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.
Dr Ivan Cabrera-Ziri started his new position as Gliese Fellow 2021 at the Astronomisches Rechen-Institut (ARI). Dr. Ivan Cabrera-Ziri carried out his PhD between Liverpool John Moores University and the European Southern Observatory in Garching. In 2017 his thesis work got awarded the prize for the best thesis of the Faculty of Engineering and Technology of Liverpool John Moores University, and was the runner up for the Royal Astronomical Society's Michael Penston Thesis Prize for the best doctoral thesis in astronomy. Before arriving to the ZAH he was a Hubble Fellow at The Center for Astrophysics at Harvard University.
His main scientific interests are the formation and evolution of star clusters and their chemical properties, in particular how to use the properties of globular clusters to trace the build up of galaxies.
Dr. Cabrera-Ziri will spend his fellowship at ZAH/ARI which started on August 1, 2021.
Dr Giulia Despali studied and did her PhD at the University of Padova. The focus of her thesis was the evolution of dark matter halo properties in cosmological simulations and she graduated in 2015. Dr Despali spent 2015 as a visiting researcher at the Laboratoire d’Astrophysique de Marseille (LAM), before moving to Munich and MPA in 2016. Her research focuses on the nature of dark matter and on the connection between computational astrophysics and observational data. She explores the effect of alternative dark matter models, such as warm and self-interacting dark matter on the properties of galaxies and haloes, and compares these with predictions from the standard CDM scenario. In particular, her goal is to use and create state-of-the-art hydrodynamical simulations to study the properties of galaxies at small scales and derive theoretical predictions for the comparison with different observables, such as for example substructure gravitational lensing, the number of satellite or the properties of lens galaxies. Observations from ALMA, JWST, VLBI or E-ELT will provide higher spatial resolution and thus exploring the properties of the matter distribution at small scales with simulations, combining baryons and dark matter, is essential to interpret new data.
Dr. Despali will spend her fellowship at ZAH/ITA and is going to start on Dec. 1, 2020.

Melanie Habouzit carried out her PhD-studies on the Formation of supermassive black holes in Paris at the Institut d’Astrophysique de Paris (IAP) which she finished in 2016. Subsequently, she moved to New York and became a Flatiron postdoctral fellow at the Center for Computational Astrophysics.
Her research interests lie in the field of galaxy formation and evolution. Dr. Habouzit is particularly interested in understanding how these supermassive black holes form in the very early Universe, and how they grow to produce the variety of black holes that we observe today. Her research also focuses on the connections between the central black holes and their host galaxies, and their co-evolution through cosmic times.
To advance our understanding of the early Universe, she performs large-scale cosmological simulations with her model for the formation of supermassive black holes. These simulations are powerful tools to understand the formation of supermassive black holes, their evolution, their number density, the galaxy black hole occupation fraction. She is actively working on using these simulations and other state-of-the-art large-scale simulations (IllustrisTNG, Horizon-AGN) to prepare upcoming missions such as e.g., JWST, WFIRST, LISA, and Athena.
Dr. Habouzit will spend the first part of her fellowship at MPIA as MPIA/Gliese Fellow and the second part at ZAH/LSW as Gliese/MPIA-Fellow. Her fellowship in Heidelberg is going to start on Nov. 1, 2019.

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.

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).

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.
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 a Postdoctoral Research Fellow 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.
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.
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.
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.
