When I called him up yesterday morning on his cell, to invite him for some function, that soothing voice on the other end was no longer there. He had left all of us the very same morning. I am at loss of words. To me Dr. Sundararajan was an 'un-official' mentor during my Ph.D. program. Although I had quite less academic overlap with him, he always used to help out in umpteen ways, particularly when it came to using the C-DAC facilities for our research work.
He almost always used to attend my Ph.D. progress presentations and had ready useful comments at the end of the session. After I had completed my thesis, he had asked me to give a presentation at C-DAC, which unfortunately never happened as I almost immediately went to ANU for post-doc.
Even when Dr. Sundararajan went into higher administrative roles at C-DAC he was always accessible to everyone who had an interest in doing interesting work with HPC and evolutionary algorithms. He also taught courses at my alma mater, and would indeed be a great loss as a teacher.
R.I.P. may god give his family strength and courage for the life ahead.
