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.

  • 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…
  • Seismology in the time of Covid-19
    Today, a new paper came out in Science showing that in many places around the globe the noise levels on seismic stations dropped dramatically after lockdown measures to combat COVID-19 went in effect. The study was led by colleagues in Brussels, but Kasper's involvement kept him busy when our campus was closed, and the result…
  • Photoacoustic imaging in a bone model
    Mainstream photoacoustic imaging methods approximate the human body as a fluid.  This assumption is reasonable for soft tissues, but breaks down for bones.  Cortical bone is a stiffer material than soft tissues, with a wavespeed that is dependent on the direction of wave propagation (anisotropy).  We have recently developed a new method for reconstructing photoacoustic…
