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 am also exploring other research directions. I have two current interests: Communication and Networking and Data Science. Within these broad topics, I have two major projects. (a) Representation Learning (applications: NLP and communication/networking algorithms); (b) Anonymity networking technologies (application: cryptocurrencies).

Anonymity Preserving Technologies

  • Differential privacy: staircase mechanism cut+replaces Laplace mechanism and universally improves utility, optimal composition theorems.
  • Metadata privacy: Rumor source hiding in social networks: Spy vs Spy formulation, Sigmetrics 2015 (best paper award).
  • Ventrilocation: making LTE phone calls without revealing your location (too precisely).
  • Dandelion: redesigning Bitcoin networking for anonymity.

Representation Learning: NLP

Theoretical Data Science

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.
