Research Interests:
Dr. Liu's research interests are multidisciplinary. He is engaged in medicinal and polymer chemistry for the development of novel biomaterials that will serve to improve clinical outcomes for a range of inflammatory, degenerative, cancerous and infectious disorders involving multiple organ systems.  His most recent works and an area of significant international interest and impact rest in the development of long acting cell targeted antiretroviral therapies. His highly innovative research has led to the development of innovative sustained release antiviral strategies for HIV disease treatments.  These have been developed from chemical approaches to testing of drug biodistribution and antiretroviral responses in humanized mouse models of human disease.  Prevention of HIV transmission and acquisition of new infections are other applications pursued. The research has gained international attention as adherence to dosing regimens is one of the major limiting factors for antiretroviral drug effectiveness. These studies have been sped through his comprehensive knowledge of bioengineering, for developing novel biomaterials, in utilizing cell targeted drug delivery systems (DDS), and most recently in the realization that through low-molecular-weight prodrugs enhancements can be realized in pharmacokinetics.  He has also developed theranostic application for HIV and a broader range of infectious and degenerative disorders. His current works are focused on using these technologies towards HIV eradication.

Specific areas include for HIV disease and beyond (neurodegenerative disorders, cancer, inflammatory and orofacial diseases)
•    Nanoformulated antiretroviral therapeutics (NanoART)
•    Liposomes, micelles and solid lipid nanoparticles (SLN)
•    Ultrasmall superparamagnetic iron oxide (USPIO) nanoparticles for theranostic application
•    Polymer therapeutics
•    Novel prodrug design
