To get to your profile, you can either, click on your image in the upper right hand corner of the page, then click on "profile". Click your profile picture on the left, or click your name on the left hand side of the screen.
If you need to Edit your Personal Profile settings, just head over to the Edit Profile link from the drop-down menu at the top right of the site header. You'll find all your options there, like changing your email or choosing your profile picture.
Note: Editing your Profile is only available from the full website and not from the mobile app for now.
