PhD in process engineering with research focuses in particle size, morphology and fractional classification analytics. Currently working on projects related to utilisation of biochemicals in different applications (e.g. mining processes,
flocculation as well as oil spill prevention and response). I have worked as a project manager and researcher in several Tekes, ERDF and company financed projects. I have worked also as a research fellow in Technical University Bergakademie Freiberg (Freiberg, Germany) during the autumn 2011. More than 40 published scientific publications in the field of wood based materials and their characterization.
