Research is a creative process that is substantially enhanced by valuing, encouraging, and experiencing a vibrant, diverse group of individuals who support each other. We value and foster an inclusive environment by actively incorporating an open, supportive mindset while cultivating a culturally rich and diverse group dynamic. 

At Lehigh, we are actively involved in the department and student-led initiatives to listen and grow further to become a more diverse, equitable, and inclusive community. We strive to overcome barriers together that are presented to first-generation students and students coming from disadvantaged backgrounds. The strength of our group is mirrored in the individuals’ success and our collective, communal effort to support everyone to become the best version of themselves on an academic and a personal level so everyone can grow to become respected and admired leaders.
