To display your profile in Google Search Results, you need to setup Google Authorship
How then do I setup Google Authorship?
Add a rel=author to the header section your site. You can do this easily if you have SEO by Yoast. You can download it from the WordPress plugin repository. Highly recommended if you don’t have it already.

Navigate to your Yoast dashboard, and click “Social” >> Google+
Now go to Users >> Your Profile. Scroll down to where you find “Contact Info” and fill in the Google plus URL there
Next, go to your Google Plus profile, click the About section, and make sure your website is in the “Contributor” tab. You can do this by clicking “Edit”, and adding your website to the list. Make sure it is public.
