Research Interests:
My major area of research has been detection theory, which leads to a reasonable expertise in the fields of statistical communication theory and statistical signal processing.

Within detection theory my most recent thrust area has been decentralized detection which is known variously as distributed detection and data fusion, and involves the integration of groups of sensors (radar, sonar, etc.) into a high performance unit. Additionally, I have been involved in research in modelling of nongaussian noise processes, with applications to undersea observations and atmospheric observations.

I have also had activity in the detection and estimation of harmonic sets, which effectively means the identification of rotating machinery; in robust detection, which is the design of hypothesis tests when noise/signal conditions are only partially kn own, and (on a theoretical level) in optical signal processing.

Other research interests: statistical communication theory.
