Research Interests

  • Inversion of geophysical data set (e.g., gravity, gravity gradiometry, magnetics, DC, IP, MT, EM, seismic traveltime) constrained by geological prior information.
  • Joint inversion of multiple geophysical data sets based on structural similarity and prior petrophysical measurements.
  • Sparse inversion using L1 and L0 norm regularization.
  • Magnetization vector inversion with clustering constraints.
  • Machine learning, such as neural networks and deep learning, applied to geophysical problems.
  • Sparse signal processing of geophysical data.
