Go to Theme Options -> Page to manage default settings for page sidebar and layout.
Also, you can edit these options for each particular page separately.
Page Layout
You can choose 6 layouts for a page. Page layouts are very similar to single post layouts with the main difference that pages doesn’t have metadata so layouts with vertical meta bar variations are not available here.
Page Sidebar
Just as for each post, you can set a specific sidebar for each page.
More about sidebars is described in Sidebars sections of this documentation.

As described on image below, you just need to select the Author template and follow its options.
