My most recent research has been in the area of information theory and its applications to coding, especially data compression. I am also interested in problems of information systems and patterns of information use. These include using the Bayesian decision theory to model retrieval decisions and seeking forms of distributions that describe artifacts of information generation in a manner resilient to ambiguity. (Methodology and Quantitative Psychology).

My research centers around factors (stimulus and experimental) which influence auditory space perception. A main concern has been to find out how we use spectral cues to localize sounds. The phenomenon that stimulus frequency has a referent space which aids us in our location judgments has been the top item in my research agenda. More recently, some work is being carried out on hemispheric asymmetries in the localization of sound in space. (Biopsychology)
