Short bio
Dr. Timo Aalto has worked at VTT since 1997 with the primary research focus on silicon photonics. This makes him one of the pioneers in the field. He received his M.Sc. and D.Sc. degrees in optoelectronics technology from the Helsinki University of Technology in 1998 and 2004, respectively. He leads the Silicon photonics team that is the key user of VTT's clean room facility in Espoo (Micronova). He has >80 peer-reviewed journal and conference publications. He has reviewed EU projects, journal articles and theses, and written one book chapter. He has coordinated several large projects funded by EU, the European space agency, national funding organizations and industry.
