I'm Dashiani Navanayagamdeh.
But before we start a what do these three inventions, the washing machine, windscreen wipers and Kevlar, the material used to make bulletproof vests, all have in common?
Well, they were all designed by women.
Women have often played a crucial role in pioneering research, from computer sciences to biotechnology and engineering, even though their work has often been overlooked.
But not today, because for the next half an hour, we'll be talking about women inventors and innovators with my guests.

She's best known for her work on the shard, the tallest building in the UK.
And she recently published a book, nuts and bolts, in which she explores the history of seven tiny but fundamental inventions that changed the world.
Roma, welcome.
