  • Lyle and Sharon Bighley Endowed Chair & Professor in Pharmaceutical Sciences, Department of Pharmaceutical Sciences and Experimental Therapeutics / Division of Pharmaceutics and Translational Therapeutics

Research Narrative

Dr. Salem's research interests are primarily focused on self-assembling systems, the rational design of novel drug and gene delivery systems and on the development of sophisticated scaffolds for tissue-specific regeneration. In tissue engineering, Dr. Salem's laboratory applies microfabrication techniques to novel biomaterials to provide spatial control over tissue formation and to integrate minimally invasive scaffold delivery strategies. In drug/gene delivery, he is currently exploring the synergistic application of degradable particle technology, CpG oligonucleotides and heat shock proteins for generating sustained immunotherapeutic responses against cancer.

Research Interests
Dr. Salem's research interests are primarily focused on self-assembling systems, the rational design of novel drug and gene delivery systems and on the development of vaccines that stimulate potent antigen-specific immune responses.  Dr Salem's laboratory applies microfabrication techniques to develop novel drug and gene delivery devices and to optimize control over polymer-cell interactions. The group is currently exploring the synergistic application of polymer particle technology,  CpG oligonucleotides, adenoviruses and heat shock protein therapy for generating sustained stronger immune responses against tumors.
