Research in the Maloney lab focuses on the small organic molecules (natural products) produced by some organisms to facilitate their interactions with other organisms. In one project, we are growing plant-associated fungi on a variety of different media and characterizing the antibiotic natural products that are selectively produced in some media but not others. In another project, we are exploring the use of natural product profiles to complement molecular (DNA) phylogenetic analyses in studies of the evolutionary relationships among soft corals.
