Launch of Gastrointestinal Experimental Model Systems Core (GEMS)

Item Definition

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.

Dr. Fasiha Kanwal is Next Editor-in-Chief for Clinical Gastroenterology and Hepatology

Item Definition

Dr. Fasiha Kanwal has been selected by the AGA to serve as the next editor-in-chief for their premier clinical journal "Clinical Gastroenterology and Hepatology CGH}" (2017-2022). Dr. Kanwal is the co-director of the Study Design and Clinical Research Core in the DDC and director of clinical research in the Section of Gastroenterology and Hepatology at Baylor College of Medicine.

This choice is significant as well as historical in several respects. It was a competitive process with other applications from leading institutions; Dr. Kanwal's application was reportedly heads and shoulders above all else. CGH is a high impact journal (IF 7.7). This is the first time that two successive editor-in-chiefs for a major GI journal come from the same institution; Dr Aaron Thrift from our section will also serve as the statistical editor for the journal. Last but not the least, this is the first time that a woman is selected to serve as editor-in-chief for any GI journal. Dr. Kanwal has made history and she also deserves this appointment.
