Janender has been a good friend since my days at National Institute of Oceanography.
He is a dynamic field and lab geologist. Hard working and diligent. He would work or study till late night to complete his dissertation on Foraminifers. Having been his roommate was a pleasure. I would discuss my dissertation on Marine Algae during monsoon and work out ways on solving each other problems.

Above all he is a person good at heart, patient, honest opinion, critical at times, lively and fun person to be around. You would love Him as your Superprof, Guru and Friend.
