Brief writeup on area of specialization/awards/achievements:
 

Kayastha's work has led to better understanding of the mechanism of action of several enzymes from plants, their physiological and biochemical roles. He discovered a new enzyme, PEP phosphatase from V. radiata, having a role in plant starvation. His extensive work on pigeonpea urease has contributed to enhanced efficiency of nitrogen uptake by plants. He has successfully predicted the homology based structure of a-amylase from mung beans, which was on the coverpage of all issues of Phytochemistry 2008. Beyond his explicit contributions towards field of Enzymology, he has successfully implemented nanotechnology to his advantage. He has developed a novel lactose nanoprobe based on immobilization of pea ß-galactosidase onto gold nanoparticles, which was recently featured by Nature INDIA.
