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.

My research carried out at the NIH was supported in part by the Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

My heartfelt gratitude goes to my current and former mentors for their support and guidance:

Peter Basser, Carlo Pierpaoli, Andy Alexander, Beth Meyerand, Brett Esry, Mike Crescimanno, Jay Baltisberger, Amer Lahamer, J. P. Lee, James Lynch, Hon Yew Chong, Poh Im Toh, Eng Khoon Leong, Geik Kee Tan, Lean Choo Khoo.
