1998 – 2002 Associated Researcher (Grade C tenure-track) IESL - FORTH, Greece.2001 – 2005 Adjunct Professor Department of Materials Science and Technology, University of Crete, Greece.2005 – 2008 Adjunct Professor Department of Physics, University of Crete, Greece.2002 – 2012 Principal Researcher (Grade B tenure) IESL - FORTH, Greece.2012– present Research Director (Grade A open-end) IESL - FORTH, Greece.1988, B.Sc., Physics (upper 2nd class honors) Dept.1993, D.Phil., Chemical Physics School of Chemistry & Molecular Sciences, University of Sussex, UK.He has published more than 100 refereed journal articles and disseminated his research through invited lectures (25) and numerous contributed talks (47) at international conferences (h-index= 26 ResearcherID: F-6771-2011). Moreover, he has been the advisor of young scientists that have completed their PhD (5) or MSc (10) research in materials physics/ chemistry, and was honored to be a “Fulbright Fellow – Greece” (2016-17) for lecturing and conducting research in the United States. In addition, he served in posts such as, in conference program committees and a panel member of R&D actions supervised by GSRT. Dr Lappas has initiated and successfuly led a number of international research projects.
He leads the Quantum Materials & Magnetism lab at FORTH. His team works in the field of experimental condensed matter physics and materials science, studying electronic phenomena and phase transitions in correlated electron systems and other quantum materials that tackle society’s challenges in energy.
As a Visiting Researcher and principal investigator, he has been working at world renowned large-scale synchrotron X-ray (Brookhaven National Lab), neutron (Rutherford Appleton Lab) and muon (Paul Scherrer Institute) science facilities in USA and Europe for the last 25 years. In parallel, Dr Lappas has taught materials physics courses, as an Adjunct Professor in the Univ. He was elected to a tenure-track Researcher (1999) in Materials Science at the Institute of Electronic Structure and Laser in FORTH, where he is presently a Director of Research (equivalent to a University Professor position). After his compulsory military service (1996-97) in Greece, he moved back to Sussex as a Temporary Lecturer (Inorganic & Physical Chemistry curriculum). During 1993-95, as a Research Fellow in the Inorganic & Solid State Chemistry division of Sussex University, he became interested in the field of fullerene-based magnets & superconductors. in Chemical Physics (1993) from the School of Chemistry & Molecular Sciences at the Univ. in Physics (1988) from the University of Crete and a D.Phil.
