We make inferences about the physical properties of heterogeneous media from scattered (elastic) waves. Indoors, these waves are mostly ultrasonic, excited and detected with lasers. Outside, probing waves are in the seismic frequency band.

As our wavelengths span orders of magnitudes, so do our applications. Outside, targets include the Auckland Volcanic Field, geothermal exploration, and micro-seismicity for fluid reservoir characterization. In the laboratory, we do rock physics in collaboration with the PORO lab, ice physics, medical imaging.

  • Jonathan Simpson wins student award at the AGU meeting
    In December 2020, the AGU meeting was held virtually, and Jonathan won a best student presentation in the seismology section of the meeting with a presentation that blended a traditional "zoom-style" presentation with a tour of the setup of his laser-ultrasound experiments on nonlinear rock properties under in situ conditions. These nonlinear rock properties may…
  • Jonathan and Caitlin officially graduated
    We would like to congratulate Caitlin Smith and Jonathan Simpson with their brand-new BSc (science scholar) and MSc degree, respectively. It has been such a pleasure to work with them in our lab, that we are very happy¬† they both will continue research in the Physical Acoustics Lab in pursuit of a BSc Honours (Caitlin)…
  • Josiah Ensing's next job is to help record gravitational waves
    After a successful PhD defense, Josiah is making his next move. And it is a big one! We wish him and his family all the best in Warshaw, Poland, where he will be starting work at the seismic sensors group at Astrocent, in November 2020. Astrocent is a part of the Advanced Virgo Experiment and…
