Take a look here at the StudioPress tutorials – http://my.studiopress.com/snippets/post-info/#customize ….add that code to your functions.php file and change post_author_posts_link to post_author.
There are many more tutorials and code snippets in the “My Studiopress” link in the StudioPress.com menu. I’m mentioning this because I noticed you had quite a few posts recently (assuming you’re new to Genesis or WordPress) and that should definitely help, as most common questions can be answered by searching the StudioPress resources. It definitely helped me when I was just getting started, so I thought I’d share.
