Biography

Prof. (Dr.) G.S. Shekhawat’s research involves various aspects related to plant biotechnology, molecular biology and stress physiology. He also studies biochemical aspects of medicinal and aromatic plant species and there in vitro propagation and conservation, specifically rare and endangered plants of Indian Thar Desert.

Prof. Shekhawat completed his PhD from University of Rajasthan, and since then continuously engaged in research; initially started as a CSIR Post Doc Fellow, BOYSCAST fellowship and worked at University of South Florida, USA. Dr Shekhawat has also been awarded by INSA International Exchange Fellowship, Young Research Award, Professor YS Murthy Gold medal award by Indian Botanical Society. He has also completed several research projects funded by several national and international funding agencies.

Prof. Shekhawat has published several books and more than 65 research papers/articles in journal of international repute. Presently Prof (Dr.) Gyan Singh Shekhawat is working on Heme oxygenase-1 (HO-1), Nitric oxide (NO) signaling in plants and in vitro production of medicinally potent metabolites.
