Cyberinfrastructure for Discovery,
  Learning, and Engagement:
             the nanoHUB experience

                                 objectives


in this talk, I would like to:

1) Tell you who we are, what we do, and why we needed
   cyberinfrastructure.

2) Describe nanoHUB.org - explain what is it is and how we
   are using it.

3) Identify a few challenges and opportunities.

 Three reasons to simulate:

            Two kinds territory
1) to explore unchartedof results:

2) to resolve well-posed questions
         1) answers and understanding
                      Two types of scientists/engineers:

3) to make good design choices

                        outcomes


1) promote the diffusion of knowledge

2) give a researcher impact

3) provide a new avenue for “publication”

4) facilitate the use of simulation in the classroom

5) promote collaboration across disciplines



                               20
                   issues and challenges

1) finding content in a growing collection

2) permanence of content

3) quality of content

4) handling data (in addition to simulation tools and
   educational / training resources)

5) intellectual property

6) financial model for sustainability

7) people issues                21
