Sivasankar Nair

I am a final year Ph.D. student at the Département de Mathématiques et de Statistique of the Université de Montréal. My supervisor is Prof. Matilde Lalín, and I am working on special values of L-functions and Mahler measures. I am one of the many people working in Number Theory in the vibrant city of Montréal! I was previously a Master's student at UBC, supervised by Prof. Sujatha Ramdorai and Prof. Vinayak Vatsal, and an undergraduate student at IIT Kanpur.
