Current interests

GLSL (OpenGL), OpenCL, multi-threaded (CPU) programming, clusters, and their applications to medical imaging and image processing. Focusing especially in the topics of data analysis, image registration, resampling, segmentation, surface modelling, atlases, DTI, and visualization.
