Scholarly/Research Interests

Research in cutaneous sensitivity, especially investigation of the effects of the physical parameters of vibratory stimuli on threshold and suprathreshold responses in humans and their relationship to underlying neural mechanisms. The research has contributed to the identification of specific receptor systems responsible for the perception of mechanical stimuli. Research methods in psychology with emphasis on psychophysical measurement. Aspects of tactile communication for the blind and the deaf. Effects of age and gender on vibrotactile sensation.
