PhD Candidate





Why Dal?

Research-intensive university in a great city, and the opportunity to train at the Canadian Center for Vaccinology.

What inspires me

Disulfide bonds are important for protein stability, but little is known about how they are formed in Gram-positive bacteria. By investigating disulfide bond formation in Streptococcus gordonii, a potential live vaccine vector, I hope to contribute to our understanding of protein production in this group of organisms, and to the development of novel S. gordonii based vaccines.
