Advisees and other students can make an appointment to meet with Dr. Larsen here.
I am interested in what native bacterial communities are doing to break down and grow on antibiotics, especially synthetic antibiotics like cipro and triclosan. These drugs are constantly introduced into the environment through wastewater, and it's not surprising that bacteria, which can be incredibly versatile, would learn how to utilize such molecules as food. Most studies focus on resistance to drugs rather than metabolism of drugs, so I am interested in how some bacterial species are not only resistant but also take advantage of these new and unusual food sources. I am also interested in how often species with such abilities can be isolated (from various sources) and how many different species have learned how to do this.
