Constantia Alexandrou received a BA degree with First Class Honors in Physics from the University of Oxford in 1980 and a PhD in Theoretical Strong Interactions Physics from the Massachusetts Institute of Technology, USA in 1985. She held research positions at the Paul Scherer Institute, Switzerland and at Erlangen University, Germany. She is a Professor at the Physics Department of the University of Cyprus, where she leads state-of-the-art research in Lattice Quantum Chromodynamics (QCD) and in studies of hadron structure. She is a member of the European Twisted Mass Collaboration (ETMC) and the Lattice Hadron Physics Collaboration (LHPC) that include major European and US research groups in Lattice QCD. She heads the Lattice QCD Computational Lab. at the University of Cyprus, which operates clusters dedicated to Lattice QCD calculations. She is coordinator of several research programs, has numerous scientific publications and invited talks at international meetings and has organized several workshops in Cyprus and abroad.She is a member of the Senate of the University of Cyprus, the representative of Cyprus at IUPAP and a delegate of Cyprus to SESAME. She served as the first Head of the Department of Physics and she was Vice-Chair of the Interim Governing Board (IGB) of the Cyprus Institute from 2004 to 2007. Since January 2008 she is Chair of IGB of the Computational-based Science and Technology Research Center of the Cyprus Institute.
