Cultural Disparities/Underrepresented Pop. Theme

Hi I’m a second year undergrad and thought it would be a good idea to start building my application around a theme. My theme is going to be my interest in advocating for women of color in medicine like myself and bridging cultural disparities as I am a first generation American (and first gen college student).

However I’m having a hard time on how I can hyper focus on this…? So far I have a leadership position in an women’s health org at my school, and i’m planning to pursue a research position that deals with underrepresented groups in healthcare. Is there anything else that I should be involved in..? I’m just looking for more ideas. Thanks
