Welcome

You are at a portal page of my sites. I maintain four active websites under this domain. They are my personal website, a site for health behavior research, a site for internet technologies, and a site about my teaching. These sites are built by Wordpress blog software, or Drupal, a more powerful open source content management software. If you like you can click any of the screen shots at left to go to a specific site. You are welcome to leave a comment to this page (see below). Thank you for visiting! -Kele Ding
