Research interests include: 1) basic research on auditory perception in animals, particularly in the area of auditory psychophysics in non-human primates. 2) the effects of drugs of abuse on perceptual and motor function in non-human primates. Studies combine the techniques of animal psychophysics with the methodologies of behavioral pharmacology to provide an animal experimental model of the clinical effects of drugs, including drugs of abuse, on auditory perception and motor function, and have provided a description of perceptual/motor "profiles" of drug effects that can differentiate among many drugs. 3) The behavioral consequences of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) and drug use. 4) The effects of space flight on human performance, with currently funded research involved in the development of an interactive, computerized, multi-person simulation for modeling psychosocial performances within and between space-dwelling and Earth-based groups.
