Carolyn Thomson, PhD

Postdoctoral Fellow

Dr. Thomson is a senior postdoc in the department of Physiology & Pharmacology and the Snyder Institute of Chronic Diseases at the University of Calgary. Her current research is focused on establishing how maternal colonization impacts immune and metabolomic profiles in the offspring, from early life into adulthood, particularly in the context of autoimmune disease development. Dr. Thomson began her academic career at the University of Glasgow, where she completed a BSc and PhD in Immunology. Her first postdoc position, also at the University of Glasgow, brought her into the field of mucosal immunology. Here she identified and characterized a novel population of intestinal fibroblasts. She is not a fan of work without play. She is an avid gin enthusiast and spends her spare time camping, climbing, and hiking in summer, or shredding the slopes in the harsh Canadian winter.

Aline Ignacio, PhD

Postdoctoral Fellow

Dr. Ignacio is a recipient of an Eyes High Postdoctoral Fellowship. She explores the crosstalk between the intestinal microbiota and mucosal immune cells under homeostatic conditions, which may provide insights into mechanisms responsible for dysregulated immune responses during disease. Dr. Ignacio also studies the early events in microbial-mediated immune education. She obtained her MSc from the University of São Paulo, Brazil, specializing in Microbiology, and her PhD from University of São Paulo, Brazil, specializing in Immunology.

Marcela Davoli Ferreira, PhD

Postdoctoral Fellow

Dr. Ferreira is a recipient of a Beverly Philipps Postdoctoral Fellowship and a Cumming School of Medicine PDF Fellowship. Her research focuses on defining how host-microbiota interactions can promote or prevent autism spectrum disease (ASD). She uses a diverse set of immunological approaches, next-generation sequencing, imaging screening, microbiota cultivation, and gnotobiotic models to further define the molecular mechanisms by which these specific commensals bacteria can influence ASD development. This research aims to develop novel therapeutic interventions for ASD based on the modulation of gut bacteria. Marcela obtained her MSc in Immunology at the University of São Paulo (Brazil). She was awarded a PhD in Immunology from the University of São Paulo where she studied the role of regulatory T cells in the development and maintenance of neuropathic pain after peripheral nerve damage.

Kirsty Brown, MSc

PhD Student

Kirsty has a general interest in how bacteria regulate host physiology, and enjoys applying wet lab techniques and bioinformatics to explore these interests. Her current project investigates how bacterial colonization impacts stromal cell populations in the intestine with a focus on bacteria-induced metabolites. Prior to entering the PhD program at the University of Calgary, Kirsty completed a Master’s degree at the University of British Columbia and worked for a few years at Agriculture and Agri-Food Canada. She also enjoys outdoor activities including hiking, snowboarding, and backcountry camping.

Amanda Zucoloto, MSc

PhD Student

Amanda is a recipient of the Beverley Phillips Scholarship, the Cumming School of Medicine Scholarship, and the Frederick Banting & Charles Best Canada Graduate Scholarship. Amanda aims to understand the crosstalk between the gut microbiota and the intravascular immunity using intravital microscopy and gnotobiotic models. She obtained her MSc in Experimental Pathology from the Universidade Estadual de Londrina in Londrina, Brazil. During her undergraduate studies, she attended the University of Calgary as a visiting student. Here, Amanda was introduced to intravital microscopy, a cutting-edge technique she aspired to incorporate in her graduate studies. Amanda joined the McCoy and McDonald labs as a PhD student in 2019. In her spare time, Amanda enjoys running, hiking, reading, and camping.

Madeleine Wyss, MSc

PhD Student

Increasing evidence suggests that exposure to a diverse set of ‘friendly’ microbes in early life is important, to prevent the development of allergies. The aim of Madeleine's project is to determine the minimal diversity of microbiota required that limits the induction of hygiene-mediated IgE and protects against immune dysregulation. Furthermore, she is particularly interested in the dynamics of early life microbial colonization and its impacts on immune development. Madeleine completed her BSc at the University of Guelph where she specialized in Microbiology. She then moved to Singapore, where she completed her MSc at the University of Singapore in the Department of Infectious Diseases, Vaccinology and Drug Discovery.

Shannon Pyke, BSc

MSc Student

Shannon studies the dynamic function of specific bacterial species in the gut and how they may play a role in anti-microbial resistance. Shannon is from Calgary and completed a Bachelor of Science in Microbiology at the University of Victoria. After graduating, she worked in the biotechnology industry in Vancouver before moving back to Calgary to pursue a Master's degree. In her spare time, she swims competitively and enjoys running, hiking, skiing, and reading.

Sonia Czyz, BSc

MSc Student

Sonia is a Master's student specializing in Microbiology and Infectious Diseases. She obtained her BSc in the Biological Sciences here at the University of Calgary. Having had the opportunity to investigate advanced topics in immunology during her undergraduate studies, she became fascinated with the interplay between the microbiota and the immune system. Her project is focused on investigating how the maternal microbiota shapes the newborn’s developing immune system during early-life. Her research aims to better understand how we can target the maternal microbiome to promote healthy immune development in offspring. Outside of the lab, Sonia enjoys watercolour painting, golf, soccer, and taking her little Yorkshire terrier on long walks.

Past Members

Lukas Mager, PhD

Postdoctoral Fellow

Cancer is one of the most common causes of death in Western countries. Surgery, chemotherapy, radiation, or a combination thereof are the standard tools for the treatment of cancer. More recently, the intestinal microbiota has been shown to modulate cancer development and even affect the efficacy of cancer therapies. Dr. Mager's aim was to better understand the interaction between the host organism and the microbiota in the context of cancer development and therapy. Besides science, he deeply enjoys being out in nature. One of his favourite hobbies is hiking in mountains. He also enjoys reading and is a fan of strategy games.

Jenine Roslyn Yee, MSc

MSc Student

Jenine was a MSc student in gastrointestinal sciences studying the impact of the gut microbiota on autism spectrum disorder (ASD). She received her nursing degree from University of Calgary before following her unanswered questions about gut health and its resident bacteria. When she isn’t culturing bacteria in lab, she spends time learning piano and cultivating the best tiny potatoes in clay soil.

Noah Cooke, MSc

MSc Student

Noah's MSc project in Gastrointestinal Sciences investigated the potential link between major depressive disorders (MDD) and the microbiome (co-supervised by Dr. Valerie Taylor). Through gut microbial analysis combined with gnotobiotic models, he aimed to further understand the mechanisms by which the gut microbes can impact MDD. Noah is a competitive cross-country skier and runner, and loves the mountains. He also loves politics and public policy.
