Members of the MacNaughton Lab

Dr. Wallace MacNaughton

Wally obtained his BSc (1984) and MSc (1986) in Biology from Queen’s University in Kingston, Ontario. After a brief stint as a lab technician at McMaster University and Queen’s, he completed his PhD in Physiology at Queen’s in 1989, under the supervision of Dr. John Wallace. It was in Dr. Wallace’s lab that he developed his interest in the mediators of mucosal healing in inflammatory diseases of the gut. He then did post-doctoral fellowships at University of Calgary, under Dr. Grant Gall, and at the University of Ottawa, under Drs. Tony Krantis and Kent Harding. In 1991, Wally joined the Department of National Defence (Canada) as a Defence Scientist in the Radiation Biology Group, studying the effects of ionizing radiation on intestinal epithelial function, and had adjunct appointments in the Departments of Physiology and Medicine at the University of Ottawa. He joined the Faculty of Medicine at the University of Calgary in 1996, and is currently Professor and Head of the Department of Physiology and Pharmacology in the Cumming School of Medicine. Wally’s current research interests are in intestinal epithelial biology in health and disease, particularly the factors that regulate epithelial restitution and mucosal healing in the Inflammatory Bowel Diseases, Crohn’s disease and ulcerative colitis. His lab has been continuously funded by the Canadian Institutes of Health Research and Crohn’s and Colitis Canada, with additional support from the Natural Sciences and Engineering Research Council and the University of Calgary.

Dr. Cristiane Baggio

Cris joined the MacNaughton lab as a University of Calgary Eyes High post-doctoral fellow in 2015, and is currently a senior Research Associate and lab manager. She obtained her BSc in Pharmacy (1996-2001), MSc in Pharmacology (2002-2004) and PhD in Pharmacology (2006-2010) at Federal University of Parana (UFPR), Brazil. Before coming to Calgary, Cris held the positions of Research Associate (2010-2012) and first Post-doc (2012-2015) also at UFPR. Her research interests include the role of intestinal epithelial barrier in health and in Inflammatory Bowel Disease (IBD), and the effect of polysaccharides isolated from natural products on epithelial barrier function.

Dr. Marilyn Gordon

Marilyn completed her BSc (Biological Sciences) in 2007 and her PhD (Medical Sciences) in 2015, both from the University of Alberta, and was a post-doctoral fellow in the MacNaughton lab from 2015 to August 2018. Between 2007 and 2011, Marilyn worked as a Research Associate at Global IQ Inc and the University of Alberta, coordinating and running several clinical and longitudinal studies in arthritis medications, diabetes management, childhood metabolic diseases, and inflammatory bowel diseases, exploring new diagnostic and therapeutic techniques, as well as investigating disease development and progression. During her Doctoral studies, Marilyn studied the role of tumor-suppressing proteins in regulating intestinal inflammation, which led to her current research interest in how chronic inflammation disrupts epithelial tissue homeostasis and cell signaling to promote the development of cancerous lesions. In September 2018, Marilyn took on a new role as a research associate and Technical Director of the Human Tissue Research Platform run by the MacNaughton and Hirota labs.

Dr. Jean-Baptiste Cavin

Jean-Baptiste obtained a bachelor's degree in cellular biology and physiology from the University of Burgundy in 2011 and then moved to Paris where he obtained a Master’s degree in nutrition and health from the Université Pierre et Marie Curie in 2013, and a PhD in gastroenterology and physiology from the Université Paris Diderot in 2016. During his doctoral thesis in the lab of Dr. André Bado, under the supervision of Dr. Maude Le Gall, Jean-Baptiste studied how the gastrointestinal tract adapts to different diets and bariatric surgeries, and the consequences of this adaption on metabolism. His thesis work has been recognized by several awards, including the Claude Rozé Prize in 2016, best thesis award from the European Association for the Study of Obesity, and the young researcher prize of the Bettencourt Schueller Foundation in 2017. Since joining the University of Calgary in October 2016, Jean-Baptiste has received postdoctoral fellowships from the Human Frontier Science Program, Alberta Innovates, the Canadian Association of Gastroenterology and the Killam Foundation. Working in the labs of Drs. Keith Sharkey and Wally MacNaughton, Jean-Baptiste is working to understand the role of the enteric nervous system in how nutrients affect gastrointestinal permeability in healthy subjects and in the context of inflammatory bowel diseases.

Dr. Larissa Lucena Périco

Larissa holds a bachelor's degree in Generalist Pharmacy from Faculdades Adamantinenses Integradas, Brazil (2007-2010), a Master's degree in Biological Sciences (Pharmacology) from the Biosciences Institute, UNESP, São Paulo State University, Brazil (2012-2014), and PhD in Pharmacology and Biotechnology, also from São Paulo State University (2014-2018). Larissa joined the MacNaughton lab as a Postdoctoral Fellow in March 2019, where she is advancing our studies of protease-activated receptor (PAR)-2 as a novel effector of mucosal healing in inflammatory bowel diseases. She brings a wealth of experience to the lab, having worked with experimental models of protection and healing of peptic ulcers, diarrhea, intestinal motility, pain and inflammation in animal models, as well as molecular biology techniques. Larissa is the recipient of the Beverly Phillips Postdoc Award from the Snyder Institute for Chronic Diseases, and a postdoc award from the Cumming School of Medicine.

Dr. Bianca Crífo

Bianca holds a Bachelor's degree in Biotechnology for Health (2006-2010) and a Master's degree in Medical Biotechnology (2010-2012) from the University of Naples, Italy. She started a PhD in Translational Medicine at University College Dublin (2013-2017) where, under the supervision of Prof. Cormac Taylor, she focused her thesis on the identification of innate immune mechanisms involved in the therapeutic use of hydroxylase inhibitors in inflammatory disease models. Bianca joined the MacNaughton lab as a Postdoctoral Fellow in August 2019 and she is now advancing our studies on understanding how inflammation-associated protease milieu is important for epithelial healing and resolution of inflammation in inflammatory bowel disease models. She brings immunology and microbiology experience to the lab, having worked with experimental models of colitis, G. mellonella virulence models, as well as primary immune cells.

Elizabeth Hughes

Elizabeth has a BSc and MSc in pharmacology, both from the University of Alberta. During her career Elizabeth has worked on projects ranging from diabetes to MS to autism. Elizabeth brings to lab a wealth of experience using a variety of techniques including islet isolation, western blots, qPCR, cell culture, and animal work. Elizabeth has been working at University of Calgary since 2008 and joined the MacNaughton lab as a cell culture technician in the Human Tissue Research Platform in March 2019.

Andrew Vegso

Andrew is a MSc student born and raised in Calgary. He graduated from the Bachelor of Health Sciences at the University of Calgary in 2014, completing his honour’s undergraduate project in the MacNaughton lab. Since then, Andrew has worked in multiple health research-related positions and is currently pursuing further graduate studies. His project is focused on identifying the underlying mechanisms and signaling pathways that promote epithelial wound healing induced by proteases and their receptors. Andrew is the recipient of a Master’s Award from the Canadian Institutes of Health Research.
