Sebastian Martin grew up in a small town in Germany with a rich tradition in toy making, and he attributes his interest in learning through experimentation and play to this early experience. Before coming to the United States, he studied earthquakes in the Chilean Andes, satellite imaging in the boreal forests of Ontario, and physics and math in Erlangen, Germany. He earned a PhD in geophysics from the University of Potsdam. Throughout his studies, he retained a playful approach to science and research, and he developed interactive exhibits at Phenomenta, a science center dedicated to inquiry and direct contact with phenomena. In 2005 he joined the Exploratorium, where he found a happy symbiosis among science teaching, playing, and making things. An exhibit developer at the museum, Sebastian also enjoys teaching physics and interactive design at the University of California, Berkeley, and Stanford University.
