Current Members of the Geuking Lab

Dr. Markus Geuking, PhD

Dr. Markus Geuking is an Assistant Professor at the University of Calgary's Cumming School of Medicine. He is a member of the Department of Microbiology, Immunology and Infectious Diseases as well as of the Snyder Institute for Chronic Diseases. Dr. Geuking obtained his PhD in Immunology from the Federal Institute of Technology in Zurich (Switzerland) where he worked in the lab of Nobel Prize Laureate Prof. Rolf Zinkernagel. He started to work on host-microbial immune interactions using germ-free and gnotobiotic models during his postdoctoral studies at McMaster University (Hamilton, Canada). He then continued this work as a research associate at the University of Bern (Switzerland) before joining the University of Calgary in 2016.

Markus Geuking has over 30 peer-reviewed publications in journals such as Science and Immunity. He received the AbbVie IBD Grant (2015), Lutz Zwillenberg Award (2012), and Swiss National Science Foundation Ambizione Grant (2010).

Mike Dicay, Lab Manager

Michael is managing the McCoy and Geuking labs. He is investigating the role of the microbiome in many different disease states. He performs experiments and helps graduate students, Post-docs and staff with their projects while making sure the labs run smoothly. Michael has over 25 years of research experience with the University of Calgary. Starting in Neuroscience investigating stem cell neuroplasticity for several years working with Dr. Sam Weiss, Michael then worked in the field of inflammation in the gastrointestinal tract with Dr. John Wallace and Dr. Wally MacNaughton.

Dr. Regula Burkhard, Postdoc

About Regula...

Dr. Roopa Hebbandi Nanjundappa, Postdoc

Roopa’s research focuses on understanding how the intestinal microbiota modulates CD4+ T-cell responses in an antigen-specific manner. Roopa completed her PhD in immunology under the supervision of Dr. Pere Santamaria from the U of Calgary in April 2019. Then she finished six months of clinical research training to understand the medical management of complex disease, hepatitis B infection under the supervision of Dr. Carla Coffin. During her PhD, she discovered how a gut microbial molecular mimic to pancreatic beta-cell auto-antigen can protect the host from inflammatory bowel disease. Her PhD work raised a strong interest and curiosity in her towards host and microbiota interaction.

Kirsten Wilson, MSc student

Kirsten investigates how bacteria-specific T helper cell subsets impact on humoral antibody responses with translational implications in immune mediated disorders such as Inflammatory Bowel Disease and vaccine development. She completed her BScH at Queen's University with a specialization in molecular biology and has presented her work at international conferences in Canada and the United States. Her laboratory specializations include DNA cloning, DNA isolation, PCR, production of proteins, protein assays, gene crosses, and biochemical and immunological analysis of proteins. In her free time, she enjoys anything involving the mountains including rock climbing, ice climbing and skiing.

Sharon Dong, MsC student

Sharon investigates the impact of intestinal microbial colonization during pregnancy on Type 1 Diabetes development in the offspring. To do so, she is engineering auxotrophic bacterial species capable of transiently colonizing germ free mice mothers. This way, she can study the effect of microbial metabolite transfer on the development of T1D in the offspring mice. When she is not in the lab, Sharon enjoys activities with her friends, she likes to stay active, go on hike, dance and meet new people.

Visiting Student

Gabriela Quiroz-Olguin, PhD Student

Gabriela is a PhD student from Mexico. She is visiting the Geuking and McCoy's lab for 6 months (10/19-03/20), to learn microbiome sequencing and IgA-SEQ. While working as a certified dietitian in Mexico City, Gabriela completed a Master’s Degree in Education at Universidad Tecnológica de Mexico. She then started a PhD in Clinical Nutrition at the Universidad Anahuac in Mexico City working on the effect of fasting and enteral stimulation on the IgA concentration in saliva of patients pursuing a stomal reversal. Gabriela is a great singer and guitar player. She like long distant running, completed several half marathons, and is looking forward to visit the vibrant Rocky Mountains.
