I devised a method for clinical ear-canal reflectance measurements, and performed reflectance measurements comparing infant and adult ears. These results have found application to assessing conductive influences on outcomes in newborn hearing screening programs to detect hearing loss. A new approach to measuring evoked otoacoustic emissions extended the ability to measure responses to much higher frequencies. For example, we showed that suppression of stimulus frequency otoacoustic emissions provide a non-invasive measure of cochlear nonlinearity. These experimental studies were supported by parallel modeling efforts to better understand maturational changes in ear-canal and middle-ear function, to explain how middle-ear function affects the interpretation of measures of cochlear function, and to construct more accurate models of human middle-ear mechanics. My current research involves collaborations between basic and clinical trained researchers to advance the clinical diagnosis and monitoring of middle-ear and cochlear function. I have served as PI on multiple NIH and other grants. I have advised four doctoral students during completion of their dissertations, and have mentored five postdoctoral fellows. I am currently chair of the BTNRH training committee and PI of our institutional training grant.
