My research focuses on investigating the mechanisms of action of newly designed antimicrobial peptides and peptidomimetics.  These new antimicrobials are able to kill many different types of microbes including bacteria, fungi, and viruses. I am particularly interested in how these new antimicrobials prevent microbes from colonizing surfaces. My research has applications for preventing the transmission of disease and reducing the incidence of hospital-acquired infections.
