Research
In my research I study mechanical behavior of faults and fractures during underground water injection, as well as the induced seismicity and microseismic activity associated with them. I use numerical modeling of fluid flow and dynamic rupture propagation in deformable porous/fractured/faulted media to analyze the registered seismicity. Another aspect of my research focuses on implementation of machine learning regression algorithms as well as Bayesian inversion techniques to learn about stress state, frictional parameters of faults/fractures and hydromechanical properties of the medium.
