Overview

Welcome to the Open Networks and Big Data Lab, led by Prof. Lakshminarayanan Subramanian.


We are a team of researchers in the Courant Institute of Mathematical Sciences at New York University, focusing on fundamental and applied research in the areas of open networking and big data analytics. In the space of open networks, we work on problems pertaining to new mobile networking stacks, programmable cellular networks, software defined wide area networks and programmable IoT platforms. In the space of big data analytics, we work on problems pertaining to crowdsourcing systems, socio-economic inference algorithms, event analytics and reputations.


Within the purview of these areas, our group specifically focuses on applications in the emerging field of Computing for Development (ICTD). The larger goal is to contribute to socio-economic development by designing innovative computing technologies for real world societal challenges. Our research philosophy places a strong emphasis on “end-to-end system design”, where we design, implement, deploy and evaluate our solutions in the real world and push successful ideas towards adoption at scale.


We are part of the NYU Systems group in the Computer Science Department.
