My research mainly focuses on the geophysical characterization of near-surface processes through a wide range of methods such as electrical resistivity, induced polarization, and electromagnetics. I am particularly interested in:

• Prediction of soil behavior under dynamic forces (e.g., flooding, earthquake and heavy rain) by using novel methods for this purpose (e.g., complex resistivity and 3D induced polarization imaging). In this research, I aim to develop an early-warning system installed in-situ for monitoring unstable soils prone to landslides and shear failure. Currently, I am investigating the possibility of monitoring soil deformation and failure by complex resistivity methods.
  
  
• Designing geophysical monitoring instruments for permanent site characterizations by installing instruments capable of real-time data processing and reporting. One example is using electrical resistivity imaging in critical zones as a permanent monitoring tool to investigate the subsurface water transport in the long term. With recent advancements in computer programming (e.g., project ResIPy) and computational instruments, real-time geophysical monitoring will become the new frontier in subsurface monitoring.
  
  
• Basic science research (laboratory/pilot study) for understanding microscopic properties of soils/rocks using advanced geophysical techniques (e.g., spectral induced polarization). This will help in improving our understanding of micro-scale hydrogeological processes remotely/indirectly.
