You’re right that there’s no settings and options for what you’re seeing as this your theme’s CSS bleeding over into the plugin’s CSS and causing the avatar image to be shifted to the bottom right of the wp-biographia-pic HTML div.
If you look at your theme’s style.css around line 1172, you’ll see that all img tags within a div with the art-article class have a border of 10px applied to all 4 edges. It’s this which is causing the misplacement of the avatar’s image.
However, I can also see that the class for the avatar’s img tag contains avatar and not wp-biographia-avatar. This indicates to me that the plugin hooking into the default WordPress get_avatar() API call isn’t happening. This also could indicate that the default WordPress way of obtaining avatar images, via the Gravatar system, isn’t happening. Are you using a plugin to provide avatar images for your users?
The plugin’s CSS also doesn’t (currently) support responsively flowing the biography text around the avatar image, though this may change in a future version. You should be able to achieve this by adding some custom CSS which sets float:none on the wp-biographia-text CSS class.
