Nieves was born in Madrid (Spain) in 1960. With a degree in Art History, she has trained, among others, with Concha Jeréz, Isidoro Valcarcel Medina, Frances Torres and Antoni Muntadas.

She began her career in Action Art and Performance Art at the end of the eighties and since then she has participated in festivals and meetings mainly in Europe but also in Canada, Ecuador, Argentina, Uruguay and Japan.

“My performances are always related to the space in which they take place, I like to explore and exploit the physical and/or symbolic possibilities of the place where I work; and that space helps me to shape the formal structure of my proposals. It is possible that a material, a situation or an obsession triggers a process, and from that first approximation I build the performance from a formal perspective analyzing time, space, my presence, the audience, the material…”

Her plastic work is always nourished by her own performances or has as its starting point in a "performative process" in which the body, space and time are present. In most of her pieces she uses photography in relation to her body, a body that she feels and shows fragmented, in dialogue with elements and materials that she has used and modified in her live works.
