I am a senior research scientist working for Schlumberger's research lab in Cambridge, Massachusetts, USA. I work on communication systems for remote geophysical measurements and manipulations over a variety of medium: pressure pulse propagation, acoustics, EM, etc.
Sampling theory: I have contributed to the theory (and perhaps practice) of signal acquisition based on the finite rate of innovation framework.
Information theory of databases: I have an ongoing collaboration with MIT on the information theory of databases, or more specifically on synchronizing different versions of a document.
Multi-user communication: I did some work on multi-user communication, but no longer have an active research effort (at least not in the public domain).
All the images that I uploaded are my own personal photos, and I release them under GFDL, unless otherwise noted. Please don't just indiscriminately delete my images off Wikipedia just because they were uploaded before I had a chance to tag them.
