Research activities

Research areas:
Software systems architecture, cyber-physical systems, theoretical verification of behavior, and business process modeling. Emphasis on collaboration between cyber-physical services to build complex systems.

PhD Topics:
In the contexte of Cyber-physical systems (CPS), CPS processes is one of the challenging features. My research focuses on proposing a set of extensions for BPMN to properly and accurately model CPS processes. In particular, we focus on time properties to provide supports for the time dimension in CPS.
