THE LAB

OUR LAB

Dr. Brian K. Coombes’ laboratory is in the Department of Biochemistry and Biomedical Sciences and the Michael G. DeGroote Institute for Infectious Disease Research at McMaster University. We are affiliated with the Michael G. DeGroote School of Medicine, a full-service research and teaching hospital located on the McMaster University campus. The McMaster campus is situated on 300 acres of property nestled in the Niagara escarpment. Hamilton is 45 minutes from Toronto.

The Center for Microbial Chemical Biology is a full-service high-throughput screening facility.
