18.       Technical Proficiency

For the last 34 years, I am engaged in research pertaining to cytogenetics and systematics of Angiosperms. I have published more than 96 research papers on taxonomy, forest vegetation and cytomorphological diversity. I have guided 7 Ph.D. and 5 M.Phil. students. Four students are pursuing for their Ph.D. degree mainly on the cyto-morpholgical diversity, germplasm evaluation and reproductive biology. I am incharge of Herbarium & Museum which is internationally recognized and is an important component of the department.
