It is with the most profound sorrow that I must write to you about the loss of our friend, collaborator, teacher and esteemed member of the High Energy Physics community.
The end came quite suddenly after a series of health problems, first in the form of lung infections and eventually cardiac arrest. I met him recently in December in Chennai at which time he was planning a holiday to Bali and Singapore. Apparently he had been recovering from a lung infection, but on his return there was a recurrence and he spent many weeks in the ICU. I spoke to him last month and he sounded a little tired, but apparently otherwise he was getting better. It seems that these infections had weakened him to such an extent that he had a set back.
Rahul was known to many of us for his organizational skill and enthusiasm in organizing schools, conferences, workshop, etc.. Some of our own students have recently heard his lectures in Chandigarh, and he was to lecture in April at the SINP school. For others he was a collaborator and friend to many of us. Recently many of us have known him for his blogging on As I Please, where his powerful language and logic and wit speak for themselves.
At this stage I have very few words left to say. I would like to request you all to join me in my thoughts and pay our respects to his memory.
