Main research interests in two areas:
In the area of Physics with Life Sciences Interface, we develop advanced computational methods for image processing and analysis and work with biologists and medical physicists to apply these techniques to fluorescence microscopy and ultrasound images. This includes a new image restoration method, called translation microscopy (TRAM), for super-resolution microscopy imaging. TRAM can improve the resolution of diffraction limited images from a confocal microscope to the level of the state of the art STED super-resolution microscope. We have been further developing new algorithms capable of detection and tracking of transport particles within biological live cells and microbubbles in contrast-enhanced ultrasound (CEUS) images.
In Atomic, Molecular and Nonlinear Optics, we study the nonlinear phenomena of cold atoms and molecules in novel optical fields. Our aim is to understand and exploit their collective dynamics arising from the nonlinear interactions for applications, such as deceleration of cold molecular beams.

Weiping joined Heriot-Watt in 1988 as a China Research Fellow under the Royal Society and Chinese Academy Exchange Programme. He obtained his PhD from Heriot-Watt in 1991 on nonlinear dynamics and chaos in optical systems and then worked as a postdoc in the same subject area. He received the 67th Award of the Makdougall-Brisbane Prize in1998 by the Royal Society of Edinburgh for his contributions to this subject. He was appointed a Lecturer in 1997 and is now a Reader in the School of Engineering and Physical Sciences.
