About me

I am Associate Professor at the School of Electrical, Computer & Biomedical Engineering at Southern Illinois University Carbondale and the director of the Embedded Systems Software Lab, which focuses on:

  • Machine learning: Approximate computing, heterogeneous hardware accelerators, neural network optimizations, and hardware/software co-design.
  • System optimization: Application customization, power-aware scheduling, and memory management.
  • Many-core systems: Application mapping, network-on-chip architectures, run-time resource management, design and exploration of heterogeneous platforms, and resource contention minimization.
