Personal

I grew up in Quang Binh Province in Central Vietnam, where opportunities to engage with science can be limited. This experience has made me care deeply about expanding access to science education for students from similar backgrounds. I co-founded and co-lead SEAS — Summer in Engineering and Applied Sciences, a nonprofit initiative dedicated to advancing STEM education in Central Vietnam. Each year, we bring together around 40 motivated students from underserved regions for a free summer program, introducing them to modern topics in science and engineering and mentoring them through hands-on projects.
