Research in the Aron laboratory focuses on the chemical biology of metals and metal-binding molecules in microbial systems. We develop and apply mass spectrometry-based methods to discover and characterize new metal-binding molecules that mediate microbe-microbe and host-microbe interactions. Our research touches on the three main questions with regards to metal binding molecules (1) what are they? (2) what do they do? (3) how do they affect us?
