The LESIA (Laboratory of Space Studies and Instrumentation in Astrophysics) is one of the five Scientific Departments of the Observatory of Paris. It is also a CNRS Laboratory (mixed Reasearh Unit of CNRS – UMR 8109). LESIA is associated with the University Pierre Pierre et Marie Curie - Paris 6 (UFR de Physique 925, Institut de la Vision) and with the University Paris-Diderot-Paris 7 (UFR de Physique et UFR Sciences de la Terre, de l’Environnement et des Planètes - STEP).
LESIA is one of the largest French laboratories of research in astrophysics (approximately 12% of the discipline). In April 2013, the laboratory counted 238 staff including 133 permanent.
The permanent staff is composed of:
69 Researchers/Scientists of CNRS, the CNAP or members of Universities;
64 Engineers/Technicians/Administrators of CNRS or members of Universities.
A management team supervises the laboratory :
The organisation of the personnel in poles allows teams coordination and interface with the directors:
Five scientific poles :
Three technical poles:
The responsibility for Continuing Education – an important part of the Human Resources management – has been delegated to Jérôme Parisot.
Emmanuel Grolleau, who is also in charge of databases, supervises the global computing of the laboratory.
A special agent, Olivier Dupuis, coordinates health and Safety service, under the responsibility of the director.
LESIA’s primary role:
LESIA is at the forefront of scientific advances in all areas where it is involved thanks to: the scientific results obtained from the instrumentation that was designed and produced within the laboratory, in the different research areas of the centre; the use of large national and international funding; the developed simulations and theoretical work.
LESIA’s scientific activities are classified in five main themes (Star, High Angular Resolution and Astrophysics, Planetology, Plasma Physics and Solar Physics), where it also focuses on fifteen major astrophysical topics, as well as on ten technical areas.
LESIA is the laboratory in charge of the coordination of the "Laboratoire d’Excellence" ESEP (Space Exploration of Planetary Environments), a network of nine laboratories working on space thematics.
With its data processing center LEOPARD, the laboratory is also heavily involved in many aspects of technics and technologies of information, for the development of instrumental methods and for data analysis.
Finally, LESIA has many assignments within the astrophysics community (service tasks for the community, institutional responsibilities, teaching) and is largely involved in missions for the spread of scientific culture.
