Roger W. Cholewiak

Dr. Cholewiak arrived at Princeton University from the University of Virginia as a Research Associate in 1974 and is now the Director of the laboratory. His research interests have primarily involved the variables underlying how the skin processes two-dimensional patterns presented with vibrotactile matrix systems. The majority of his work has employed arrays of mechanical contactors of his own design fitted to different body sites. He is internationally known in the area of tactile transducers, co-authoring a book chapter on vibrotactile transducers, and has consulted in the successful development of new tactor systems with Sensor Electronics (Medford, New Jersey) through NIH SBIR grants (the MTAC, an ultradense vibrotactile array, and the Roto-Oscillating Crown tactor, a powerful tactor with a unique set of stimulation modes). He has authored 6 book chapters and encyclopedia articles on tactile sensitivity as well as over 2 dozen journal articles and presentations at national and international professional meetings. He has been a consultant with government institutions, including the National Institutes of Health and the National Academy of Science, educational institutions, the military, and commercial laboratories.
