Professor P. C. Kelires originates from the town of Akanthou, in Famagusta District, Cyprus. He is married and has three children. He got his B.Sc. degree (1981) in Physics from the University of Athens, Greece, and his Ph.D degree (1987) in theoretical Solid State Physics from the State University of New York, Albany (USA). He was IBM Research Division post-doctoral fellow at the world-renowned T. J. Watson Research Center, Yorktown Heights, New York (1987-89). He was elected as Assistant Professor in the Physics Department of the University of Crete (Greece) in 1989, and he got tenure as Associate Professor in 1994. He was promoted to full Professor in 2003. He was elected as Professor of Materials Science in the Cyprus University of Technology in 2006. His research field is Computational Materials Science and Condensed Matter Physics, with emphasis in atomistic simulations and modelling of materials, especially in simulations of crystalline and amorphous semiconductor systems, alloys, and heterostructures. He has significantly contributed to the fields of amorphous carbon and group-IV compounds and alloys, such as SiGe and SiC. An early pioneering contribution was the use of the semi-grand canonical statistical ensemble in Monte Carlo simulations, which made it possible to study ordering/segregation phenomena in semiconductor alloys. Other pioneering contributions were made in the field of amorphous carbon (a-C) regarding its stability, elastic properties and stress state. Most notable was the development of a theory of atomic level stresses and local moduli for the analysis of intrinsic stress and local rigidity of a-C. More recently, his team has developed strong activities in the simulations of Si nanocrystals, of heteroepitaxial semiconductor quantum dots, and of nanostructured and nanocomposite carbon materials. He has given more than 70 invited talks on the above topics in major international conferences and workshops. He has organized (chaired) six international conferences related to crystalline and amorphous heterostructures and nanostructures. He has published many papers in high-impact scientific journals of the field, such as Physical Review Letters. Prof. Kelires served as a member of the council of the European organization for computational sciences CECAM. He served as the National Representative of Cyprus to the FP7 programme of the EU in the field of "Materials, Nanosciences and Nanotechnologies". He is an Outstanding Referee of the American Physical Society and a member of the editorial board of Scientific Reports (published by Nature).
