After several years of work as professor in secondary schools in Italy, Elisabetta Caffau obtained a PhD in observational astronomy from Paris Observatory in 2009. After a one year post-doctoral position in Paris Observatory, E. Caffau obtained the Gliese fellowship Grant in 2010. E. Caffau has developed a method to obtain high precision abundances of the elements from 3D hydrodynamical computations. With the infrared spectrograph CRIRES at ESO/VLT, she measured the phosphorus abundance of twenty cool stars in the Galactic disk for the first time. In 2013 she was honored with the 2013 MERAC Prizes for the Best Early Career Researcher in Observational Astronomy for the discovery of a very primitive low-mass star in our Galaxy.
Gliese Fellowship Programm
The Gliese Postdoctoral Fellowship Program of the Zentrum für Astronomie der Universität Heidelberg (ZAH) is named in honor of Wilhelm Gliese (1915 - 1993) and his pioneering astrometric studies of stars in the solar neighborhood.
The Gliese Postdoctoral Fellowship provides a competitive stipend and a generous research budget for up to three years (initially awarded for two years) to outstanding postdoctoral researchers in any area of astronomy or astrophysics in which scientists at ZAH are active.
The goal of the Gliese Fellowship is to offer scientists typically within a few years after receipt of their PhD the best possible opportunities to develop their talents within a fruitful and inspiring scientific environment. Gliese Fellows enjoy great freedom in their research activities.
Gliese Fellow 2018: Dr. Fabian Schneider
Fabian Schneider studied Astrophysics at the University of Bonn and received his MSc in 2011. Also in Bonn he carried out his PhD-studies which he finished in 2014. Subsequently, he took up his first postdoc position at the Argelander Institute for Astronomy at the University of Bonn. In 2015 he moved to Christ Church College in Oxford (UK) and became Hintze Research Fellow at the Department of Physics of the University of Oxford.
In his work Dr. Schneider studies the evolution and final fates of stars to understand their role in the cosmos and how they transformed the pristine Universe into the one we live in today. His work is mostly of theoretical nature and he makes heavy use of stellar evolution codes, population synthesis models and advanced Bayesian statistical methods.
Fabian Schneider actively participates in large international collaborations (e.g. the VLT-FLAMES Tarantula Survey and the B-fields in OB stars project) where he investigated fundamental questions of stellar evolution. For example, they showed that the evolution of massive stars is dominated by binary stars that exchange mass with their companions or even merge. He further lead the research that discovered that the gigantic 30 Doradus starburst in the Large Magellanic Cloud contains many more massive stars than expected—a discovery that has far-reaching consequences, in particular for the evolution of galaxies and the reionisation of the Universe.

Gliese Fellow 2017: Dr. Robert Harris
Robert Harris studied Astrophysics at the University of St. Andrews before changing field to Astronomical Instrumentation for his PhD at Durham University, which he received in 2015. Due to his promising research in the field of astrophotonics, in particular photonic reformatters he was awarded a six month STFC STEP award. This enabled him to conduct further tests, improving the performance of the devices. During this time he was awarded a Carl-Zeiss Stiftung to work at the Landessternwarte at the University of Heidelberg. Here his main scientific interests remain in the field of astronomical instrumentation, particularly photonic reformatting technology, but has now expanded to also include new manufacturing methods and control methods (see also THIS press release).

Gliese Fellow 2016: Dr. Markus Kromer
Markus Kromer studied Physics at the University of Tübingen and received his PhD from the Technical University of Munich in 2009. In the following years, he worked as a postdoctoral fellow at the Max Planck Institute for Astrophysics in Garching. In 2011, he was awarded the Otto Hahn Medal by the Max Planck Society, recognizing outstanding scientific achievements during his PhD. In 2013, Markus obtained an Oskar Klein Fellowship from Stockholm University and joined their Department of Astronomy. Markus' research revolves around the application and further development of computational radiative transfer methods to link astronomical observations and theoretical astrophysical models. He has developed a massively-parallel computer program to simulate the observable display of the powerful explosions in which stars end their lives. These so called supernova explosions can outshine a whole galaxy with a billion of stars for a short period of time. At the ZAH Markus will lead research projects to investigate the nature of Type Ia supernovae – an observational subclass of supernovae which are important beacons to measure distances in the Universe. In close collaboration with scientists from the PSO group at the HITS, Markus will use theoretical explosion models to shed light on the progenitors and physical mechanisms of these luminous explosions.
Gliese Fellow 2015: Dr. Diederik Kruijssen
Dr. Kruijssen received his PhD from Utrecht University in 2011, after carrying out his research as an NWO Toptalent Fellow at the universities of Utrecht, Leiden and Cambridge. From 2011 to 2015, he worked as PhD at the Max-Planck Institut für Astrophysik in Garching. In 2013, he received the Christiaan Huygens Prize of the Dutch Royal Academy of Sciences for the best Dutch PhD thesis in Astronomy & Space Sciences during the four years 2009-2012. His research interests range from the formation of stars, planets, and globular clusters to the large-scale assembly of stellar mass and galaxy formation. At ZAH Dr. Kruijssen studies the cloud-scale physics of star formation and feedback, covering the formation of globular clusters in the early Universe to galactic star formation at the present day. For this purpose, he will apply novel observational and numerical methods that enable an unprecedented view on the small-scale baryonic physics that drive the large-scale evolution of galaxies.
Gliese Fellow 2014: Dr. Yiannis Tsapras
Dr. Tsapras' primary research interests lie in the field of exoplanet science, where he uses the techniques of microlensing and transits to search for planets orbiting distant stars. He is founding member of the RoboNet project which uses the LCOGT telescope network to detect exo-planets by microlensing.
Before he came to ZAH he sated his scientific curiosity working for the LCOGT institute (2007-2014). During the 2012-2014 academic period he was also a Teaching Fellow at the School of Physics and Astronomy, Queen Mary University where he taught Physics for the Science and Engineering Foundation Programme and a MSc course on Extrasolar Planets and Astrophysical Discs. Prior to that, he held a research position at the ARI in Liverpool. Dr. Tsapras has received his PhD from the University of Saint Andrews in 2003.
Gliese Fellow 2013: Dr. Davide Gandolfi
Dr. Gandolfi got his PhD in physics/astronomy from the University of Catania in 2007. His first two years as a postdoc brought him to the Thüringer Landessternwarte in Tautenburg. He also worked as a Research Fellow at the European Space Agency from 2010 to 2012 and as a Marie Curie AstroFIt fellow at the INAF-Catania Astrophysical Observatory in 2013. His main scientific interests focus on the search and characterization of transiting exoplanets within the context of the CoRoT and Kepler space missions, as well as on the study of the mechanisms leading to the formation of the so-called hot Jupiters.
Gliese Fellow 2012: Dr. Simon Murphy
Dr. Simon Murphy received his Ph.D. in July 2012 from the Australian National University's (ANU) Mount Stromlo Observatory. His thesis examined two associations of young stars in the deep southern sky, Eta and Epsilon Chamaeleontis as ideal targets for better understanding the evolution of young stars and their circumstellar disks. Simon Murphy also has a keen interest in the scientific exploitation of the Virtual Observatory and is involved with the SkyMapper survey telescope at Siding Spring Observatory in Australia. During his time at ZAH he continued to work on refining techniques for selecting and characterising young stars from large photometric and proper motion surveys. He also worked closely with the German Astrophysical Virtual Observatory (GAVO) group hosted at ARI to develop new tools for VO-enabled science.
