The LSU Internal Medicine Residency in Baton Rouge

Research and Scholarly Activity


Research and Scholarly Activity


The LSU IM Residency Program encourages and provides ample opportunities for research and other forms of scholarly activity.  Our faculty’s efforts focus on clinical and translational research, medical education, and quality improvement projects. Residents have the opportunity to do a one-month research elective during the second half of their PGY-1 year, and during their PGY2 and PGY-3 years.  Current examples of our residents’ scholarly activity range from resident-led quality improvement projects to industry-sponsored clinical trials.

Our faculty’s broad array of interests and unwavering support fosters each resident’s growth as a critical thinker and establishes an environment conducive for idea development, investigation and dissemination of their findings.  This element of our program develops and enhances residents' skills in project development, implementation, composition, and submission.  Residents, in collaboration with a faculty mentor, are expected to submit at least one scholarly piece for publication or presentation prior to completion of residency.  This can be in the form of (1) an abstract or case report, (2) a journal article submitted for publication, (3) the presentation of results of a research project, or (4) the submission for publication of a critical analysis.  Several of our residents have been awarded grants for their research. For those residents who have scholarly activity accepted for presentation at a regional or national meeting, they are often sponsored by the residency program to attend the meeting.

Monitoring Ulcerative Colitis & Crohn’s with a Standardized Approach (MUCCoSA)

There is currently no standard of care for therapeutic drug monitoring in patients with ulcerative colitis, which inevitably results in variability in provider approaches to care for these patients.  Current guidelines offer broad recommendations while acknowledging there is still a need for prospective, real-world studies to reach a defined standard.  MUCCoSA aims to assess the current care of IBD patients in the community and perform studies under a framework that will help define a standard of care.  Specific projects emanating from the MUCCoSA framework include:


  • Retrospective assessment of practice patterns with infusion-based drug therapeutic monitoring in community GI practices

  • Prospective studies to define surrogates for endsoscopy and predictive markers for therapeutic response to infusion based therapeutics

  • Creation and implementation of a therapeutic drug monitoring clinical decision support tool

Bone Health during Spaceflight

Klotho is a transmembrane protein, closely linked to FGF-23, that has protective effects against several pathologic states including vascular dysfunction, fibrosis, inflammation, bone loss.  Many of these pathologic states are known to develop when tissues are exposed to hazards that are present in the spaceflight environment such as low dose radiation and microgravity.  For these reasons, we know that the Klotho-FGF23 axis is a novel endocrine link between bone, kidney, and vascular health in astronauts.  Our findings from this preliminary study of Klotho concentrations in mice subjected to a weightless environment on the International Space Station will serve as the basis for a proposal to directly measure this axis in astronauts and correlate these measurements with altered homeostasis experienced in prolonged zero gravity.
