Research Emphasis: Inflammation is an organism’s protective mechanism to cope with the altered cellular environment, trauma, injury and/or infection. While acute inflammation (which is resolved quickly) has many beneficial effects, chronic inflammation is a serious problem and leads to many pathophysiological conditions. Major focus of my research has been the elucidation of the molecular events associated with amyloidosis, arthritis, atherosclerosis and cancer, all of which are results of abnormal gene expression during persistent and chronic inflammation.
