About me

I am a Research Associate at the University of Edinburgh working in the Horizon 2020 EU project, Bonseyes, looking into accelerating the execution of deep neural networks on resource-constrained devices. I obtained my PhD under the supervison of Dr. Mahesh K. Marina at the University of Edinburgh, Institute of Computer Systems and Architecture (ICSA).

My research interests are in:
  • accelerating deep neural networks running on resource-constrained heterogeneous systems
  • machine learning for context understanding
  • localization and tracking with mobile devices
  • low-energy computer vision systems
  • low-energy audio systems
