Introduction

From an early age, I showed a natural inclination toward math, science, and design. That interest led me to the University of Miami on a Presidential Scholarship, where I set out to design next-generation fighter aircraft—an ambition inspired by a lifelong admiration for the Blue Angels. As with many journeys, mine evolved in unexpected ways.

After my first year, I transferred to the University of Southern California’s Marshall School of Business following several months working in mobile app development and quality assurance during my transition across the country. During the remainder of my undergraduate studies, I focused on developing practical technical skills in front-end web development and video game design. I graduated with a Bachelor of Science in Business Administration and a minor in Archaeology. With my graduation ceremony taking place in my kitchen during the COVID-19 pandemic, I—like many others—faced uncertainty about what would come next.

Rather than accepting a remote role in quality assurance, I chose to treat the crisis as an opportunity. On the advice of a USC advisor, I enrolled concurrently in four community colleges—made possible by fully remote instruction during COVID-19. Through sustained effort, often studying twelve or more hours per day, I completed the equivalent of a bachelor’s degree in mechanical engineering in two years. In 2022, I was fortunately accepted into USC’s Master of Science in Mechanical Engineering program.

Through in-depth conversations with mentors, I came to understand that traditional mechanical engineering pathways often funnel graduates toward either defense or petroleum. At that moment, I made a vow never to design with the intent of causing harm. Seeking a more impact-driven direction, I petitioned the Dean of Viterbi and successfully transferred my admission into the Green Technologies program—an engineering master’s degree focused on sustainability.

Since then, my work has been guided by a singular focus: addressing the world’s most pressing challenges. Through experience in both engineering and sustainability, I have come to believe that the most consequential problems facing humanity are social in nature. Today, I work in advocacy and—most importantly—on helping address the growing divides in society by fostering understanding, collaboration, and durable human connection.

Writing & Commentary

This space is where I share perspectives on technology-driven problem solving and the human dimensions of engineering. I reflect on advocacy, dialogue, and building tools that strengthen human connection, drawing from hands-on work, research, and real-world leadership experience
