Pirjo Marjaana PasanenPrincipal Scientist
My background is in Theoretical Physics. I got my PhD from Helsinki University Department of Theoretical Physics in 1996, on Topological Quantum Field Theories . The next three years I spend in Austin, Texas in Steven Weinberg's Theory Group as a post-doc, doing string theory and beyond - that is, trying to figure out why the world really is 11-dimensional .
And then, for something completely different...In 2000 I ended up in Nokia. No regrets so far ;-)
The first couple of years I was involved in projects related to electronics reliability and product development process improvement. In 2002 I switched to radio communications, and did research on information theory, physical layer algorithms and and medium access layer protocols of wireless communication systems. I was also involved with several very interesting projects dealing with system design for future 4th generation wireless systems, both in Nokia internal projects as well as the EU project WINNER .
In the beginning of 2007 it was time for a change again: currently I am doing research on nanotechnology.
My current interest include all things nano, starting from graphene, carbon nanotubes, nanodevices and nanosystems, to analog signal processing, RF applications and alternative computation methods. The general question is to figure out ways to do signal processing and computations with nanoscale elements, preferably in a way that has not been done before.
