AmélieJuhinwinsESRFYoungScientistaward

Amélie Juhin is thewinnerof theESRF“YoungScientistof theYear2017”.Thisaward ispresentedevery year by the ESRFUsers’Organisation to a scientist aged 37 or younger for outstandingworkconductedattheESRF.ThisprizeisseenasencouragementfromtheESRFforayoungscientistwhoseworkhasalreadybeenrecognisedbypeersandproducedfruitfulresults.AmélieJuhinisaphysicistandspectroscopist,researcheratthe“Institutdeminéralogie,dephysiquedes matériaux et de cosmochimie” (CNRS/Université Pierre et Marie Curie-Sorbonne-Universités/Institut de Recherche pour le Développement/Museum National d’Histoire Naturelle). She wasawardedtheprizeforherexperimentalandtheoreticalstudiesofresonantX-rayscatteringandX-raydichroism,carriedoutattheESRF.AmélieJuhin’sresearchisfocusedonprobingtheelectronicandmagneticpropertiesofnanoparticlesandmolecularmagnets.Forthisresearch,sheusesthepowerfulX-raysproducedbytheESRF,theEuropeansynchrotron,inGrenoble.SheexploresboththeexperimentalandtheoreticalaspectsofsoftandhardX-rayspectroscopiesandhasdevelopedmagneticspectroscopieswithX-rays.Agedjust36,sheisalreadyrecognisedasaninternationalexpertinthisfield.AfterobtainingaPhDin2008fromtheUniversitéPierreetMarieCurie,inParis,AmélieJuhinpursuedapost-doctoralfellowshipattheDebyeInstituteforNanomaterialsScience,inTheNetherlands.ShewasrecruitedbytheFrenchNationalCentreforScientificResearch(CNRS)andjoinedtheInstituteofMineralogy,PhysicsofMaterialsandCosmo-Chemistry(IMPMC)in2010.HercontributiontothefieldofdichroismandX-rayresonantinelasticscatteringhasalreadyearnedrecognitionfromherpeersasdemonstratedbytheFarrelLytleAwardfromtheInternationalX-rayAbsorptionSocietythatshereceivedin2015andaBronzeMedalfromtheCNRSin2016.
