[3][9] Hayat Sindi is a visiting scholar at Harvard University;[14][15] as such, she travels often between Jeddah, Saudi Arabia and Boston and Cambridge, Massachusetts.

[16] Along with her scientific activities, Sindi participated in numerous events aimed at raising the awareness of science among women and girls, particularly in Saudi Arabia and the Muslim World in general.

Hayat Sindi was a major influence in starting three companies, either as cofounder or founder: Diagnostics for All (DFA),[17][18] which aims to create low-cost devices that can be used in developing countries to diagnose diseases; Sonoptix; and i2 (the Institute for Imagination and Ingenuity),[19] which promotes science education and innovation among younger generations.
