Citing my own work in my Statement of Purpose

[bobdogs20]

Hi, 

I am applying to PhD programs in Biomedical Engineering. I want to cite my papers in my Statement of Purpose. This was advised by my current research advisor. How should I do so, I dont want to keep bothering him. Currently, I have: 

Then I have a references page at the bottom. Are there other ways to do so? Also I am not a first author on these papers, I am second and 4th for context. 

 

Thank you in advance.
