Neuropathology, Pituitary Pathology, Autopsy Pathology.


My research interests focus on two major areas: 1- Hypothalamic, pituitary and peripheral interactions in the pathogenesis of pituitary adenomas; 2 – Molecular mechanisms of pathogenesis and invasion of brain tumors. My current projects are: 1. Mechanisms of invasion and progression of pituitary adenomas; 2 -Refinement of the morphologic, immunohistochemical and molecular techniques for pathological classification of brain tumors; 3 – The mechanisms of glioma invasion and migration; 4 – The effects of malnutrition and specific micronutrients on intestinal, brain, and cognitive development in a murine model. Experimental techniques in our laboratory include cell culture, immunohistochemistry, immunofluorescence, and in situ hybridization.
