Eira Seppälä

Background

Eira Seppälä joined Nokia Research Center in September 2004. Until the end of 2006 she was working with computational acoustics using finite-element, boundary-element, and finite-element-type methods. Beginning of 2007 Eira Seppälä started in Nano Systems team, where her interests are dynamic nonlinear properties of piezoelectric, ferroelectric, and ferromagnetic materials, as well as carbon-based materials and simulations at nano and multi scale.

Eira Seppälä received her Master's degree in Engineering Physics from Helsinki University of Technology, Finland in 1997 and her D.Sc.(Tech) degree in Engineering Physics from the same institute in 2001. The topic of her doctoral thesis, which was accepted with distinction, was ground state structure, domain walls, and external field response in random magnets.

During August 2001 - August 2004 Dr. Seppälä was as a postdoctoral staff researcher at Lawrence Livermore National Laboratory in Metals and Alloys group. There her interest area was dynamic fracture and plasticity in metals, which she studied using molecular dynamics simulations, and fracture surfaces of embrittled polycrystalline metals using computational mesoscale and optimization methods.
