Research

The pursuit of Moore's Law is slowing and the exploration of alternative devices is underway to replace the CMOS transistor and traditional architectures at the heart of data processing. My research, as head of the Heterogeneous Systems Design group at the Lyon Institute of Nanotechnology, focuses on the development of novel energy-efficient computing architectures based on advanced, emerging and alternative devices, specifically exploring:

• Energy efficient edge computing based on advanced and emerging devices and paradigms: devices for advanced and emerging logic and computation (vertical nanowire FETs, ferroelectric non-volatile devices), requiring new logic gate structures and rethinking of computing paradigms and associated architectures;

• Silicon photonics for high-performance and in-network computing: devices for data transport in emerging manycore architectures (optical interconnects based on silicon photonics), requiring novel communication topologies exploiting wavelength vectors, and methods for performance comparison against conventional interconnect structures;

• Design-technology co-optimization methods for heterogeneous integrated systems: "More than Moore" systems using new integration technologies (vertical integration in three dimensions, heterogeneous integration), requiring new design methods and tools to manage both complexity and heterogeneity.
