Jonathon Briggs completed his undergraduate degree in Medical Microbiology and Immunology at Newcastle University before undertaking his PhD studies in the lab of Professor Harry Gilbert. His PhD project focused on utilization of various glycan substrates encountered by the prominent gut microbes Bacteroides thetaiotaomicron and Bacteroides ovatus.

Jonathon contributed to the characterization of the B. ovatus xylan utilization system [1], the B. thetaiotaomicron galactan, arabinan, rhamnogalacturonan I [2] and II utilization systems [3]. In the process of characterizing the arabinan and galactan utilization systems he identified the founding members of Glycoside Hydrolase families GH146 and GH147 [3].

Jonathon has recently joined the lab of Harry Brumer at the University of British Columbia.
