Clinical investigation in the Division of Geographic Medicine and Infectious Diseases is a well-established and growing area of research, representing a wide variety of projects, such as epidemiologic studies, clinical trials, translational research and outcomes and modeling studies. Active areas of inquiry include:
The study of Shiga toxin-producing E. coli (e.g., O157:H7), with the overarching goal of understanding how Shiga toxins cause severe diseases in the human host, such as hemolytic uremic syndrome (HUS). We are using “mini-guts” to better understand how these bacteria and their associated virulence factors affect the host intestinal tract, and to dissect the steps by which Shiga toxin traverses the intestine to gain access to the systemic circulation.

Dr. Rakhi Teena Kohli’s research interests focus on metabolic complications of HIV infection. She has published on the effect of metformin on insulin resistance and abdominal fat in HIV-infected persons and received a NIH K23 award to examine insulin resistance and body fat changes in HIV-infected persons. Relevant Publications:
Dr. Laura Kogelman has been a site PI for several multinational multi-center HIV clinical trials, and has collaborated on several clinical HIV and Travel Medicine studies, including NIH and NIMH funded projects. HIV research projects have included those looking at tools for medication adherence both for HIV medications as well as PrEP. She has also been part of the teams engaged in COVID-19 treatment protocols. Last 3 publications:
Dr. David Stone–HIV infection in the incarcerated population; HIV infection in substance users; adherence to HIV therapy; HIV and hepatitis C co-infection.
Dr. Ramnath Subbaraman–Reasons for patient losses in the TB care cascade in India, digital technologies to support adherence to TB medications, social determinants of health in urban slum communities in India.
Dr. Cheleste Thorpe– The study of how antibiotic treatments perturb the host intestinal microbiota, and the critical metabolic functions that are lost as a result of these perturbations. I have been particularly interested in how different treatments for C. difficile affect the microbiome, and influence the risk of recurrence. I am also interested in understanding how antibiotic treatments that are highly microbiota-damaging may promote the acquisition of drug-resistant organisms. This project is a collaboration with Dr. Kyongbum Lee at Tufts University in Medford, MA, and Dr. David Snydman in our ID division.
C. difficile epidemiology and antimicrobial resistance: I collaborate with Dr. David Snydman on the epidemiology of C. difficile infection, with specific attention to the monitoring of C. difficile antibiotic resistance patterns, and determining which ribotypes are circulating at a given point in time.
