Saurabh Mukherjea, 

When travelling, Mukherjea passes time by trading math exercises with his young children. In his day job, he is one of India’s finest arbiters of corporate governance and a master picker of clean stocks. His brand of ‘forensic accounting’ hasn’t brought in a revolution, but it has nudged companies enough. Just five years ago, one in five S&P BSE 500 companies had serious accounting lapses. Now, the number of errant companies has come down to below 20.
