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.
Job Responsibility:
Design and perform experiments to study wave propagation through complex media
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
Requirements:
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
Nice to have:
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
