Line of Research

My research line addresses the connections between public health and adult education to prevent health disparities in marginalized populations. I am also interested in developing research to inform and influence policy and laws for adult education for immigrants in the United States. I consider a holistic approach to have a complete impact on a community's health, well-being, quality of life, and opportunities for all.

What does the Holmes Scholars Program mean to you?

I believe in the power of community. I believe that being part of a group of doctoral students from historically underrepresented backgrounds is empowering. Furthermore, I desire to be part of a community that encourages mentoring, peer support, and professional development of underrepresented scholars. I hope to contribute to the Holmes Scholar program with my international experience and leadership to have a positive influence on American education. I am deeply motivated by a desire to work in a learning community that is preparing the next generation of life-changing scholars and leaders in the United States.
