About

I am a PhD student in the Computer Science department at Carnegie Mellon University. I am advised by Prof. Srinivasan Seshan and Prof. Anthony Rowe.

I am working on building a world-scale federated localization and mapping system called OpenFLAME. OpenFLAME enables the next generation of location-based applications, including large-scale mixed-reality, taking us closer to the dream of the Spatial Web – the web where data is associated with and rendered against physical spaces.

I also worked with Netflix on designing the bitrate ladder algorithm for 2D video streaming that is in the process of being deployed. Previously, I worked at Microsoft Research on building a large-scale data discovery framework and optimizing inter-datacenter network.
