It's time to dust off the cobwebs and get those cogs turning in your noggin 'cause Ready Steady Learn is back for 2025 thanks to Waipapa Taumata Rau - The University of Auckland.

Ebrahimi's work involves building computer models of lungs tailor-made to patients' own that can predict how blood flow and pressure will change following surgical intervention. Whakarongo mai nei!
