Dr. Tekla Tammelin, Principal Scientist in Fibres and Biobased Materials Research area and Docent in Bioproduct Technology at Aalto University. She graduated from Helsinki University of Technology (now Aalto University) in 2006. She is acting in a senior expert network in VTT SONE (Solutions for Natural Resources and Environment) Business Area with an internal role as Principal Investigator with the strategic research responsibility area of “Nanocellulosic materials”. Expertise areas include the development of novel biobased materials, especially nanocellulosic materials and hemicelluloses as well as formation of structures (films, foams and webs) and the applications thereof by understanding the structure-function interdependencies and decisive role of interfaces. Presently promoting and creating novel innovative biomaterial concepts towards future breakthrough solutions. These concepts include biobased structures as selective membranes, intelligent packaging materials and as electronic devices and energy materials. She is a main inventor of the recent patent related to the larger scale preparation method for nanocellulosic films. She has published ~60 peer-reviewed papers and more than 100 scientific meeting proceedings. She received Akzo Nobel Nordic Research Prize in 2010 in the area of surface chemistry of cellulosic fibres and in 2016 she received the VTT Award on Exceptional Scientific Excellence.
