External Advisory Committee

Iannis Dandouras (IRAP)

Iannis Dandouras is Research Director at CNRS, at the IRAP laboratory (Institut de Recherche en Astrophysique et Planétologie) in Toulouse, France. His research interests include solar wind-magnetosphere coupling, terrestrial magnetosphere dynamics, and in particular the dynamics of the inner magnetosphere: the area where multiple particle populations coexist and interact (plasmasphere, ring current, radiation belts, exosphere). But his research interests include also the dynamics of the magnetospheres of the outer planets, and in particular Saturn's magnetosphere and its interaction with Titan, this moon with a very dense atmosphere, resembling the pre-biotic atmosphere of Earth.

He obtained his BSc in Physics from the University of Athens, Greece, his DEA (MSc) in Space Physics from the Paul Sabatier University of Toulouse, France, and his Doctorat d' Etat (PhD) from the same University. He has been a Post Doctoral Researcher at the University of California, Berkeley, and at the University of Washington, Seattle.

Dr. Dandouras is PI (principal investigator) of the CIS ion spectrometry experiment onboard the four Cluster spacecraft of ESA, and Deputy PI of the HIA experiment onboard the Double Star mission, which is the fruit of cooperation between the Chinese National Space Administration (CNSA) and ESA. He is also involved as co-investigator in the MIMI experiment onboard the Cassini mission to Saturn, in the IMPACT experiment onboard the STEREO two-spacecraft solar study mission, and in the SERENA experiment which is under preparation for the BepiColombo mission to Mercury.

Dr. Dandouras has been President (2008-2011) of the Solar-Terrestrial Sciences Division of the European Geosciences Union (EGU). He is now serving in the French Committee for SCOSTEP (Scientific Committee of Solar Terrestrial Physics) and in the ESA Cluster Science Operations Working Group. He is also a past member of the CNES Sun-Heliosphere-Magnetosphere Advisory Group, of the French Space Weather Working Group, of the CDPP (Centre de Données de la Physique des Plasmas) Implementation Working Group, and of the Scientific and Technical Council of CESR (Centre d'Etude Spatiale des Rayonnements). He has also participated in research teams of ISSI (International Space Science Institute), and is currently member of the ISSI research team "Resolving Current Systems in Geospace".

He has been supervisor of 10 PhD students. He has published more than 200 scientific articles in international refereed journals and 40 papers in conference proceedings and special volumes/books, cited 3474 times, and has given more than 30 invited talks at international conferences.

François Lefeuvre (LPCE)

François Lefeuvre is presently Emeritus Director of Research at CNRS. Since his first years in research, his main scientific interest is in the development of analysis techniques for waves and turbulences in space plasmas, and in the studies of wave-particle and wave-wave interactions triggered by natural and artificial plasma waves in the space environment of the Earth. He was a member of the S300 Scientific board in the European GEOS mission, Co-Investigator of wave experiments on the French-Soviet AUREOL 3 satellite and on the French DEMETER microsatellite, Principal Investigator of a wave experiment on the Russian INTERBALL mission, Chairman of the WEC consortium for the ESA-NASA CLUSTER mission (1992-1993) and PI mission for the French project TARANIS (2003-2008). He was Director of Laboratoire de Physique et Chimie de l'Environnement (LPCE - Orleans, 1994-2003), chaired the ESA Space Weather Working Team (2002-2005), was President of the International Union of Radio Science (URSI, 2005-2008, 2009-2011), and is presently Past President of URSI.

David Gary Sibeck (NASA)

Dr. Sibeck's research focuses upon the interaction of the solar wind with the Earth's magnetosphere and ionosphere, the regions where most space weather effects are felt. Following a post-doc working on AMPTE/CCE observations of the Earth's radiation belts from 1985-1987, he advanced to a Principal Professional Staff position at nearby JHU/APL. Here he became an AGU fellow, received the AGU's MacElwane award, actively participated in the Czech, Russian, and Slovak Prognoz and Interball spacecraft programs (ultimately receiving a medel from Charles University in Prague for his services), led successful efforts to preserve and provide endangered NASA magnetospheric data sets, organized a series of competitively awarded research groups at Switzerland's Internation Space Science Institute, and participated in a study to define the USAF's space weather needs.

Upon moving to NASA/GSFC in 2002, he was almost immediately detailed to NASA/HQ, where he served a two-year term as Deputy Program Scientist setting up and running the Living With a Star (LWS) program, NAASA's preeminent space weather program. Since returning to NASA/GSFC in 2004, his work as Project and Mission Scientists has focused on the remarkably successful THEMIS/ARTEMIS Explorer missions and preparations for the imminent LWS Radiation Belt Storm Probe mission. In recent years he has taken on the leadership of a cross-disciplinary group prototyping a wide field-of-view soft x-ray imager with applications for solar wind-magnetosphere and solar wind-planetary applications. Nevertheless, community service and research remain at the core of his interests. He has served as editor or guest editor for several major journals and presently leads the National Science Foundation's Geospace Environment Modeling program, which organizes the preeminent annual meeting of magnetospheric physicists in the United States. He was on a committee that reviewed the full range of NSF Upper Atmospheric activities and he has served continuously on the ESA Cluster Active Archive advisory committee for the past decade. His most frequently cited first-authored papers concern the responses of the Earth's dayside magnetosphere, ionosphere, and magnetotail to varying solar wind conditions. It has been his privilege to learn from and mentor a series of extraordinarily productive postdoctoral students.

Publications: 245 refereed, of which 72 are first-authored (h-index = 37, cited 4539 times by other authors). First-authored topics range from solar wind structures to transient events in the Earth's equatorial and polar ionosphere. Recent research focuses upon simulations, microphysics of the foreshock, the magnetopause, and geomagnetic pulsations
