Vanderbilt-Ingram Cancer Center has named Richard Peek Jr., MD, a Co-Leader of its Gastrointestinal (GI) Cancer Research Program, joining Kristen Ciombor, MD, MSCI, who assumed leadership of the program in 2025.
Peek is Professor of Medicine and Director of the Division of Gastroenterology, Hepatology and Nutrition at Vanderbilt Health, where he holds the Mina Cobb Wallace Chair in Immunology. He is an internationally recognized expert in Helicobacter pylori pathogenesis and host-microbial interactions. Peek has led the Division of Gastroenterology, Hepatology and Nutrition since 2004, during which time it has tripled in size and grown its National Institutes of Health (NIH) research portfolio to more than $11 million annually.
“I am beyond excited to be able to serve in this role for the Vanderbilt-Ingram Cancer Center and to have the opportunity to work with such an exceptionally talented and dedicated physician as Kristen Ciombor,” Peek said. “Vanderbilt-Ingram has always supported my career unequivocally, particularly when they provided pilot funding that presaged our successful P01 grant on Helicobacter pylori and gastric cancer. I am honored to take on this responsibility.”
Peek’s individual research program has been funded by the NIH for more than 30 years and includes R01 and P01 funding from the National Cancer Institute. He has been elected to the American Society for Clinical Investigation, the Association of American Physicians, the American Association for the Advancement of Science, the American Clinical and Climatological Association, and was a charter member of the NIH Gastrointestinal Mucosal Pathobiology Study Section.
He also served as chair of the American Gastroenterological Association (AGA) Council, co-editor-in-chief of Gastroenterology, as a member of the NIH National Institute of Diabetes and Digestive and Kidney Disease Advisory Council and was recently selected to be president President-Elect of the AGA World Gastroenterology Organization.
Ciombor is Associate Professor of Medicine in the Division of Hematology and Oncology at Vanderbilt, where she has been a faculty member since 2017. A board-certified medical oncologist specializing in gastrointestinal cancers, she leads multiple national investigator-initiated clinical trials in colorectal cancer. She is a co-investigator on the Vanderbilt-Ingram GI SPORE grant and leads the National Clinical Trials Network Lead Academic Participating Site grant at Vanderbilt. She also serves as chair of the Colorectal/Anal Working Group for the Eastern Cooperative Oncology Group and is a member of the NCI GI Steering Committee, among other roles.
“I am delighted that Dr. Peek has been selected to co-lead the Vanderbilt-Ingram GI Cancer Research Program,” Ciombor said. “He is a world-renowned gastroenterologist and expert in H. pylori pathogenesis and a true asset to the Vanderbilt research community. I am thrilled to work with him as we continue to strengthen the GI cancer research collaborations at Vanderbilt.”
“GI cancer incidence and mortality rates in our catchment area are worse than the national average, and screening for diseases like colorectal cancer also are lower in Tennessee than in many other states,” said Ben Ho Park, MD, PhD, the Benjamin F. Byrd Jr. Professor of Oncology and Director of Vanderbilt-Ingram. “GI cancers have been a long-standing priority of the Vanderbilt-Ingram Cancer Center, in part because of the burden of GI cancers in our area, but also because of the exceptional expertise here at Vanderbilt.
“Together, Drs. Peek and Ciombor bring deep knowledge and experience to optimize and personalize the prevention, diagnosis and treatment of GI malignancies. The GI cancer research program at Vanderbilt-Ingram will flourish under their strong co-leadership.”
