DIA2 is out of beta!

Screenshot of DIA2 showing multiple toolsI am so pleased that we launched the redesign of  DIA2 and the new homepage this weekend! It’s been a long and fun journey!

DIA2 is a Web application for knowledge mining and visualization of the NSF funding portfolio. Anyone can use it to explore where NSF funding goes, how it’s distributed geographically, across NSF divisions, across topics, and institutions. You can explore collaboration networks of researchers who worked together on proposals, identify who’s well connected in a field, and figure out what NSF programs and program managers have funded research similar to yours.

I’m happy to have been involved with DIA2 since the very beginning, as a co-Principal Investigator (co-PI). I led the UX team for the project. We started with user research to understand user needs, and moved through ideation, wireframing, testing, the whole 9 yards. It’s been very rewarding to hear users say, “This thing reads my mind!” and “I feel it was designed for ME!” Perhaps best of all, DIA2 gave me the opportunity to work with and mentor many talented students. All DIA2 “employees” have been students working under a PI’s supervision. I am so proud of them!

If you’d like to, go check DIA2 out for yourself – it’s available for all at
