Customizing 'About the Author' section?

I was wondering if there is a way to customize the ‘About the Author’ section that is under the posts (CSS Class – .author-info)? I was wondering if it could be modified to have the Avitar, the author’s name (which links to their profile – or for me, link to the ‘About Us’ page), and the link for ‘View all posts by Author →’. so it appears like this:

<table border="0" cellspacing="5" cellpadding="0">
  <tr>
    <td width="100" rowspan="2" align="center">Avatar<br>Image</td>
    <td height="50">Name of Author (links to Author's profile, or if I'm the poster, links to my about us page)</td>
  </tr>
  <tr>
    <td height="50">View all posts by Name of Author →</td>
  </tr>
</table>

Thank you.
