Sunt doctor in fizica din decembrie 2009, cu teza de doctorat “Contributii la studiul unor fenomene neliniare in feroelectricii ceramici” (SUMA CUM LAUDE). Activitatea de cercetare, de pana acum, a fost consacrata studiului dependentei permitivitatii de campul electric aplicat pentru unele materiale ceramice pe baza de BaTiO3 si compozite ME cu aplicatii in electronica. Am fost reprezentantul Romaniei la Student Contest la 11th International Conference and Exhibition of the European Ceramic Society (ECERS), Cracovia, Polonia (2009), unde am prezentat o lucrare despre prepararea ceramicelor multiferoice prin metode chimice inovative, cu care am obtinut un premiu din partea juriului. Din punctul de vedere al cercetarii aplicative m-am ocupat cu prepararea si investigarea proprietatilor electrice pentru materiale feroelectrice precum BaTiO3 si solutiile sale solide, dar si compozite ME ferita de (Ni,Zn) cu BaTiO3. Din punct de vedere fundamental, am studiat modelele teoretice derivate din teoria Landau ce descriu variatia permitivitatii cu campul aplicat si am realizat o corelatie intre rezultatele macroscopice-modelele teoretice-particularitati de microstructura. Rezultatele stiintifice de pana acum s-au concretizat prin publicarea a 30 de lucrari, din care 16 in reviste cotate ISI, totalizand 4.66 punctaj ISI individual), co-autor la 3 brevete de inventie si peste 50 de prezentari la conferinte internationale (din care 3 prezentari invitate in domeniul compozitelor ME, si un premiu pentru cea mai buna lucrare a unui grup de tineri-ECAPD 2008). Am coordonat in calitate de director- 2 proiecte nationale: BD-Bursa de cercetare stiintifica/creatie artistica pentru tinerii doctoranzi cod 72/2007, si PNII-RU-TD Proiecte de cercetare pentru tineri doctoranzi cod 212/2007 si am fost membru al echipei de cercetare al altor granturi. Recent am devenit membru al echipei de cercetare a grantului PN II-RU-TE 187/2010. De asemenea sunt implicata in programul european COST SIMUFER MP0904, avand o tema de lucru in domeniu compozitelor ME. Publicatiile relevante in tematica grantului (selectie):

I obtained PhD in Physics in December 2009 with the thesis “Contribution to the study of non-linear phenomena in ferroelectric ceramics” (SUMA CUM LAUDE). The research activity was dedicate to the study of permittivity depende on applied electric field for some ceramics based on BaTiO3 and ME composites with application in electronics. I was Romania representent to Student Contest at 11th International Conference and Exhibition of the European Ceramic Society (ECERS), Cracow, Poland (2009), where my presentation was about preparation of multiferroic ceramics by innovative chemistry method. From application point of view I worked on preparation and investigation of electric properties of ferroelectric materials like BaTiO3 and its solid solution, but also ME composite, (Ni,Zn) ferrite with BaTiO3. From fundamental research point of view, I studied theoretical models derivate from Landau theory that describe permittivity variation with applied field and realized a correlation between macroscopic results- theoretical models-microstructure. The original results were published in 30 papers, 16 papers in ISI journals, having 4.66 individual ISI score). Also she was co-worker at 3 national patents and up to 50 participation at international conferences (3 invited talk in ME composite topic, and one award for best paper of a young researcher group at ECAPD conference 2008). I was director- 2 national project: BD-Fellowship for research/artistic creation for young PhD students code 72/2007, and PNII-RU-TD projects of research for young PhD students PN II code 212/2007, and was member in research team of other national and international grants. Recently, I'm become member of young researcher team of PNII-RU-TE 187/2010. Also I'm involved in European program COST SIMUFER MP0904, with a research topic in ME composites.
