The Hearing Epidemiology and Research Diagnostics (HEARD) Laboratory, led by Principal Investigator Dr. Rachael R. Baiduc, explores the connection between hearing loss and cardiovascular disease risk factors. Both hearing loss and cardiovascular disease are prevalent chronic conditions and the hearing system has a demonstrated vulnerability to cardiovascular-related insults. The HEARD team explores the effects of risk factors including diabetes, hypertension, high cholesterol, and tobacco and marijuana smoking on auditory function. Currently, Dr. Baiduc is supported by a grant from the American Hearing Research Foundation and is using machine learning to explore sex-specific audiometric phenotypes in persons with cardiometabolic risk factors. Previous research was supported by grants from the Hearing Health Foundation and CU Boulder Innovative Seed grant.
