Jackie Jie Li

Dr. Jackie Li is interested in nano/micro-mechanics of materials. Since coming to The City College of New York, she has conducted analytical and experimental investigations on nonlinear electromechanical coupling behavior of ferroelectrics and their composites by considering the microstructure of their systems. She has also developed a molecular mechanics based approach to study the elastic properties of carbon nanotubes. 

Dr. Li is a recipient of NSF CAREER award and a member of Frontier of Engineering, National Academy of Engineering. Her current research interests include nano-micromechanics; electro-mechanical coupling behaviors of piezo/ferroelectrics and their composites; mechanical and electrical properties of CNT and CNT composites; nanocomposites; nanoferroelectrics; self-sensing and self-health monitoring technology of structural materials and composites; energy harvesting using piezoelectrics based material systems.
