BuddyPress.org

I am using BP 1.5.1. – using a child theme based on the standard theme.
I have successfully created a submenu called ‘blog’ – this is displayed next to Activity/Profile/Friends etc etc
I want to create a simple loop to display all posts for that particular user. I’ve tried various things but cannot seem to populate the posts for the ‘loop’
e.g.

while ( have_posts() ) : the_post();
echo '<li>';
the_title();
echo '</li>';
endwhile;

Can someone help? I can add complexity if I can get access to the basics
