Prof. Mark Gieles


Mark Gieles received his PhD degree at Utrecht University in the Netherlands in 2006. He then moved to the European Southern Observatory (ESO) in Chile as a research fellow and support astronomer on the Very Large Telescope (VLT) at Cerro Paranal in the Atacama desert. As part of this fellowship he spent 3 months as a visiting scientist at the School of Mathematics of the University of Edinburgh to work with Douglas Heggie. In 2009 he obtained a University Research Fellowship (URF) of the Royal Society which he took up at the Institute of Astronomy of the University of Cambridge. In January 2013 he started as the first chair in astrophysics in the Department of Physics of the University of Surrey and he was the head of group until 2018. He is currently PI of an ERC Starting Grant project to understand the origin of globular clusters and their connection to the formation of the Milky Way (CLUSTERS: "Galaxy evolution through the eyes of globular clusters").
