She published work on a variety of topics in applied mathematics including viscocity, compressible fluids and transonic flows.

Turning to the mathematics of transonic flow, she showed that specially designed shockless airfoils develop shocks if they are perturbed even by a small amount.

She continued with important solo work on the wave equation and transonic flow around a profile until she was promoted to full professor by 1965.

The next step was the Euler equations, which promised to provide more accurate solutions of transonic flows.

In some cases,the total loss can be 100% due to the major key losses at transonic flow, exceeding mach number unity.

Starting in 1970, he began to concentrate on the problem of predicting transonic flow.

The Euler-Tricomi equation is used in the investigation of transonic flow.

A characteristic that is dominant in bodies in transonic flow is the concept of interference drag.

Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows.

He has written nearly 40 technical papers, most in the areas of unsteady transonic flow and aeroelasticity.
