Born in Providence, Rhode Island, Siner began her studies at the Art Students League of New York in 1968, graduated from Boston University (BFA) and American University (MFA) and has lived for extended periods in France, China and Italy. Her work has been exhibited in galleries and museums for over 30 years and is in hundreds of collections around the world.
Siner's work is classically derived yet absolutely contemporary. While freely handled and gestural, her paintings have a strong sense of underlying structure. She works exclusively from life, one of a small number of contemporary artists using direct visual perception to translate the human experience into material form. Her influences from Chinese painting are evident in free and responsive brushwork. A master of paint, she is known for evocative portraits, unexpected still-life arrangements, and a sparkling play of light and shadow emphasizing the momentary nature of vision and time.
Siner is also a devoted teacher who has influenced a generation of painters. She has been on the faculty of L'Institut d’Universités Américaines and Lacoste School of Art in France, a visiting professor at Xiamen University in China, Artist in Residence at the Savannah College of Art and Design, Dean of Faculty at the Washington Studio School and teaches workshops and seminars. She is a frequent guest artist and public speaker appreciated for her revealing lectures on the internal workings of painting
