Dynamic systems of fluid-solid interaction have been of use in many areas, such as flow of blood in artery, mechanical engineering and computer graphics etc. Working with Jean-Christophe Nave in the Department of Mathematics, we developed a methodology to numerically model the dynamic interaction between fluid and solid by using Finite Difference method with Level Set method.

By using Finite Difference and Finite element methods, I focus on studying the dynamic and static elastic properties of porous and fractured rocks numerically with digital rocks obtained from x-ray CT scan.

3. Numerical Modeling of Seismic Wave Propagation
I am interested in difference methods of numerical modeling of seismic wave propagation in arbitrary media.

4. Seismic Scattering from Fractured Reservoirs
I have studied the seismic scattering energy from discrete fractures and used this energy to extract the information about fractures, like orientation and spacing.

5. Geomechanics of Fractured Networks
I study the geomechanic responses of fractured networks and their manifestations on seismic anisotropy and permeability.
6. Seismic Anisotropy of Fractured Reservoirs
I study the AVOaz of fractured reservoir and the seismic signatures due to fracture-induced anisotropy.
7. Fault Deformations of Earthquakes
I study the coseismic displacement along faults during earthquakes with considering effects of earthquake cycles, faults segmentation and rheological properties of lower crust and upper mantle.
