Biography
1.6.2022 - 31.12.2025 in Prof. Ari Väisänen's Metal Analysis and Recovery Research group as a laboratory engineer. Laboratory executive in our hydrometallurgy laboratory (bench scale, mini-pilot equipment) and technical person in Circular Economy, also partaking in research and teaching duties.
Research interests
My current research is focused on analytical chemistry and circular economy with most relevant subtopic being recovery of valuable materials from industrial side streams using hydrometallurgical methods. I work as an executive in our Circular Economy Center of Expertise (CECE) hydrometallurgy laboratory (mini pilot scale of 1 kg / 10 L), where it is possible to study chemical recovery processes such as liquid-liquid extraction, solid-liquid separation, electrolysis and ion exchange. My instrumental expertise and responsibilities comprise, in this research environment, elemental determination using inductively coupled plasma-optical emission spectroscopy (ICP-OES), atomic absorption spectroscopy (AAS), flame photometry, UV-Vis spectrophotometry and, in the near future, X-ray fluorescence spectroscopy (instrument purchase pending).
Previous research in my doctoral sudies were focused on structural and synthetic chemistry, containing synthesis and characterization of new molecules and materials. There I have used characterization methods such as single crystal and powder X-ray diffractometry, NMR spectroscopy and thermogravimetry, but also supporting methods when needed.
