June 2022: The first edition of top scientists ranking for medicine was published by Research.com, one of the major websites for medicine research offering credible data on scientific contributions since 2014. The ranking contains h-index, publications and citations values collected on Dec. 6, 2021. For the discipline of medicine, over 65,743 profiles were examined. The inclusion criteria for scholars to be considered into the ranking of top scientists are based on the discipline h-index, proportion of the contributions made within the given discipline in addition to the awards and achievements of the scientists. The discipline h-index threshold for listing top scientists is set as an increment of 10 depending on the total number of researchers estimated for each discipline whilst ensuring that the top 1% of leading scientists are considered into the ranking. Three members of DDC leadership, Hashem El-Serag, M.D., M.P.H., Fasiha Kanwal, M.D., M.S.H.S., and David Graham, M.D., were identified as the top scientists in Medicine.

With the start of its 16th year, the TMC Digestive Diseases Center has some exciting announcements. In an effort to meet the increasing demands of members and provide access to state-of-the art research through our cores, the DDC has launched the Gastrointestinal Experimental Model Systems Core (GEMS). Formerly the Integrative Biology Core, the GEMS Core is organized to encompass an enteroid/organoid subcore and a gnotobiotic subcore. This core offers turnkey access to organoids/enteroid technologies to researchers, including samples (enteroids, organoids), reagents (specialized growth media, etc.), training, and consultative expertise. The core also provides access to Baylor Gnotobiotic Rodent Facility and animals, training and consultative expertise. With the launch of the GEMS Core, researchers have access to enteroid and organoid services as well as an advanced germ-free rodent facility
The new GEMS Core will be led by Director Noah Shroyer, Ph.D., associate professor gastroenterology and hepatology at Baylor. Dr. Shroyer has been a longtime DDC member, and a 2005 pilot feasibility awardee. Mary Estes, Ph.D., emeritus director of the DDC and professor of molecular virology and microbiology at Baylor will serve as co-director of the GEMS Core. Alton G. Swennes, D.V.M, associate director of the Center for Comparative Medicine, will also serve as co-director. Dr. Swennes has extensive experience with gnotobiotic facility design and will offer consultation on study design and feasibility.
