how do i add author name on the blog posts on home page

Hello, This theme is awesome, I ma just running into a bit of a snag and cant find an answer anywhere.

The way the blog is setup the home page is where all of the blog posts go. I would like to be able to see the author underneath each post. Right Now i can only see the author if i go into the post or though archives. But since this shows the recent activity on my home page i want it there as well. I appreciate your help.
