"In these forums we repeatedly see this issue: an academic resume/CV site and they rarely get indexed in Google Search.
If you really do want this indexed there are two things you can do that will dramatically increase your chance of getting indexed:
Buy and use a custom domain URL for your site
A custom domain URL will always be more unique and more relevant to your content so much more likely to get indexed.Add unique content to the site that isn't indexed elsewhere
The key to getting indexed is unique and compelling content for Google Search to index for people to search for and find. Your site is there is some text on the pages but it's probably not unique as it's already indexed (i.e. https://carey.jhu.edu/faculty/faculty-directory/andrew-ching-phd). When Google Search looks at your page it sees extremely similar content to what's already in Google Search's index so there's no reason to index it as Google Search already has that content from an authoratative source. Google Search only indexes unique and compelling textual content for other people to find: if there is very little unique text, therefore, Google Search may not even bother indexing the site as there's nothing for people to search for that isn;t already available.
This is not a Google Sites issue and the best advice is to read all the resources on:Webmaster Guidelines
ESPECIALLY
Avoid the following techniques:Creating pages with little or no original content
Hopefully that will help you improve your site's likelihood to get indexed."
