Dr. Robert Hancock is a Professor of Microbiology and Immunology, UBC, and a Canada Research Chair in Health and Genomics. Bob has published more than 660 papers and reviews, and has 50 patents awarded. The fundamental interest of Dr. Hancock and his laboratory is in designing new therapeutic strategies to treat infections in the light of increasing antibiotic resistance coupled with a dearth of new antibiotic discovery. Recently his team and their collaborators at the University of British Columbia have created an innovative technique for studying how chlamydia interacts with the human immune system. The researchers used a combination of gene editing and stem cell technologies to make the model. The results, reported in Nature Communications, identify novel drug targets for the sexually transmitted disease.
