To my father, Shiv Bahadur Singh, who is a teacher and taught me the beauty of sharing knowledge, and to my mother, Nirmala Singh, who never let me stray from my focus in the face of adversities. 

To my mother, Baby Paul, and my father, Tapas Kumar Paul, who have always encouraged me to pursue the things I love and care about. To all my university juniors, who have supported me tremendously in all of my honest endeavors.
