In turbulence, he developed universal probability density function for turbulent velocity fluctuations, Reynolds stress and conditional Reynolds shear stresses in wall-shear flows.

Although acoustic Doppler velocimetry ( ADV ) has become a popular technique in laboratory in field applications, several researchers pointed out accurately that the ADV signal outputs include the combined effects of turbulent velocity fluctuations, Doppler noise, signal aliasing, turbulent shear and other disturbances.
