Anthony Melvin Crasto Ph.D (Worlddrugtracker, Principal scientist, Process research, Glenmark-Generics ltd & founder of several linkedin gps) :
"DR Umesh is a person who always shares with others and is evident in his blog MED-CHEMIST, he takes effort to post new info every morning at 6.00 am. This is one quality which I rate in high esteem. He led a team of 25 scientists in Innovassynth and was a very dynamic man, good leader and visionary. He is kind by heart and hope to meet him in Tumkur some day".......
February 19, 2013, Anthony Melvin worked with Dr. Umesh at Innovassynth Technologies Limited, Khopoli, (formerly, Indian Organic Chemicals Limited)...
