Personal profile

Research interests

  1. The role of endogenous estradiol metabolites in preeclamsia, ischemia reperfusion injury and Alzheimer’s disease. (Gender differences in diseases). The projects aim at understanding how estradiol metabolites offer protection in these diseases/conditions thus leading to new therapeutic avenues. Currently the role of estradiol metabolites in Alzheimer’s disease is actively being investigated
  2. Investigating dietary supplements/natural compounds as inhibitors of nicotine metabolizing enzyme P450 2A6 as a means of reducing smoking by inhibiting nicotine metabolism. (Currently active).
  3. Peritoneal adhesions, cause and methods of resolving them. The project aims at identifying mechanisms and therapeutic methods for resolving adhesions, a post-operative problem resulting in pain and usually requiring second surgical operation. Adhesions result when tissues adhere together after surgery as a result of injury.
  4. The role of MIF-Glucocorticoid axis in the pathogenesis atherosclerosis and other inflammatory cardiovascular diseases. The project aims at understanding how inflammation can be resolved in these chronic inflammatory conditions by modulating endogenous regulatory switches such as MIF-glucocordicoids, thus leading to inflammation resolution and therapy. Special interest also for inflammation in cancer.
