She received the B.Sc. degree in Geology Science from the University of Palermo, Italy and the M.Sc. and Ph.D degrees from the University of Paris XI (ORSAY), Lab. of Hydrology and Isotope Geochemistry, in 1988 and 1991 respectively. She worked as postdoctoral fellow at the same Laboratory of Isotope Geochemistry from 1991 to 1992. She then moved to the University of Thessaloniki as collaborating Researcher at the School of Geology (1993-1996). She joined NCSR Demokritos in 1996. Since, she worked as postdoctoral fellow at the Laboratory of Isotope Hydrology I, Inst. Physico-Chemistry, NCSR "Demokritos" and as collaborating Researcher at the same lab. She was the founder of the Stable Isotope Unit (SIU)- the only Isotope Laboratory in Greece with an international collaboration network. SIU is well equipped with state-of-the-art infrastructure for the analysis of stable isotopes in bio-geo and natural materials. Dr Dotsika is currently Director of Research at the Institute of Nanoscience and Nanotechnology (INN), leader of the ‘Material and Environmental Isotope Geochemistry’ (MEIG) research group, of NCSR Demokritos. She coordinates the ‘Culture Heritage’ program of the Institute, and is the head of ‘Stable Isotope laboratory’ (SIU). Since 2009 to present she is Associate member of ‘Consiglio Nazionale delle Ricerche ‘(C.N.R.), Institute of Geosciences and Earth Resources, Pisa in Italy. Dr Dotsika was National Representative for four Actions COST. She is the principal investigator for many research projects with focus on Isotope Geochemistry. She participated in the EC project E.U., and in bilateral projects. She was also leader in International Atomic Energy Agency, in C.N.R. and in General Secretariat for Research and Technology (GSRT) projects, aiming to enhance Isotope facilities and know-how in Isotope Geochemistry focusing on material science, environmental evolution and cultural heritage. She has several International collaborations in particular with partners from the EU countries. She has (co)authored more than 150 scientific publications (including 60 in referred scientific journals, 7 book chapters and 83 papers in international (70) and National (13) conference proceedings). She has also trained 9 PhD, 8 Master students and numerous students towards their Diploma Thesis. She is reviewer in 21 international Scientific Journals.
