Online simulation tools and presentations
The scope of current research has become inter-disciplinary and has diversified extensively over the last decade or so. As such, disseminating the research through a series of publication is believed to have real impact only when associated simulation materials and detailed research notes are also made available. To serve this purpose, recently NSF and DOE has funded such outreach programs like nanoHub, SciDAC. I have taken this opportunity to circulate my research tools and presentations to the users for free at nanoHub (see my user profile at Nanohub ).
My main contribution in nanoHub involves uploading the following tools, publications, and research presentations for general access.
