Research Theme

Clinical and Veterinary Neuroscience


My current interests include hardware and software development for various medical imaging modalities, especially PET and MRI. This work is done in close collaboration with the Wolfson Brain Imaging Centre. One particular current project is the development of a novel combined PET-MR system for pre-clinical research. Other projects involve MR sequence development and post-processing algorithms for MR and PET. I also have interests in high performance computing, including parallel programming on PC clusters GPUs. A 3D image registration tool, AIRWC is available from my website which runs on CUDA enabled GPUs. I am also interested in graphical applications including the visualization of complex data sets.
