In 2004, she gained a BA in physics from the University of Oxford, and in 2005, an MSc in Structural Engineering from Imperial College London.

Agrawal attributes her enthusiasm for engineering to her love of making (and breaking) things, cultivated by playing with Lego as a child.

She spent six years working on the tallest building in Western Europe, the Shard, designing the foundations and the iconic spire.

[7] The spire required modular construction that could be built and tested off-site, enabling quick and safe assembly at height in central London.

[20] She was a founding member of the Your Life Campaign, designed to change school children's perception of science and engineering backed by the Department of Business, Innovation and Skills.

[21] In 2014, she was part of Marks and Spencer's Leading Ladies campaign, alongside Annie Lennox, Emma Thompson and Rita Ora.

Since 2017, she has appeared as a judge on the Channel 4 reality programme Lego Masters[26] and as a structural engineer expert on Mysteries of the Abandoned.
