Dr. Trautner’s research is focused on development of preventive strategies for healthcare associated infections. She is leading the implementation of a successful intervention that decreased unnecessary screening for and treatment of asymptomatic bacteriuria at four large health care facilities. She has been funded continuously by the NIH or the VA since 2002, and has been a co-investigator in infection prevention projects funded by AHRQ and the CDC. She is currently mentoring several junior faculty from four departments (one from the Department of Surgery who is working on identifying sustainable solutions to access problems in liver transplantation). Her addition has strengthened program’s expertise in implementation science.

Jason Hou, M.D., M.S., is an associate professor of medicine in the Section of Gastroenterology and Hepatology at BCM where he serves as the program director for the GI fellowship training program. Dr. Hou is a graduate of the BCM GI fellowship and Certified Treecare Safety Professional programs. Shortly after completing his research training, Dr. Hou received a career development award from the ACG followed by an AHRQ K23 and more recently a VA Merit Review grant as the PI. He holds important leadership positions with the AGA and Crohn’s and Colitis Foundation (CCFA). Dr. Hou’s research interest is in preventive care aspects of inflammatory bowel disease.

David Y. Graham, M.D., is a professor of medicine and molecular virology and microbiology at BCM. He serves as a co-director for the Study Design & Clinical Research Core of the Texas Medical Center DDC. He was the section chief of Gastroenterology and Hepatology at BCM (1995-2007) and past president of the ACG. Dr. Graham’s research has focused on acid peptic disease in general specifically in relation to H. pylori and nonsteroidal anti-inflammatory drug-induced gastrointestinal damage. His clinical and translational research also involves infectious agents and the intestine (e.g., norovirus infection and vaccines, Mycobacterium paratuberculosis in Crohn's disease, and C. difficile colitis). He is currently the PI for multi-center studies evaluating anti-mycobacterial therapy for Crohn's disease. His previous mentees include a number of successful investigators.

James Versalovic, M.D., Ph.D., is a professor of pediatrics at BCM. He serves as the chair of the Department of Pathology at Texas Children’s Hospital. He is also co-director of the DDC and the director of the Functional Genomics and Microbiome Core of the DDC. The group led by Dr. Versalovic has been instrumental in development of 16S rRNA gene and whole genome shotgun sequencing as part of the Human Microbiome Project (HMP) since its inception. Dr. Versalovic’ primary research focus is the translational aspects of the composition and function of the intestinal microbiome and mechanisms of signaling between the microbiome and intestinal mucosa, with a focus in chronic gastrointestinal diseases such as IBD, IBS, C difficile and gastritis. Dr. Versalovic has long track record of successful mentoring of student, post docs, resident, fellows and junior faculty. He serves as co-director of BCM NIH-funded Medical Scientist (M.D.-Ph.D.) training program, and as mentor in the NIDDK-funded T32 program training Ph.D. and M.D. investigators in pediatric gastroenterology.

He is the coordinating center PI for the Texas Hepatocellular Carcinoma Consortium (PI, El-Serag). His is the PI of the Coordinating and Data Management Group Center for the Molecular Characterization of Screen Detected Lesions Consortium, an NCI-funded consortium that develops database and biostatical solutions integrating work at academic sites, the NCI, and the NASA Jet Propulsion Laboratory. He was the U.S. leader of the OncoArray Consortium focusing on lung cancer research. The goals of the OncoArray Consortium have been to identify genetic factors for cancer susceptibility and this platform has been used for studying all common cancers with papers in Nature and Nature Genetics being published on a monthly basis from these studies. Dr. Amos has mentored 20 junior faculty who hold positions in academia and industry, 17 post-doctoral fellows and 16 predoctoral students.

Aaron P. Thrift, Ph.D., is an assistant professor of medicine in the Section of Epidemiology and Population Sciences and Research Member of the Cancer Prevention and Population Sciences Program, Dan L Duncan Comprehensive Cancer Center at BCM. The goal of his research is to develop strategies to reduce the preventable population burden of cancer. He is a member of the NIH funded Barrett’s Esophagus and Esophageal Adenocarcinoma Consortium. His current research focus is on understanding the factors (lifestyle, genetic, social, and medical care) that contribute to risk of gastrointestinal cancers and pre-cancer conditions, and using this information to identify individuals in the population at greatest risk. Further, Dr. Thrift’s research aims to understand factors that contribute to liver cancer for vulnerable racial/ethnic subgroups of the population, with the ultimate goal of reducing disparities in liver cancer incidence. He has been funded by the NIH and CPRIT as a PI, and has been a co-investigator on projects funded by the VA.
