Professor Aku Seppänen leads a research team, which develops and applies computational and statistical methods for solving inverse problems arising from (physical) science and engineering. The main applications are: 1) environmental monitoring and modeling (especially measuring atmospheric aerosols and remote sensing of forests), and 2) tomographic imaging (especially electrical impedance tomography, industrial process tomography, non-destructive material testing and structural health monitoring; special emphasis is on concrete and other cement-based materials and structures).
