My Mentors: The place before god is only for teachers, parents give birth to you but your life is decorated by the teachers.  These people always supported me without any personal benefit. I thank  Prof. Anshuman Kumar ( My Ph.D. supervisor), Prof. Anchal Srivastava, Prof. Poonam Tandon, Mr. Alkesh Verma, Mr. Ramesh Singh, and Mr. Abhishek Pandey (left to right).

Friends:  This is the relationship that we build on our own. I thank  Sonam (my sister), Jyoti, Arpit,,Lekshmi, Kishor, Brijesh, and Abhishek and my Family  (left to right), for being there with me in my good and bad times. I had good discussions as well as a fun time with these guys.
