Recently, Jokhongir Khayrullaev has been working on inverting subsurface P-wave velocities from time-migration velocities. He has developed several methods; as input data for the methods, temporal derivative of the time-migration velocities, Dix slowness is used; the methods leverage kinematic and dynamic seismic ray tracing for simulating the Dix slowness on the subsurface velocities. His research has focused on topics as:

• Deterministic and Bayesian implicit neural representations for velocity inversion  
• Bayesian estimation of epistemic and heteroscedastic aleatoric uncertainties
• Field validation: impact of inverted velocities and uncertainties on field data
