If you ever visit Pennagaram village in Tamil Nadu border, you may come across forty-something Hari Nath toiling in his fields. You are most likely to brush him off as just another farmer unless you google Dr Hari Nath Kasiganesan. A drug researcher of global repute, he left his lucrative job as a high-profile drug scientist in USA to promote organic farming and traditional medicines in his village. His humility, which he professes to be inspired by his former supervisor Dr APJ Abdul Kalam, is rare to find in a dignitary of his stature.
