Alberto completed his PhD in microbiology at the University of Leon, Spain. The central aim of Alberto’s research is to investigate the impact of the gut microbiota alterations in celiac disease. At Verdu lab, he identified opportunistic pathogens in the small intestine of patients with celiac disease that, through elastase production, increase the immunogenicity of gluten. From July 2019, Alberto will join the faculty of the Farncombe Institute as Assistant Professor.

Heather Galipeau, PhD
Heather obtained a PhD degree from McMaster University in 2015 and currently holds a position as Research Associate. Her research focusses on the role of commensal bacteria in modulating gluten-induced immuno-pathology. Work performed during her PhD studies showed that the small intestinal microbial background influences the degree of immuno-pathology triggered by dietary antigens such as gluten. Heather also investigated potential new therapies to support a gluten-free diet. She discovered that elafin expression in the intestinal epithelium of celiac patients was lower than in patients one year after the gluten free diet and than in non-celiac people. Her team found that elafin could delay the rate of deamidadion by human tissue transglutaminase 2 (TG2) of the immunogenic gluten peptide 33-mer.

Miriam Bermudez Brito, PhD
Miriam obtained her PhD in microbiology at Complutense Madrid, Spain. At Verdu lab, she investigated the role of bacterial proteolytic activity in inflammatory bowel disorders. She isolated and characterized the bacterial proteolytic activity isolated from patients with ulcerative colitis, and used these communities to colonize germ-free mice. Miriam is now a group leader and research scientist at a major Pharmaceutical company in The Netherlands.
- MITACS Elevate PDF award
Jane Natividad, PhD
Jane studied the cross-talk between gut bacteria and host tissues. Using gnotobiotic mice she demonstrated that although intracellular bacterial sensors are important in the regulation of colonic paracellular permeability and susceptibility to colitis, changing the intestinal microbiota composition results in normalization of colitis susceptibility. Jane identified that specific components of the microbiota differentially regulate RegIII expression. Her studies revealed that colonization of germ-free mice with a microbiota low in the core family of Firmicutes derived from patients with severe and active ulcerative colitis, promoted a molecular Th17 pro-inflammatory signature that increases colitis severity. After successful post-doctoral training at INRA, Paris (France) funded by a CIHR fellowship, Jane obtained a Research Scientist position at Nestle Research Center (Switzerland).
