Dr. Lakshmanan Senthilkumar was raised in a middle-class family in Chennai, Tamil Nadu, with a mother who is a Tamizh teacher and a father who works as a hardware engineer. He finished his undergraduate studies in medicine and science at Madras Medical College, one of India's most prominent universities that was founded during the British Raj.

He had a lifetime passion for math, especially geometry, series, and calculus, and he was particularly interested in the works of Albert Einstein, Abdul Kalam, and Srinivasa Ramanujam.

He practiced science while getting his degree, and a complete belief in Physical Chemistry for medicine and health, that encompasses the activities we do in a day. His contributions to this book are also centered on physical chemistry.
