Biography

I am a mechanical engineer and educator with a passion for helping students master complex STEM topics. I graduated from UC San Diego with my Bachelor’s degree in 2023 and completed my Master’s in Mechanical Engineering (specializing in Optics and Materials) in 2025.

My teaching philosophy is built on the belief that confidence comes from competence. Since 2017, I have tutored students in Physics, Chemistry, and Math levels up to Calculus, alongside humanities subjects like English, Spanish, and Korean. Having worked in Research & Design at companies such as Illumina and ASML, I bring a practical, industry focused perspective to my sessions. I love mentoring aspiring engineers and showing them how the math they learn today applies to the technology of tomorrow.

I strive to create a supportive environment where students feel safe tackling difficult problems. When I’m not in the classroom or the lab, I enjoy unwinding with hot yoga, sipping a strong coffee, and walking my dog, Puddles.
