Dr. Caglayan's Ph.D. work focused on investigating the temperature effect on the fidelity of bacterial DNA replication and DNA polymerase transient state kinetics. In 2013, she joined the laboratory of Dr. Samuel H. Wilson at National Institutes of Health (NIH), National Institutes of Environmental Health (NIEHS), to study the base excision DNA repair by characterizing nucleic acid-protein and protein-protein interactions and their role in coordinating the sequential enzymatic steps of the DNA repair pathway. Dr. Caglayan joined the faculty at the University of Florida in June 2018.
