Dr. Jeffrey Cheng is an Investigator in the Eaton-Peabody Laboratories at Mass. Eye and Ear/Harvard Medical School. His primary research interest is tympanic membrane physiology and function. Using newly developed laser holography techniques, his laboratory measures the shape and sound induced 3-dimensional motion of the entire surface of the tympanic membrane (eardrum), in both magnitude and phase in a number of mammalian species.

To further our understanding on the working mechanism of the tympanic membrane, Dr. Cheng also investigates how the tympanic membrane reacts to the reverse mechanical stimulation of the ossicles produced by, for example, an active middle-ear implant. A detailed analysis of tympanic membrane surface motion by holography on pathological ears could benefit diagnoses of middle-ear diseases and help plan for preoperative treatment as well as post-treatment evaluation. 

Dr. Cheng also collaborates with optical experts at Mass General and Physical Science, Inc., Andover to develop an Optical Coherence Tomography (OCT)-based middle-ear diagnostic device that can non-invasively detect and measure morphological information and dynamic vibration of middle-ear structures in normal and pathological ears through the intact eardrum.
