Job description

Acoustic metamaterials for photoacoustic imaging

Photoacoustic imaging (PAI) is an emerging biomedical imaging modality for probing the optical properties of tissues at deep penetration depths. PAI leverages the photoacoustic effect wherein non-ionizing laser pulses targeted at soft tissues cause localized heating leading to thermal expansion and eventually wideband ultrasonic acoustic emissions.

Acoustic Metamaterials (literally meaning – “beyond materials”) are architected materials with carefully engineered microstructures to exhibit material and acoustic properties that are either tunable or exotic (oftentimes not found in nature). Supported by advances in additive manufacturing, the miniaturization of structures to material length scales enables wave manipulations such as acoustic wave guiding, tunable acoustic bandgaps, negative acoustic refractive indices, acoustic cloaking, acoustic superlensing, and many more.

In this project, these two scientific fields are combined to overcome sensitivity challenges in photoacoustic signals detection. By designing acoustic metamaterials to be used as intermediate medium between tissue and transducer, high frequency photoacoustic signals could potentially be detected and even amplified.

Your role in this project

You will work in between two departments, the precision and microsystems engineering (PME) and the material science engineering (MSE) departments. You will design and fabricate acoustic cavities for photoacoustic signal detection. As part of a team, you will build an experimental setup to test these materials. You will also develop algorithms for imaging in line with the acoustic cavities designed. Embedded in two departments you’ll find a collaborative, open and friendly atmosphere which you will foster and push even more forward.
