinical programs directly relevant to their research interests during their allotted protected research time. Funding is available to cover the costs of travel to relevant national meetings, as well tuition pursuant to a Master of Clinical Sciences degree.

    Obligations under the T32 Training Grant

    Participation in the T32 training grant is reserved for trainees who will pursue an academic career centered on research. During their research training, individuals enrolled in this program receive a stipend that is covered by our NIH-T32 training grant. The stipend is typically greater than that for clinical track trainees. Pursuant to NIH guidelines, this benefit incurs a payback obligation of one year of the received stipend; trainees that go on to pursue an academic career are exempt from this obligation.

    Application Process

    Applicants interested in the Investigator Track should indicate so in their ERAS application and in their personal statement. Competitive applicants will be contacted to arrange an interview date. Interested applicants are encouraged to identify investigators and potential mentors in the Medical School that they might have an interest in meeting during their interview date.

    Slots for Ph.D. scientists pursuing postdoctoral training are offered on an annual basis through an internal competition process or through external recruitment when appropriate. Applicants are encouraged to email Ezra Burstein, M.D., with specific questions about the program.

What our fellows have to say

Patrick Marquardt, M.D., Third Year Clinical Fellow

“I have loved my experience in the GI fellowship at UTSW. The exposure we get in different clinical settings including Parkland, CUH, and the VA is second to none. My co-fellows and the program leadership have been so supportive throughout the process and I really feel like I am part of a family here. I am so lucky to be part of this team!”

Sumana Reddy, M.D., Third Year Clinical Fellow

“The clinical training at UTSW is incredibly strong. It is amazing and extremely humbling to train across three different hospital systems with a diverse patient population, you will definitely see a wide variety of pathology! On top of that, we get to work with the most incredible and supportive program leadership, faculty, and co-fellows!”

Emil Thyssen, M.D., Second Year Clinical Fellow

As a brand new fellow last year, I was really nervous to start fellowship given the steep learning curve that I was anticipating from a GI fellowship. I started on one of our flagship rotations, Parkland GI consults and remember being immediately happy that I chose GI and UTSW. The camaraderie from the fellows and attendings was incredible. The upper level fellows recurrently offered to help offload me by offering to consent patients for procedures and trying to make sure that my day goes smoothly, offering tips and tricks for efficiency. Now that I’m an upper level, it’s been fulfilling to attempt to pay that forward as much as possible in hopes of cultivating a strong team environment that was laid for me. Our program is ideal for anyone who wants a broad exposure both scholastically and technically while being surrounded by a group of supportive fellows and faculty.

Ashwini Arvind, M.D., Research Fellow

“I have loved my GI training at UT Southwestern so far. We have the opportunity to serve a diverse patient population and see a fascinating array of pathologies. The program is clinically rigorous with a high procedural volume, so we quickly feel comfortable managing patients across the spectrum of GI disorders. The faculty are kind, approachable and knowledgeable, and there is an emphasis on fellow wellness. In addition, the quality of academic mentorship is superb. I am excited for what is to come!”

Aaron Fond, M.D., Ph.D., Alumni

“We have a wide diversity of experiences in fellowship because of the different sites we train at. More than anything though, this program is great because of the culture among the fellows. There is a collaborative and collegial atmosphere with everyone trying to help each other out, which makes stressful days much more bearable.”

Stuart Liu, M.D., M.P.H., Alumni

“I met some of the most supportive and nicest people in UT Southwestern. I enjoy working with my co-fellows. Everyone is willing to help out and we can always rely on each other. UT Southwestern provides training in three very different clinical settings including a well-functioning public hospital (Parkland), a private university hospital (Clements), and one of the largest VA in the country. The breadth and depth of pathology here are amazing and we are well positioned to become independent gastroenterologists. Finally, there are multiple mentors willing to help in education, career development, or research.”
