Research Interests

The Weiser Lab has several interests: (1) Understanding how protein-protein interactions influence protein activity; (2) Discovering small molecules that can be used therapeutically or to explore protein function; (3) Developing statistical methods to understand non-canonical dose-response relationships.

Our projects examine DNA repair proteins, sirtuin deacylases, and various macromolecular complexes. We use traditional biochemistry methods along with computational, structural, and statistical modeling.

Keywords: replication protein A (RPA), uracil DNA glycosylase (UNG2), sirtuin isoform 2 (SIRT2), proliferating cell nuclear antigen (PCNA), propofol, fluorescence, hormesis, 1-aminoanthracene, dose-response

We welcome all opportunities to collaborate with other research groups to share our technical and material resources!
