Hi, I'm Meha Agrawal
A recent IB graduate from Sydney who builds things that move. I work on physical prototypes including maglev trains, submarines and architectural models. I also publish research on the systems those machines run inside. Most of my projects exist because I wanted to find out whether something I'd calculated would hold up on a bench.

About me
My journey
I've lived across four countries: South Korea, Hong Kong, Singapore and Australia. I moved to Sydney mid-Year 9, five weeks before semester exams, having just changed countries and missed an entire term of content. I wasn't eligible for year-level awards that semester. By Year 10 I placed in the top three of my cohort and came first in Design and Technology across the year group.
Alongside building, I write. I've published two papers in the National High School Journal of Science, written an illustrated children's book teaching physics through the Bhagavad Gita, and I edit my school's magazine.
