  • Control

Education

PhD in Electrical Engineering and Computer Science, MIT, 1999

Research Statement

Dr. Hadjicostis' research focuses on computational and signal processing architectures, data networks, and dynamic and discrete event systems. Areas of particular interest include fault detection, isolation and tolerance, hierarchical and/or distributed control, and applications of coding, graph theory and algebra toward the analysis of systems and networks.

In his work, Dr. Hadjicostis has developed coding techniques for detecting and correcting component failures or communication lapses in dynamic environments (which include digital controllers, sequential or parallel algorithms and discrete event systems). He is currently investigating how these ideas can lead to the construction of next-generation computing systems by enabling novel manufacturing technologies and by producing reliable systems out of unreliable (but possibly faster and less expensive) components. Another aspect of Dr. Hadjicostis' research involves techniques for monitoring, controlling and providing security and fault tolerance to the large-scale systems and networks that emerge as a result of today's high networking connectivity; applications of particular interest include power systems, traffic and air-traffic networks, financial markets, and other complex digital systems. In the area of discrete event systems, Dr. Hadjicostis is interested in systematically developing analysis tools and distributed and/or hierarchical control algorithms.

Research Interests

Fault-tolerant combinational/sequential systems; error control coding; applications to Boolean networks and genetic regulatory models; Monitoring, diagnosis and control of large-scale systems and networks; Model classification and anomaly detection; applications to network security, biosequencing and medical diagnosis; Discrete event systems; Algebraic system analysis; Coding and graph theory.
