Researcher Mozilla Mixed Reality Team


Full Time Graduate Researcher, part time hacker and FOSS enthusiast.

I work with Mozilla Research Mixed Reality team to make WebXR run faster.

I used to write code for Watson and do a bunch of other things at their lab (mostly deals with algorithm,NLP, Ontologies,reading papers, procrastinating and lamenting about how little I know, among other stuff).

Also a PhD student at Rice University

A rolling profile

I am also a Mozilla Pilot Tech Evangelist (but that's a different story).

Teams I work with:

  • Security (MIG)
  • Fennec (Chota fennec)
  • MozVR (A-Frame)

My present interest deviates towards security. Primarily static analysis and marginally towards systems.
