Research

I have worked actively in wireless communications for well over a decade, with research involving building models to designing algorithms to system solutions to entrepreneurial and industrial implementations. I am partial to the theoretical and conceptual aspects of the problems I work on.

With wireless technology fairly mature, I have explored other research directions. Recent interests have included Data Science, specifically Representation Learning (applications: NLP and communication/networking algorithms). My recent research interests are in a first principle understanding and design of blockchains.

Current: Full Stack Design of Blockchain Technologies

  • Prism: a consensus algorithm that meets information theoretic limits on throughput, latency, reliability -- a roughly 3 order improvement over Bitcoin, while maintaining same security guarantees.
  • Polyshard: a coded sharding architecture for scalable storage in blockchains; brings up the role of coding theory for distributed computations in blockchains.
  • Spider: an off-chain networking stack bringing best practices of data networking (routing with cycles!) to blockchains.
  • Dandelion: redesigning Bitcoin networking for anonymity. Network-level anonymity properties in Bitcoin.
  • Incentives: equitable designs for proof of stake blockchains.

  • Recent: Representation Learning: NLP

    Past: Wireless Communication

    I have worked on algorithms for scheduling users in cellular networks, MIMO algorithms, interference management solutions and a variety of topics in wireless communication over a decade and a half of research. I was one of the early designers of Flash-OFDM, the first OFDM based cellular system (at Flarion Technologies) and coauthored a popular book on wireless communication.
