Natalie Jeremijenko (born 1966) is an artist and engineer whose background includes studies in biochemistry, physics, neuroscience and precision engineering. She is an active member of the net.art movement, and her work primarily explores the interface between society, the environment and technology. She has alternatively described her work as "X Design" (short for experimental design) and herself as a "thingker", a combination of thing-maker and thinker. She is currently an associate professor at New York University in the Visual Art Department, and has affiliated faculty appointments in the school's Computer Science and Environmental Studies. She directs the Environmental Health Clinic at New York University, which is modeled on the health clinic model, but offers patients prescriptions not for pharmaceuticals but for art, design and participatory projects.
