Research Interests

Dr. Liu’s research is multidisciplinary and mainly lies in the areas of computational and mathematical biology, and computational fluid dynamics. One of his current research projects is focused on the numerical simulation and mathematical modeling of cancer stem cells and cell signaling pathways, which play vital roles in the development of a variety of life-threatening or chronic diseases, such as cancer, autoimmunity and diabetes. His work has been partially supported by NSF Grants, South Carolina EPSCoR GEAR grants, and the USC ASPIRE I grant. Dr. Liu has been invited to serve as NSF panel, referee for more than 25 professional journals, and give more than 90 research talks, department seminars or colloquium at various professional conferences, universities, and national labs.
