BuddyPress.org

Im really new to php and wordpress. I wanted to figure out howto change a link which goes to an authors posts and make it bring up the authors Buddy Press Profile. I am making changes to the Author box on my website which is a part on the sidebar that displays the authors avatar. Im trying to make changes to this. to no avail. any help or other post references would be great. I havent seemed to find an answer yet. Thanks.

<?php
    if( !isset( $post ) ){
        return '';
    }
    $meta = meta::get_meta( $post -> ID , 'settings' );

    if( isset( $meta[ 'author' ] ) && strlen( $meta[ 'author' ] ) && !is_author() ){
        $show_author = meta::logic( $post , 'settings' , 'author' );
    }else{
        if( is_single() ){
            $show_author = options::logic( 'blog_post' , 'post_author_box' );
        }

        if( is_page() ){
            $show_author = options::logic( 'blog_post' , 'page_author_box' );
        }

        if( !( is_single() || is_page() ) ){
            $show_author = true;
        }
    }

    if( ( is_single () || is_author() || is_page() ) &&  $show_author   ){
