Dennis M Freeman

Professor Dennis M Freeman is a faculty member at the School of Engineering, Massachusetts Institute of Technology, where he holds a joint appointment in the Department of Electrical Engineering and Computer Science. His research focuses on understanding the cellular and molecular mechanisms of human hearing, particularly through studying the tectorial membrane and its role in auditory sensitivity and selectivity.

• Discovered tectorial membrane wave dynamics' contribution to hearing properties
• Developed motion microscopy for nanoscale motion analysis
• Investigated age-related CEACAM16 loss effects on auditory function

His work addresses critical gaps in hearing remediation by targeting fundamental auditory mechanics rather than symptomatic treatments.
