In 1998, he came back to Brussels, obtaining a permanent position as Senior Researcher at the Royal Observatory of Belgium. There, he organised the first international workshop on Astro-tomography. As he is very keen to share science with society, he also graduated from the 1st promotion of “Journalist & Scientist” at the Ecole Supérieure de Journalisme de Lille, France. He has had experience in journalism and editing, and in 2003, joined ESO as Astronomer and Press Officer, dealing with communication about all telescopes and projects of ESO. He was member of the steering committee of the very successful Venus Transit 2004 Programme and of the EIRO forum Science on Stage festivals, and coordinator of the IYA 2009 Gigagalaxy Zoom project.

Ivo Saviane
(LSO)

Ivo Saviane has been in its position as La Silla Site Manager officially since October 2013. However, his history at ESO commenced about 12 years ago.

Right after that he became an Operations Staff Astronomer at La Silla, starting a steady career closely related with the site. Among other positions at La Silla, he has been at various times Instrument Scientist of FEROS, TIMMI2, EMMI, and EFOSC2, and he became Head of Science Operations in 2008. After moving to Paranal as an Operations Staff Astronomer, he became Instrument Scientist of FORS2 and later KMOS.
Ivo obtained his Masters degree in Astronomy from the University of Padova in 1991 with work based on colour-magnitude diagrams of three Galactic globular clusters, under the supervision of Prof. M. Capaccioli and Dr. G. Piotto. He received his Ph.D. in Astronomy from the same university in 1997.

Frederic Schuller
(APEX)

 

Frederic Schuller has joined ESO in August 2011, as head of science operations at APEX. He received his PhD from the Institut d'Astrophysique de Paris in 2002. His PhD work was focussed on the analysis of recent high-mass star formation in our Galaxy based on the ISOGAL infrared survey of the Galactic plane. Then, he moved to the Max-Planck-Insitut fuer Radioastronomie in Bonn, where he got involved in the very early stages of the APEX project. In particular, he played a crucial role in the development of the BoA (Bolometer array data Analysis) software, and in the commissioning of the Large APEX Bolometer Camera (LABOCA). Frederic is also the PI of the ATLASGAL (APEX Telescope Large Area Survey of the Galaxy) project, that produced the so-far largest map of the Galactic plane at sub-millimeter wavelength, covering more than 400 square degrees at 870 micron.

Fernando Selman
(PAO/SCV)

Fernando Selman's current observational research interests include studies of the nature of the stellar IMF in several systems, and the dynamics and binary content in 30 Doradus using SINFONI. He recently found, together with his collaborators, that the IMF of the field stellar population in 30 Doradus is, within errors, consistent with a Salpeter law. In a recent project on the Arches cluster we reached a similar conclusion thus giving strong support to the hypothesis of universality of the IMF.  On a larger scale he is interested in the intergalactic light in clusters of galaxies. In the course of this research discovered with his collaborators an interesting S-shaped gravitational arc, an image of which can be seen in his personal web page. On a theoretical side he is interested in the dynamics of gravitational systems with particular attention to the phenomenon of dynamical friction. He is currently involved in an n-body simulation study of the stability of star clusters as a function of the mass of its heaviest star.
As an observatory astronomer, he has been instrument scientist for the Wide Field Imager (WFI) at La Silla, and he is currently at Paranal as instrument scientist for HAWK-I, VIMOS, and OmegaCam. Part of his technical work include the development of techniques that permit the determination of zero point correction maps in imaging instruments.
He started his career as a physics student at the School of Engineering of Universidad de Chile subsequently obtaining his PhD at Caltech in 2004. During his strongly acausal career he was Fulbright Travel fellow, Carnegie-Chile Fellow, and Beatrice Watson Parrent postdoctoral fellow.

Rodrigo Parra
(APEX/SCV)

Rodrigo Parra is Support Astronomer at the APEX project. He obtained an Electrical Engineering Degree at Universidad Tecnica Federico Santa Maria and a MSc in (Microwave) Digital Communications Systems at Chalmers University in Sweden. Subsequently, he received a PhD in Radio Astronomy from the Onsala Space Observatory in 2007. In addition to his expertise in single dish mm-astronomy, He has specialized in continuum and spectral line cm and mm wave interferometric techniques particularly VLBI. He is deeply interested in the study of possible evolutionary connections between AGN and starburst activity. One of the guiding questions of his research is whether or not the 100 parsec regions of starburst activity seen in external galaxies are scaled up versions of galactic star forming regions. If not, what makes them different?  He has studied star formation and AGN activity using cm and mm wavelength VLBI observations of large samples of galaxies as well as deep cm and mm wavelength interferometry of single objects. He also actively collaborates in several research projects whose topics include Interstellar Masers (OH megamaser galaxies and Hydrogen Masers), dense molecular gas in star-forming regions and theoretical models of propagation of radiation in clumpy media.
