Qianxi Wang is Lecturer of Applied Mathematics.

Qianxi has published over 20 research papers in scientific journals.

He studies on the motion of bubbles in a compressible liquid, with important applications in medical ultrasonics, sonochemistry and underwater explosion. He specialises in asymptotic perturbation methods, with application to the study of ground effect. He simulated nonlinear unsteady wave/body interaction using unstructured boundary integral method. He calculated N-body problem using fast-multipole-expansion.
