Research Description
R. Daniel Beauchamp, MD, is the John Clinton Foshee Distinguished Professor of Surgery. He served as Chairman of the Section of Surgical Sciences, and Surgeon-in-Chief of Vanderbilt University Hospital from July 2001 through June 2018. He has been a full-time faculty member at Vanderbilt since December 1994. He holds joint appointment as professor in the department of Cell and Developmental Biology. He also served as Deputy Director of the Vanderbilt-Ingram Cancer Center from 2011 to 2019 and serves as Gastrointestinal Cancer Program Co-Leader since 2014. He was appointed Vice President for Cancer Center Network Affairs in 2018. Dr. Beauchamp has had longstanding funding support for his research from the NIH, and co-leads one of the main projects in the GI Cancer SPORE. Dr. Beauchamp's primary area of research interest has been in colorectal carcinogenesis, the biology of cancer cell invasion and metastasis, and in the identification of novel molecular biomarkers and therapeutic targets in colorectal and other alimentary tract malignancies. He applies molecular genetics, chemical biology and cell biological approaches to examine mechanistic questions in cancer biology in human tissue samples, 2D and 3D cell culture and mouse models. In addition to the basic cancer research Dr. Beauchamp works in collaboration with his Medical Oncology and Radiation Oncology colleagues to accrue cancer patients to approved clinical trials. He has trained and mentored numerous junior faculty members, physician scientist fellows, medical students, graduate students and post-doctoral fellows in his laboratory. He is a member of the American Society for Clinical Investigation, the National Academy of Medicine and a fellow of the American Association for the Advancement of Science.

Available Postdoctoral Position Details
Posted: 5/6/2019

A post-doctoral position is available to explore the relationship between IBD and colitis-associated carcinoma. We have found that TGFbeta family signaling both suppresses inflammatory response genes within colon epithelium and suppresses progression from chronic inflammation to colitis-associated carcinoma. A position is available that provides considerable flexibility in exploring this clinically relevant pathway. Projects can readily be tailored to the career needs of the applicant. Possibilities include single cell sequencing to understand the progression of this disease at a molecular level, ChIP-seq to understand how SMAD proteins can suppress inflammatory genes while inducing metabolic genes, CyTOF to understand inflammatory responses and regulation of signaling cascades, and using different mouse models of chronic inflammation/IBD to understand the most critical pathways that intersect with TGFbeta signaling to promote or inhibit tumorigenesis. We have a diverse interdisciplinary group, so strong communication skills and the ability to work collaboratively are a must. Due to the cutting-edge nature of the project, a working knowledge of bioinformatics and biostatistical analytical tools including R software is required. Experience with mouse models and organoid culture is desirable. For further information, contact Dan Beauchamp MD (Daniel.beauchamp@vumc.org) and/or Anna Means PhD (Anna.means@vumc.org).
