PhD in organic chemistry, University of Jyväskylä 2012

Research interests: supramolecular chemistry, anion binding, macrocyclic receptors (calix[4]pyrroles, resorcinarenes), and colloidal structures including micelles and solid lipid nanoparticles.

Research methods: synthesis, complexation studies (NMR, ITC, UV-vis, fluorescence), and crystallography.

Previous research includes cation complexation, Langmuir films and solid lipid nanoparticles of resorcinarene macrocycles, and anion complexes of aryl amide foldamers.

Macrocyclic Receptors for Selective Anion Extraction

May 2018 - April 2023

The project aims to offer pioneering solutions for the selective binding of biologically and technologically important anions. The target anions include anti-inflammatory drugs with carboxylate groups, and valuable resources, such as phosphate and precious metals (Au, Pt, Co). The project focuses on advanced synthesis of selective receptors, characterization of the anion complexes and development of extraction methods for target anions from water.
