Lakshminarayanan Subramanian

Lakshminarayanan Subramanian is a Professor in the Courant Institute of Mathematical Sciences at NYU. His research interests are in the areas of networked systems, big data analytics and computing for development. He is a member of the NYU Systems group which investigates software solutions for distributed systems, wireline and wireless networking, operating system, security and privacy, technologies and applications for the developing world. He co-established the Center for Technology and Economic Development (CTED) at NYU Abu Dhabi which brings together students from several disciplines (CS, economics, healthcare, education, policy). He is the recipient of several awards including the NSF CAREER Award (2009), Google Faculty Award (2013), IBM Faculty Award (2009, 2010) and C.V. Ramamoorthy Award. He has been at the forefront of several technological innovations for development that have been used in several countries around the world. Many of his research works are now being commercialized by startups established by his students. He is the co-founder of Entrupy Inc (surface fingerprinting).

His research is supported in part by NYU WIRELESS.
