Προσωπικό Προφίλ

Christoforos Hadjicostis is Professor of Electrical and Computer Engineering at the University of Cyprus. He received S.B. degrees in Electrical Engineering, Computer Science and Engineering, and Mathematics, the M.Eng. degree in Electrical Engineering and Computer Science in 1995, and the Ph.D. degree in Electrical Engineering and Computer Science in 1999, all from the Massachusetts Institute of Technology, Cambridge, MA. He has served as Assistant and Associate Professor at the University of Illinois at Urbana-Champaign, where he was affiliated with the Department of Electrical and Computer Engineering, the Coordinated Science Laboratory, and the Information Trust Institute. From 2008-2010, he served as Chair of the Department of Electrical and Computer Engineering at the University of Cyprus. His research focuses on fault diagnosis and tolerance in distributed dynamic systems; error control coding; monitoring, diagnosis and control of large-scale discrete event systems; and applications to network security, anomaly detection, energy distribution systems, medical diagnosis, biosequencing, and genetic regulatory models.

Profile Information

Christoforos Hadjicostis received S.B. degrees in Electrical Engineering, in Computer Science and Engineering, and in Mathematics, the M.Eng. degree in Electrical Engineering and Computer Science in 1995, and the Ph.D. degree in Electrical Engineering and Computer Science in 1999, all from the Massachusetts Institute of Technology, Cambridge, MA. In August 1999 he joined the Faculty at the University of Illinois at Urbana-Champaign (UIUC) where he reached the rank of Associate Professor with the Department of Electrical and Computer Engineering, Research Associate Professor with the Coordinated Science Laboratory, and Research Associate Professor with the Information Trust Institute. In 2007, Dr. Hadjicostis joined the Department of Electrical and Computer Engineering at the University of Cyprus, where he served as the Department Chair from 2008 to 2010. Dr. Hadjicostis teaches and conducts research in the areas of systems and control, communication, and digital signal processing. His current research focuses on fault diagnosis and tolerance in distributed dynamic systems; error control coding; distributed algorithms for monitoring, diagnosis and control; discrete event systems; and applications to network security, anomaly detection, medical diagnosis, and biosequencing. Dr. Hadjicostis serves as an Associate Editor for IEEE Transactions on Automatic Control, for the Journal of Discrete Event Dynamic Systems, and for IEEE Transactions on Control Systems Technology; he has also served as an Associate Editor for the IEEE Transactions on Circuits and Systems I (Regular Papers) and as an Editor on the Conference Editorial Board of the IEEE Control Systems Society.
