About

I am an Associate Professor in the Department of Computer Science at Norwegian University of Science and Technology (NTNU). I am affiliated with Computer Architecture Lab (CAL) in the Computing Unit. Before joining NTNU, I was a post-doctoral researcher at Uppsala University, Sweden and the University of Edinburgh, UK. I received my PhD from UPC, Barcelona in 2014. My current research focuses on improving the efficiency of large-scale datacenters through improvement in processor microarchitecture and memory systems. My previous work explored hardware/software co-designed processors (think of Nvidia Denver) as an energy-efficient alternative to conventional (hardware only) processors. I have also investigated dynamic code translation and optimizations, especially vectorization.
