Peter Cariani’s training and work has involved theoretical biology, biological cybernetics, and neuroscience (B.S. 1978, MIT, biology; M.S. 1982, Ph.D. 1989, Binghamton University, systems science). His doctoral work developed a semiotics of percept–action systems, formulated a taxonomy of selfconstructing adaptive systems, and explored epistemic implications of evolutionary robotics. Currently a Clinical Instructor in Otology and Laryngology at Harvard Medical School, Cariani also teaches courses related to music perception and cognition at MIT and Tufts University. In 2009 he edited a book on architectural acoustics by Yoichi Ando, Auditory and Visual Sensations. He is currently engaged in auditory modeling and neural timing net research as part of an auditory scene analysis project at the University of Rhode Island.
