Show Posts in full length?

Hi,

I want to create a page to display several scientific research groups sorted by their fields of expertise and research. Because many groups have several fields of research, I thought that it would be good to do a post for every group that can have several categories. Then I wanted to do pages for each research area and display there all research groups (= posts) with the corresponding category. I would like to have all research groups of a specific area, i. e. all posts with a certain category, displayed completely on the respective site (so there is no need for the reader to click on the individual posts). It should look like a nice list of groups (and not like a blog), but with the advantage that I can change details for one group only once and then every list is updated.
Is it possible for the Skyline Theme to display whole posts on one page? I only was able to change the length of the summary, but not to choose to display the whole post.

I’d appreciate every help!

Thanks, Clarissa
