My name is Tanisha Williams, and I worked with Babu for several years assisting with monitoring Annex II DIW System. He trained me as Melissa Benjamin's replacement. I had much respect for him because he cared about and enjoyed his job. The irony was his stern facial expression but "very" nice personality. He was unique. Where GOD is may you spiritually be also. 

During your time of mourning, the spiritual poem FOOTPRINTS.

My condolences to the family
