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. Experimental techniques in our laboratory include cell culture, immunohistochemistry, immunofluorescence, and in situ hybridization.
