Exclude custom function content from certain pages

Check for the type of the page:

function get_author_bio ($content=""){

    if ( ! is_single() ) // not a blog post, stop immediately
    {
        return $content;
    }

    global $post; // continue with regular work

The easiest way to learn these check functions is a look at the function get_body_class(). Here are the most important:

is_rtl()
is_front_page()
is_home()
is_archive()
is_date()
is_search()
is_paged() 
is_attachment() 
is_404() 
is_single() 
is_page() 
is_singular() // same as is_page() and is_single()
is_attachment() 
is_archive() 
is_post_type_archive() 
is_author() 
is_category() 
is_tag() 
is_tax() 
is_user_logged_in() 
is_admin_bar_showing()

You can even combine them:

// search results, not the first page
if ( is_search() and is_paged() )

// attachment and user has probably a profile
if ( is_attachment() and is_user_logged_in() )

Some of these functions accept parameters to restrict the result:

// contact page only
if ( is_page( 'contact' ) )

// this post was written by the tooth fairy
if ( is_author( 'tooth-fairy' ) )
