This interest is not only reflected in her academic pursuits but also in her hobbies and extracurricular activities, underscoring her dedication to fostering inclusivity and opportunity in these areas. 
Following her recent experience with Getaway Growth’s Summer Intercultural Competence and Service Learning Trip, where she witnessed alarming levels of ocean pollution during a beach cleanup, J-Min was inspired to pursue her long-held goal of obtaining her scuba diving certification. Now equipped with this skill, she is supporting community-driven initiatives focused on ocean conservancy and sustainability efforts.
