I am currently a Postdoc at National University of Singapore. I completed my Ph.D from the Department of Computer Science and Engineering at IIT Madras. I received my Master's degree (2011) in Computer Science and Engineering from IIT Bombay, and my Bachelor's degree (2009) in Computer Science from Anna University. I have also worked at Intel, Bangalore, during the period 2011 to 2014, where I was involved in the development of a functional model of Intel's graphics processors.

During my Ph.D., I have developed solutions that an administrator of a multi-vendor network can use for network management. Specifically, my thesis addresses the dearth of reliable tools that can (1) authenticate devices, (2) measure their QoS, and (3) log critical events. I am fortunate to have Prof. Kamakoti Veezhinathan and Prof. Chester Rebeiro as my advisors. Also, I have had the privilege of being mentored by Prof. Byrav Ramamurthy (UNL), Prof. Pratyush Kumar (IITM), and Prof. Nitin Chandrachoodan (IITM), on various projects.
