X. Margaret Liu, PhD, is a professor of chemical and biomolecular engineering at The Ohio State University. Her research focuses on developing targeted therapies for cancer, particularly through the use of engineered nanoparticles and gene delivery systems. Liu’s work emphasizes the design of precise therapeutic tools that enhance the selective targeting of cancer cells while minimizing damage to healthy tissues. She has contributed significantly to advancing cancer treatments, including the development of light-activated gene therapies aimed at mitochondrial disruption.
