Research:
Antimicrobial resistance is a threat to public health. The Boll laboratory is focused on understanding a variety of antimicrobial resistance mechanisms. We also aim to develop new therapeutics to combat multidrug resistant bacteria. We are particularly interested in Gram-negative bacteria that thrive in hospitals and other clinical settings.
A few of the projects that we are focused on the laboratory are:
- How Gram-negative bacteria chemically modify the cell surface to develop resistance to clinically relevant antimicrobials.
- Understanding the signaling pathways that regulate chemical addition to the bacterial cell surface.
- Drug discovery to develop compounds to combat drug resistant bacteria.
