个人简介

Ph.D., University of Wisconsin—Madison, 2009 Our lab engineers proteins and peptides to specifically recognize proteins and cells with the goal of enhancing the understanding of fungal disease and developing tools for fungal disease diagnosis and antifungal drug design. Fungal infections are a serious medical concern for patients with compromised immune systems, such as patients undergoing chemotherapy or patients with HIV or AIDS. A limited number of antifungal drugs are available to treat fungal disease, and the use of these drugs can be limited by resistance to the drugs or by toxicity of the drugs. We use protein engineering strategies, including both rational design and directed evolution, to design protein and peptides tools that allow us to evaluate new antifungal drug targets and engineer increased specificity of antifungal agents. We are also interested in developing diagnostic tools to improve the detection and identification of fungal pathogens.
