The Microbiome and IBD

Watch the video to learn about the relationship between the microbiome and IBD, including how gut bacteria respond to changes in their environment such as treatment and diet, and the impact that this has on people living with Crohn's and colitis.

Dr. Tropini is a recipient of a 2019 Crohn's and Colitis Canada Grant-in-Aid Research Grant. Her team is developing algorithims to predict disease state and drug effectiveness, as well as microbiota therapies for IBD.



Dr. Carolina Tropini (Ph.D., Eng.L.), is an Assistant Professor at The University of British Columbia in the School of Biomedical Engineering and Department of Microbiology and Immunology.

Dr. Tropini’s interests are in medicine, microbial biophysics and engineering. Working in the field of the gut microbiota, she is applying novel tools to better understand the stability of microbial communities and their response to IBD. She is building a comprehensive understanding of the complex interactions between microbes and their hosts.

Dr. Tropini is also interested in teaching and outreach, particularly with the goal of building a common language between physicists and engineers, biologists and clinicians. She was a recipient of a 2019 Crohn's and Colitis Canada Grant-in-Aid Research Grant
