Sara Andres

Sara Andres is an Associate Professor in the Department of Biochemistry & Biomedical Sciences at McMaster University. Her research focuses on DNA repair mechanisms, bacterial translesion synthesis, and protein-DNA interactions. She has contributed to studies on DNA repair in pathogens like Mycobacterium tuberculosis and the role of proteins such as LigD and Ctp1 in DNA repair processes.

Her teaching includes courses like 'Structural Determination and Analysis of Macromolecules' (BIOCHEM 3Z03) and advanced biomedical sciences topics. She has published over 30 articles in journals such as *Proceedings of the National Academy of Sciences*, *Nucleic Acids Research*, and *Nature Communications*.

Key research areas include poly ADP-ribose signaling in Huntington disease, SUMOylation in cancer stem cells, and structural studies of DNA repair proteins. Her work bridges molecular mechanisms in bacteria and human diseases, with a focus on translational applications in therapeutics and diagnostics.
