Tim Robishaw is currently a Research Officer (Astronomer) working in the Radio Astronomy Program of NRC-Herzberg at the Dominion Radio Astrophysical Observatory (DRAO) in Penticton, BC, Canada.
Tim is actively studying the role of magnetic fields in the structure and physics of the interstellar medium, both in our own Milky Way Galaxy and in other galaxies far, far away. He employs the spectropolarimetric tools of Zeeman splitting and Faraday rotation to detect magnetic fields via radio emission from a diverse set of astrophysical environments. These include such objects as molecular and atomic gas clouds in the Milky Way, galaxies undergoing intense high-mass star formation, and distant galaxies whose interstellar matter has been ionized. Tim specializes in single-dish radio astronomy and currently uses the 26-m John A. Galt Telescope at the DRAO, the 64-m Parkes Radio Telescope, the 100-m Robert C. Byrd Green Bank Telescope, and the 305-m William E. Gordon Arecibo Telescope. Tim also uses the multi-element Karl G. Jansky Very Large Array and the Very Long Baseline Array in order to study the magnetic fields in other galaxies at high spatial resolution.
Tim received his Ph.D. degree from the University of California at Berkeley in 2008. He was a Postdoctoral Fellow in Radio Polarimetry at the University of Sydney then an Australian Research Council Super Science Fellow from 2008-2011, and a Covington Fellow at DRAO from 2011-2013. Tim is currently upgrading the 26-m John A. Galt Telescope for a large-scale survey of Zeeman splitting in the 21-cm emission from clouds of neutral atomic hydrogen in the Milky Way.
