Sieanele Ponce (she/her), also known as ecdysis.exp, is a Filipina installation artist and experience designer based in the Bay Area. She builds immersive, multisensory environments using projection, light, textiles, and sensor-responsive elements — site-specific installations that explore transformation, perception, and collective ritual. Her work draws on her background in psychological and brain sciences, treating environments as active participants in how people feel, connect, and make meaning. She has created installations and experiences for Gray Area, Parameter Festival, and Bituin Studio, and her work was featured in Gray Area's Local Memory Showcase (2026) and Earthseed Remnants at ARTogether (2026). Working primarily with MadMapper, she is especially interested in making projection mapping accessible as a tool for atmosphere, storytelling, and presence. She holds a B.S. in Psychological & Brain Sciences from UC Santa Barbara.
