She studied at the Ecole Nationale Superieure de Création Industrielle (ENSCI) in Paris, graduating in 1993.
She is known for creating versatile designs, such as lamps that can be extended like accordions and a suitcase prototype for the manufacturer VIA that can replace a hotel wardrobe by adjusting its size.
Many of Inga Sempé's lamps feature fan-like lampshades that create diverse light and shadow effects.
The Plissé pendant lamp, produced by Luceplan, is designed with pleated material that can be unfolded like an accordion.
