Research

Zhi-Pei Liang's work in the Beckman Institute is primarily focused on two areas: (1) fast and efficient magnetic resonance imaging methods and (2) intelligent computational algorithms for image processing and pattern recognition. In the first area, he and his students are developing advanced data acquisition and image reconstruction schemes to enable high-resolution spatiotemporal imaging of moving objects. In the second area, they are focusing on developing statistical and kernel-based learning methods with application, registration, and recognition.

Liang's sources of research support are the NIH and the NSF.
