Dr. Allison Predecki
Associate Professor of Organic Chemistry
My research centers around two areas, bioorganic chemistry and synthetic methodology. Bioorganic chemistry links the two disciplines of organic chemistry and biology. Whereas synthetic methodology focuses on the development of new methods for the synthesis of organic molecules.
My first project involves the identification of organic molecules that are capable of inducing damage to DNA when exposed to ultraviolet light. My research group synthesizes different aryl sulfoxides, tests their ability to cleave DNA and determines their binding affinity towards DNA.
Cycloaddition reactions are commonly used to construct rings in organic synthesis. For example, alkenes can combine with 1,3-dipoles to form five-membered rings. Students in my research group also work on a project where they study the feasibility of a new cycloaddition reaction using carbenes and 1,3-dipoles to form four-membered rings.
