Description

Understanding how ultrasonic waves propagate through the human body has many important applications for AR/VR. However, this problem is still largely unexplored and extremely complex to model. Meta is leading a cutting-edge investigation in this space, relying on world-class experts. In this position, you will join Meta's ultrasonic sensing team to investigate the propagation of ultrasonic waves in complex media using both experiments and simulations, explore different ultrasound carrier frequencies, modulation waveforms, launch configurations, transducers and body coupling, and estimate fundamental wave propagation parameters, such as dispersion, attenuation, and group velocity. Our internships are twelve (12) to twenty-four (24) weeks long and we have various start dates throughout the year. Responsibilities Design and perform experiments to study wave propagation through complex media. Conduct experiments using ultrasonic transducers, laser vibrometers and/or mechanical testing techniques. Collect and analyze data from experiments using MATLAB, Python, or other software tools. Collaborate with researchers to develop computational models of wave propagation through complex media. Participate in team meetings and contribute to the development of research ideas and plans. Prepare reports and presentations on the results of experiments and modeling efforts. Assist with the maintenance and upkeep of laboratory equipment and facilities. Attend relevant seminars, workshops, and conferences to expand knowledge and skills. Minimum Qualifications Currently has, or is in the process of obtaining, a PhD degree in Physics, Engineering, or Mechanics or relevant technical field Experience with experimental techniques to study wave propagation through solid materials, including, but not limited to, ultrasound imaging, ultrasound Doppler, quantitative ultrasound, acoustic exposimetry, or laser Doppler vibrometry Experience with acoustic signal processing including, but not limited to, 2D Fourier transform, Radon transform, Ricker wavelet decomposition, dispersion relation estimation, time reversal, beam forming, or surface-wave inversion methods Experience with ultrasound guided waves and ultrasonic waveguide design Experience with programming languages such as MATLAB, Python, or C++ Must obtain work authorization in the country of employment at the time of hire and maintain ongoing work authorization during employment Preferred Qualifications Experience working and communicating cross functionally in a team environment Experience with ultrasound non-destructive evaluation Experience with finite-element acoustics modeling in Ansys, Comsol, or other similar tools Experience with ultrasound transducers including, but not limited to, coupling methods to solid materials, loading effects, matching networks, or driving-signal generation Experience with characterizing and modeling viscoelastic or hyperelastic materials, using for example, rheometers, DMAs, Prony-series or other viscoelasticity models, Yeoh or other hyperelasticity models Experience with CAD programs such as SolidWorks or AutoCAD Intent to return to degree program after the completion of the internship/co-op Proven track record of achieving significant results as demonstrated by grants, fellowships, patents, as well as first-authored publications at leading workshops or conferences $7,313/month to $12,134/month + benefits

Responsibilities
