Puneet Khandelwal

Senior Research Fellow, Physical and Material Chemistry Division, CSIR-National Chemical Laboratory, Pune, Maharashtra-411008, India.

Research Interest

I am Puneet Khandelwal, student from Biotechnology background (M.Sc and B.Sc in Biotechnology) likes to address challenging problems. I believe in team work and interested to work at the interface of Physics/Chemistry and Biology (Nanobiotechnology) because it gives me an oppurtunity to explore my learnt skills for different application purposes. I worked on project entitled “Biosynthesis of metal/metal oxide nanoparticles and measurement of their physical, biophysical properties” during Ph.D. This project gave me an opportunity to extend my expertise beyond biological science.
