RESEARCH INTERESTS:  Innate immune cells that provide protection against infection

COURSES TAUGHT:  MB 416/516 Medical Immunology; MB 417/517 Medical Immunology Laboratory; MB 699 Special Topics in Immunology

 

Research:

I have worked mainly on projects focused on the role of innate immune cells in providing protection against infections.  My areas of expertise are on macrophage cells and their functions including phagocytosis and how they sense pathogens by Toll-like receptors.  My current work is in collaboration with Dr. Fritz Gombart studying anti-microbial peptides produced by immune system cells.  The particular antimicrobial peptide we focus on is cathelicidin which is unique in that it is regulated by Vitamin D.  We use both human cells and mouse models to understand the roles of Vitamin D and cathelicidin in immune system functions.
