A long term goal of my laboratory is to understand mechanisms through which inflammation contributes to diseases like atherosclerosis and asthma. Several major research programs are currently under investigation. One research program focuses on the role of myeloperoxidase, a leukocyte heme protein, in promoting oxidant stress in vivo, and its participation in cardiovascular diseases. A second area focuses on HDL structure and function. A final area of research interest focuses on the role of intestinal microbiota in cardiometabolic disease.
All research projects rely heavily on chemical and analytical methods to identify specific reactions/products, their mechanisms of formation, and their use as probes to elaborate pathways responsible for disease. Research efforts in each program span from bench-to-bedside, including basic/genetic, cellular, animal model, andhuman clinicalinvestigations.
In other words ...
A long term goal of my laboratory is to understand the ways in which our immune system contributes to diseases like heart disease and asthma. I have several major areas of focus. One centers on the role of myeloperoxidase, a protein found in white blood cells that plays an important role in fighting infections, but which we have discovered also participates in development of heart diseases. A second area focuses on the role of microbes in our intestines (called gut flora) in heart disease. Another area focuses on the HDL particle (carrier of good cholesterol in the blood).
