**Recipient:** University of Southern California

**Award Amount:** $47,328.00
**Ceiling:** $47,328.00

**Awarded:** September 03, 2025

**Identifier:** 11318674

Award for research project to develop a new method for 3D vibrometry of the inner ear using OCT, extending frequency range and accessibility, funded by NIH and managed by NIDCD.

### Description

This project involves developing a new approach to study the 3D motion of the cochlea using optical coherence tomography (OCT). The research aims to extend existing methods to higher frequencies (2 kHz-15 kHz) and make 3D vibrometry more accessible with traditional OCT systems. The project is funded by NIH grant PA-23-272, with an award amount of $47,328, and is managed by the National Institute on Deafness and Other Communication Disorders (NIDCD). The project is led by Julianna Maria Bordas at the University of Southern California.
