Hsieh is a graduate of Parson Fine Art MFA program in New York. He explores various materials and media to further develop and diversify his art practice. Hsieh is best known for his soft sculptures made from vibrant color felt and poly-fill. His work transforms soft fabrics into solid sculptures with intriguingly unique appearances. Hsieh explores his dreams and memories that depict the complexities of the subconscious mind through a combination of color, textile, culture and symbolism. His works have been widely exhibited and are in the permanent collection at White Rabbit Gallery, one of the biggest contemporary art institutions in Australia.
