Research interests

Postdoctoral Fellow Heather Shearer is investigating the mechanisms underlying S. pneumoniae resistance to oxidants.

She recently completed her PhD project on the sensitivity of S. pneumoniae to oxidative stress, and how we can improve the killing of these pathogenic bacteria by our immune systems.
