She obtained her PhD at the University of Minnesota investigating spectroscopic changes in eta Carinae, one of the most massive stars in our Galaxy. Her scientific interests lie in the different phases of evolved very massive stars.

André Mueller is an ESO fellow with duties in Paranal Observatory since September 2012. He carried out his PhD thesis at the Max Planck Institute for Astronomy in Heidelberg and received his PhD in 2012 at the University of Heidelberg (Germany) investigating the properties of Herbig Ae/Be stars. His scientific interest lie in young stellar objects such as Herbig Ae/Be and T Tauri stars. Besides searching for extrasolar planets and (sub-)stellar companions around these stars he determines their stellar parameters and characterize their activity behaviour (photospheric phenomena, accretion) using mainly optical and NIR high-resolution spectroscopy. He is also interested in disk studies using NIR and MIR interferometric data.

Koraljka Muzic is an ESO Fellow with duties at the Paranal Observatory. She obtained her PhD from the University of Cologne in collaboration with the Max-Planck Institute for Radioastronomy in Bonn (Germany) in 2008. Before joining ESO in May 2012, she worked as a postdoctoral researcher at the University of Cologne, Germany and the University of Toronto, Canada. Her research interests include formation and evolution of low-mass stars and brown dwarfs, the shape and the origin of the IMF, and the studies of the central parsecs of the Milky Way.

Fabien Patru is an ESO fellow with duties in Paranal Observatory, mainly on the VLTI. He completed his PhD at the Observatoire de la Cote d'Azur (OCA, Grasse, France), and spent a year at the Laboratoire d'Astrophysique de Grenoble (LAOG, Grenoble, France) before joining ESO in 2009. His main research interest is focussed on stellar physics by using interferometry techniques. He is involved on AMBER programs to study the stellar surface structures of red giants and the circumstellar environment of miras and cepheids. He also studies the direct imaging capabilities of future large arrays of telescopes using the hypertelescope concept.

Daniela Barria

Daniela Barria is a PhD student at ESO since March 2011, working under the supervision of Linda Schmidtobreick. She graduated in 2006 from the Universidad Catolica del Norte in Antofagasta (Chile) working with Nikolaus Vogt about the changes in superhumps periods for SU UMa dwarf novae. She is doing her PhD at Universidad de Concepcion with Ronald Mennickent as advisor studying the photometric long variability in an interesting type of close binaries named Double Periodic Variables. She is interested in Variable Stars, Close Binaries, and CVs.

Bruno Dias is a PhD student at ESO-Chile since October 2012, under the supervision of Dr. Ivo Saviane. Bachelor in Physics (2007) and Master in Astrophysics (2010) by the Universidade de Sao Paulo, Brazil, he is undertaking his PhD in the same institute, but he is working one year at ESO. His advisor in Brazil is Dr. Beatriz Barbuy, and his Master's dissertation was focused on globular clusters in the Small Magellanic Clouds using both integrated spectroscopy, and photometry. Bruno's PhD thesis concerns the globular cluster system of the Milky Way, providing an alpha-enhancement and metallicities catalog for about 60 clusters using FORS2/VLT spectra of their red giant stars. His main topics of interest are: globular clusters (GC systems, multiple populations GCs, relations between GCs and dwarf galaxies), and stellar populations (halo and bulge of the Milky Way, and interaction between the Milky Way and nearby galaxies).

Jens-Kristian Krogager

Jens-Kristian Krogager finished his Bachelor's degree in physics and astronomy from Copenhagen University in 2009, about modeling detection of exoplanets in microlensing events. In 2010 he started a combined master and PhD-programme at the Dark Cosmology Centre (Copenhagen University) supervised by Prof. Johan Fynbo. His PhD work focuses on galaxy formation by studying absorption line systems seen towards high-redshift quasars, and how these link to the population of galaxies we see in emission. He started at ESO in December 2012 with Cédric Ledoux as his supervisor.

Stefan Lieder

Stefan Lieder is a PhD student at ESO/Santiago since March 2011. After he obtained a diploma in Mechanical Engineering in 2004, he studied Physics at the universities of Karlsruhe and Heidelberg in Germany where he graduated in 2010. His diploma thesis was about dwarf galaxies in the Virgo cluster core. Since 2010 Stefan is working on his PhD thesis about star clusters and dwarf galaxies in groups and clusters of galaxies. While his supervisor at his home university in Heidelberg is Dr. Thorsten Lisker, at ESO he is under the supervision of Dr. Steffen Mieske and Dr. Ruben Sanchez Janssen and Dr. Michael Hilker (Garching). Stefan's main interests are galaxy formation and evolution as well as the linking between dwarf galaxies and star clusters.
