Short presentation

I investigate modeling and measuring the effects of shared memory resources (caches and off-chip bandwidth) in multicore processors on power and performance. My work addresses both theoretical models and techniques for measuring actual behavior on real systems. Currently I am applying these techniques to improve task scheduling on heterogeneous systems, to predict power and performance, and to develop smart memory systems.

My courses


I received my PhD in Electrical Engineering from Stanford University in 2008. My PhD thesis was on programming for real-time embedded processing on many-core processors in the Concurrent VLSI Architecture Group working with William Dally. After my PhD I worked at Apple on the development of the first OpenCL implementation for heterogeneous parallel processing across CPUs and GPUs, and then as a postdoc researcher in computer architecture in the Dept. of Information Technology at Uppsala University. I was appointed assistant professor in 2010 in the architecture research group at Uppsala looking at parallel programming systems and optimizations as part of the UPMARC research project. In 2014 I was promoted to associate professor (docent, lektor).

In addition to research, I lead the ScalableLearning project to bring the benefits of active, flipped-classroom teaching to thousands of students in Sweden and abroad.
