ETH Zürich
Professor

Thomas H. Zurbuchen, known in the space community as Dr. Z, is a Swiss-American astrophysicist, leader, and innovator. 

Since June 2023, he is the leader of the ETH Space initiative. His stated goals are to build the world's best Master’s programme in space science and technology, improve on the entrepreneurship programme to enable more Swiss startups, and to assist space sciences. The Master's programme took on its first students in September 2024.

Prior, he was the longest continually serving Head of Science at NASA from October 2016 through 2022, the leading program worldwide for doing science in and from space. During this time, he drove all aspects of leadership in space science, leading 130 missions with 37 launches. His achievements include bringing the international James Webb Telescope to launch, overseeing two Mars landings - the Perseverance rover and the first controlled flight away from the Earth with the Ingenuity helicopter - and developing the Parker Solar Probe, a mission to touch the Sun. He also conceived and led the Earth System Observatory, an advanced multi-platform observatory that creates a 3D holistic view of the Earth, from bedrock to atmosphere, and oversaw humanity’s first successful attempt at moving a celestial object, using a spacecraft impact.

Dr. Zurbuchen was born in Switzerland in 1968, became the first college graduate in his family, studied physics at the University of Bern with a minor in mathematics, and was awarded his PhD in 1996 with a thesis entitled “Turbulence in the interplanetary medium and its implications on the dynamics of minor ions”.
