Yuan Liu, MD, PhD, joined the Department of Chemistry and Biochemistry at Florida International University in 2010 as a faculty member. Her research interests focus on understanding the molecular mechanisms by which DNA damage and repair modulates genome and epigenome stability and their roles in development, prevention, and treatment of human cancer and neurodegenerative diseases such as Huntingtonâs disease and Friedreichâs ataxia, among others. Additionally, Dr. Liu is exploring DNA repair as a biomarker for diagnosis, treatment and prognosis of cancer and human neurodegeneration, and drug discoveries of DNA repair inhibitors as treatments of human diseases.
