Tiina Rissanen
Biography
Post-doctoral researcher Tiina Rissanen (née Virtanen) works in the Department of Separation Science in LUT University and leads a team focused on Membrane research and bio-based substances. She is interested in membrane fouling mitigation, membrane based separation and fractionation or organic compounds, use of spectroscopic tools, utilization of natural phenolic compounds in surface modification and valorization of natural materials such as sheep waste wool. Her PhD project in green chemical technology focused on real-time monitoring of membrane fouling (especially with Raman spectroscopy) and on unveiling fouling mechanisms of ligneous and phenolic compounds. She holds a master's degree in nanoscience, majoring in organic chemistry from University of Jyväskylä.
