With immense pleasure I (Dr. Vishnu Chandrasekharan Nair) place on record, the wonderful years I have spent in IIT Madras during my PhD in petroleum engineering at its department of ocean engineering. I cherish the memories of the institute from the awestruck view of its freely roaming fauna and dense forest cover to the rigorous research years under a passionate guide (Dr. Jitendra Sangwai), life was a seamless blend of fresh hopes and well- focussed research activities. Research works, conferences, workshops, industrial projects, awards, and recognitions, whatsoever the institute as well as the department consistently drove me to dream higher and strengthen my skills and expertise. It made me now the Assistant Professor at RGIPT, Raebareli, another prestigious institute of national importance in the field of petroleum engineering, soon after the completion of my PhD. Much blessed to be the part of department of ocean engineering, IIT Madras once and always proud to be its alumni forever.
