His main project involves researching the mechanisms through which B. thetaiotaomicron and other Bacteroides exert catabolite repression on the various diet and host polysaccharides they encounter in the gut. https://images.squarespace-cdn.com/content/v1/5a2feb0b8fd4d2c11bbdd4d1/1535575263274-K7XKKNWK0YBFK0Y8AAI1/Gabriel+Pereira%281%29.jpg Lab Members - Gabriel Vasconcelos Pereira, PhD Research Investigator. Dr. Vasconcelos Pereira received his PhD in July 2018 working with Dr. Isaac Cann at the University of Illinois, Urbana-Champaign. His research interests in the Martens Lab are focused on the timing and biochemical composition of dietary fibers that restore beneficial gut bacteria and suppress the activity of mucus-degrading bacteria. He is leading a project to investigate the dietary and gut microbial contributions to inflammation development in mice lacking the cytokine IL-10, which has been associated with human neonatal IBD. https://images.squarespace-cdn.com/content/v1/5a2feb0b8fd4d2c11bbdd4d1/1535576325495-3E357RFP624GLWTCDOY2/crop_IMG_6919.jpeg Lab Members - Nathan T. Porter, PhD Dr. Porter received his PhD from the lab in Fall 2017. He used molecular genetic approaches to study how one prominent human intestinal bacterium, Bacteroides thetaiotaomicron, interacts with its host and adapts to the ever-changing environment of the intestine. Particularly, he investigated bacterial polysaccharide capsule biosynthesis and the ways in which production of variable surface capsules mediates interactions with the host immune system and bacteriophage. Nathan is currently doing postdoctoral research with Dr. Johan Larsbrink at Chalmers University if Gothenburg, Sweden. https://images.squarespace-cdn.com/content/v1/5a2feb0b8fd4d2c11bbdd4d1/1514518833314-C8FUYMATJXXY5NTH3895/eric_martens-250x250.jpg Lab Members - Eric C. Martens, PhD Dr. Martens received his PhD in 2005 from the University of Wisconsin-Madison, working with Heidi Goodrich-Blair, PhD on the biology of the entomopathogenic nematode, Steinernema carpocapsae, and its bacterial symbiont, Xenorhabdus nematophila. He then trained with Jeffrey I. Gordon, MD at Washington University School of Medicine, investigating the physiology of beneficial human gut bacteria, especially members of the Bacteroidetes and their interactions with complex carbohydrates. His current research interests include investigating the roles of gut bacteria in human digestive physiology, the gut microbiome in inflammatory bowel disease and colorectal cancer, genetic exchange between environmental and gut bacteria and mechanism through which gut bacteria break down dietary fiber polysaccharides and mucin glycoproteins. https://images.squarespace-cdn.com/content/v1/5a2feb0b8fd4d2c11bbdd4d1/1579276317840-DCHNTLPD7JY31YK6FOE9/Fuentes+2.jpeg Lab Members - Jaime Fuentes, MS Jaime earned his MS at Sacramento State. His projects in the Martens Lab are focused on the role of Bacteroides thetaiotaomicron phase-variable surface proteins (S-layer proteins and nutrient receptors) in evading or promoting infection by bacterial viruses (bacteriophages). Jaime is a Rackham Merit Fellow and is a trainee on the NIH-sponsored Genetics Training Program training grant. https://www.ericmartenslab.org/people-projects daily 0.75 2017-12-13 https://images.squarespace-cdn.com/content/v1/52a74d9ae4b0253945d2aee9/1390928870858-4D9B6T9WGP8017NSS9W3/topography.jpg Copy of People & projects https://www.ericmartenslab.org/research-projects daily 0.75 2018-10-02 https://images.squarespace-cdn.com/content/v1/5a2feb0b8fd4d2c11bbdd4d1/1514513010910-VMZ555WCNSC23TJ5OYLO/capsule.jpg Research Projects https://www.ericmartenslab.org/project-1 daily 0.75 2018-07-21 https://www.ericmartenslab.org/dietmicrobiome daily 0.75 2018-08-29 https://www.ericmartenslab.org/capsules-and-phage daily 0.75 2018-07-21 https://www.ericmartenslab.org/global-regulation daily 0.75 2018-10-02 https://www.ericmartenslab.org/gene-transfer daily 0.75 2018-07-21 https://www.ericmartenslab.org/enzymatic-degradation-of-intestinal-mucus daily 0.75 2018-07-21 https://www.ericmartenslab.org/new-page-2 daily 0.75 2018-08-30 https://images.squarespace-cdn.com/content/v1/5a2feb0b8fd4d2c11bbdd4d1/1535638735851-PG1ECR8HK65HQ7THLQEO/GroUM+logo.png GroUM! list and metrics https://www.ericmartenslab.org/regulation daily 0.75 2018-10-02 https://www.ericmartenslab.org/salyers daily 0.75 2018-12-26 https://www.ericmartenslab.org/home-alt-bedford daily 0.75 2025-05-12 https://images.squarespace-cdn.com/content/v1/52a74d9ae4b0253945d2aee9/1390500612440-PGQSIY8KL9F7T5VIXQLO/chambers-2.jpg Home Alt A better world Starts with a choice Contact Us https://images.squarespace-cdn.com/content/v1/52a74d9ae4b0253945d2aee9/1390500503574-5BAPXZO9U06UV61P49UO/chambers1.jpg Home Alt Sustainability Starts with you Join Us https://images.squarespace-cdn.com/content/v1/52a74d9ae4b0253945d2aee9/1390500933384-LII4SRIPHFYOUFX0UCXC/chambers-4.jpg Home Alt A better world Starts with a choice Join Us https://images.squarespace-cdn.com/content/v1/52a74d9ae4b0253945d2aee9/1390504287124-HQ8GNX1JCE22V047MSQ9/chambers-8.jpg Home Alt Preserve Nature Join Us
