Contact Information:

Research in the Winkle lab focuses on the interactions of small molecules such as antiparasitic agents, carcinogens and anticancer drugs, with DNA and on the interactions of proteins with DNA. We are interested in how these species alter the structure and functioning of DNA and in how altering the structure of the bound molecule affects such alterations. All research in the lab involves undergraduates as illustrated by the papers/presentations listed below.
