As you can see for yourself by viewing
http://blogs.oregonstate.edu/treetopics/feed/ ,
the title is already duplicated on Wordpress.
If you google for 'feed title duplicated wordpress' , you'll see that it's not an uncommon problem.
Not the first time the issue has been posted here either:
Of course for email subscribers of the feedburner feed, you can customize the title in
feedburner settings in Publicize / Email Subscriptions : Email Branding
For the feedburner atom feed subscribers, edit the feed title in feed details
or enable Optimize / Title/Description Burner.
