Indigo grew up in Amsterdam and obtained her BSc degree in Chemistry at the University of Amsterdam in 2017 after a research project in the group of Prof. Joost Reek on tandem catalytic reactions in metallacages. She continued her studies with the joint degree programme of the University of Amsterdam and VU University Amsterdam. During this period, she carried out a research project in the group of Prof. Jan van Maarseveen on the synthesis of ring-functionalized [2]rotaxanes. For her Master's research project, she returned to the group of Prof. Joost Reek to work on the post-functionalization of covalent imine-based cages for catalytic in vivo applications. After obtaining her MSc degree, she joined the group in March 2020 to work on signal transduction in synthetic molecular systems.
