Research Interests: 

My current research interests lie in the area of hydraulic fracture modeling and focus on understanding of the effects arising from the coupling between the fluid flow and deformation of the rock formation. In particular, my interests include proppant transport models, hydraulic fracturing numerical simulators, and multiscale effects occurring in the near-tip region of hydraulic fractures.

In addition, I have worked in the area of wave propagation with application to medical imaging. Specific topics include modeling of focused nonlinear ultrasound, elasticity imaging with acoustic radiation force, as well as gradient elastic models.
