Research focus

Currently

My current research focuses on energy-efficient andd high-performance embedded systems. It covers a variety of design issues, including software mechanisms, architecture, and emerging memory and communication technologies. An important challenge is addressing the increasing heterogeneity of the target systems so that their energy efficiency can be ensured. The following research directions are covered:

• Energy-driven computing
• Heterogeneous embedded multicore system design
• Resource management in embedded systems
• Towards sustainable computing

In the past

In my previous research activity, I studied safety-critical and data-intensive embedded applications implemented on parallel or distributed architectures. The research was conducted at CRIStAL (formerly, Laboratoire d'Informatique Fondamentale de Lille - LIFL, from 2006 to 2012 in Lille) and IRISA (from 1999 to 2005 in Rennes) computer science laboratories.

A major objective of this research was to guarantee both execution correctness and performance (under real-time constraints). My research focuses on two complementary models of computation (MoCs): polychronous modeling associated with synchronous reactive approaches, and repetitive structure modeling associated with array-oriented data parallel programming. In the former, components interact without assuming a global or reference clock. In the latter, massively parallel structures can be specified via factorized repetitive dependency relations. On the basis of these MoCs, I contributed a reference monograph on synchronous programming in Signal language and a unique methodology to assist software-hardware codesign of system-on-chip.
