Adult Stem Cell Niches & Tumor Microenvironment
We are working to unravel the biological complexity of tissue homeostasis since its disintegration underlies cancer and disease. Control over structural scaffolds, stem & progenitor cell populations, and instructive signals is essential for healthy aging of tissues. We excel at developing cutting-edge systems including genetically engineered mouse models and primary human cell mutagenesis platforms. We are known for our discoveries in proteolytic regulation of cell signalling, adult stem cell dynamics, and new cancer driver genes that govern tumorigenesis. We are translating our findings to benefit cancer therapy, prevention and cure.

Foram and Bowen presented at the first annual Medical BioPhysics Symposium, a full-day student-led conference. Due to pandemic restrictions, the event was hosted virtually. Despite the distance, the Symposium was successful in bringing MBP faculty and students together to celebrate the accomplishments of our diverse department. See article.
At the Parliamentary Health Research Caucus event called “Cancer Gone: The Research and Innovation that Thinks it Can,” Rama presented the Princess Margaret initiative called ‘molecular cancer prevention (MCP)’ that she started alongside Dr. Hal Berman and Dr. Stephanie Lheureux. This event explores the advances in cancer research and introduces Parliamentarians to Canada’s best and brightest researchers and research teams working in the field.
Congrats Foram on being awarded CGS-M this year! The CGS-M program provides financial support to high-calibre scholars who are engaged in eligible master’s or, in some cases, doctoral programs in Canada.
Happy International Women's Day! Celebrating women in science.
Barbara's preprint is now on bioRxiv.
