Software:

I am the principal developer of HIGHLY SPECIFIC BUT EDGILY EFFECTIVE DATA-PROCESSING (HI-SPEED) SOFTWARE PACKETS (http://sites.google.com/site/hispeedpackets). A poster showcasing the HI-SPEED software packets was presented at the 2009 ISMRM Educational Session, click here to download the poster. The site also contains several brief notes on various topics related to my research. Although the core routines of HI-SPEED are written in Java, special interfaces to these routines in other programming languages such as IDL, MATLAB and Mathematica are also available.
