Our motto
Nothing worthwhile is easy. Attempt the impossible, work hard, play hard, do experiments, fail fast, fail smart, do experiments. Eventually we'll create --- hopefully something worthwhile.

An intriguing question
Many of our research problems can be rephrased
as:
"How to hide a signal in a series of pulses and faithfully recover it back with little noise and distortion ? "
