Sofia Randich Director of Research Sofia is a Co-PI of the Gaia-ESO survey, and therefore plays a key role in the organisation and running of the survey. She is also responsible for the open cluster observations within Gaia-ESO, from initial selection to final monitoring. Research Interests: Research interests: Sofia's scientific activities focus on a variety of topics, including cluster formation and evolution, the evolution of stellar properties, the understanding of internal mixing in stars, the formation and evolution of the MW thin disc, planet searches in clusters. Sofia is member of the Gaia Science Team, and of the science teams of Weave and MOONS. She is also member of the steering committee of the TESS working group on star clusters.
	Elena Franciosini Researcher Elena is one of the Survey builders, and the Arcetri node representative for WG12. She is part of the Arcetri UVES data reduction team, together with Germano and Lorenzo M.; in particular, she is in charge of the combination of all the spectra obtained for each star into a single co-added spectrum, and of the derivation of the final radial and rotational velocities. She is also involved in the derivation of lithium abundances for WG12 (analysis of pre-main sequence stars), WG10 and WG11 (analysis of Giraffe and UVES FGK stars), and in the derivation of temperatures using line-depth ratios for the joint GES-COROT project. Research Interests: During her career, Elena has been involved in the study of stellar activity both in single stars and in open clusters at radio and X-ray wavelengths. In the last few years, her research has been mostly dedicated to the study of lithium abundances in young and old open clusters.
	Laura Magrini Researcher Laura is the coordinator of the Node of Spectral analysis EPInArBo (ESO, Padova, Indiana, Arcetri, Bologna) that analyses both WG11 and WG10 spectra. She is also a member of WG15 (homogenisation Working Group and a member of WG4. Research Interests: In the last few years, Laura has been working on several projects concerning the composition of Galactic open clusters and its implication on the process of formation and evolution of the Milky Way. Specifically, she has been working on the abundances of neutron-capture elements in the different Galactic populations, and the ages of Open Clusters through isochrone fitting.
	Lorenzo Morbidelli Researcher After the approval of the Gaia-ESO Survey (2011) Lorenzo's task (in collaboration with G. G. Sacco and E. Franciosini) has been to implement the ESO pipeline on the local system in Arcetri. A number of problems had been identified and solved in this phase. Since the beginning of the observations Lorenzo's task is to process the raw data taken by the UVES spectrograph in order to produce wavelength-calibrated spectra and perform a first-look quality control. To this purpose a system of scripts has been prepared. To comply with changes in instrumental and calibration setup and to solve pipeline problems the scripts need to be regularly updated and modified. The pipeline itself had to be corrected in many ways. This work has been performed in collaboration with the ESO software team. Research Interests: In addition to Lorenzo's work within the Gaia-ESO survey, he has also been processing and reducing ESO historical data taken with UVES spectrograph starting with its commissioning (around the year 2003). This archive is at present comparable in size with the main Gaia-ESO Survey.
	Elena Pancino Researcher Elena has participated in the preparation phases of the survey since the end of 2010, with massive tests of abundance analysis on simulated spectra, to identify the best observation strategy of field stars. She coordinated the Bologna abundance analysis node until 2014. She leads the standard and calibrations working group. Research Interests: Apart from her interest in resolved stellar populations, especially open and globular clusters and dwarf galaxies in the local group, Elena is an expert in the abundance analysis of high resolution stellar spectra. She also participates to the Gaia Mission DPAC (Data Processing and Analysis Consortium), leading the group that is preparing the large grid of spectrophotometric standard stars for the absolute flux calibration of Gaia photometry and spectra since 2006.
	Germano Sacco Researcher Germano has been involved in the Gaia-ESO Survey since the beginning of the observations at the end of the 2011. Together with Lorenzo Morbidelli and Elena Franciosini, he is involved in the initial data processing of all data taken with the UVES spectrograph, which is entirely carried out at Arcetri. Specifically, his duties include the quality control of the spectra, the derivation of radial velocities and projected rotational velocities, and the management of the internal releases of spectra. He is also a member of the working group in charge of the analysis of Pre-main sequence stars and a builder of the Survey. Research Interests: During his career, Germano has studied several open issues in the field of star formation using both multi-wavelength observations and numerical modeling. In the last years he mostly focused in studies of cluster dynamics with the Gaia-ESO Survey. In the future, he will devote his efforts to combining Gaia-ESO and Gaia data to move his analysis into a multi-dimensional domain.
