Thank you for stopping by my website.

My name is Kai, and I am an Oceanographer at the United States Naval Research Laboratory (NRL), Washington D.C.

I am interested in:
– using transiting surface ships as sources of opportunity for the purpose of array and environmental parameter characterization
– signal and array processing in the presence of environmental noise
– development of compressive sensing techniques for source localization and parameter estimation (including sparse Bayesian learning and adaptive processing)
– passive localization of low-level acoustic sources

In my free time, I enjoy to backpack and to sail.

Quote of the moment (Press F5 to refresh):

In the great mirror of consciousness images arise and disappear and only memory gives them continuity. And memory is material – destructible, perishable, transient. On such flimsy foundations we build a sense of personal existence.
