1.High-Resolution Acoustic Tomography – Developing traveltime and Full Waveform Inversion (FWI) algorithms to enhance subsurface imaging, including processing of field data from latest-generation acoustic logging tools.
2.DAS-Based Cement Evaluation – Leveraging Distributed Acoustic Sensing (DAS) data and tube-wave propagation analysis to assess cement integrity and zonal isolation in cased-hole environments.
3.Azimuthal Anisotropy Characterization – Integrating numerical ultrasonic reflection modeling with experimental validation to quantify azimuthal anisotropic formation properties.

Developed a joint inversion workflow to enhance the estimation of pore shapes and their fractions in carbonate rocks by combining T2 distribution and rock physics models.

Developed a borehole acoustic reflection traveltime tomography method to reconstruct velocity distribution within 10 meters away from the borehole by using monopole reflected arrivals from subsurface reflectors.
