John was born in Seoul (South Korea) and grew up in Leeuwarden (The Netherlands). He obtained his BSc degree in Chemistry at Van Hall Larenstein University of Applied Sciences (2018). During his studies, he performed an internship at BASF – Resins and Additives, where he worked on NIR spectroscopy for the determination of hydrosilylation processes; a research internship at Symeres, where he worked on the development of a continuous flow photoreactor for intramolecular [2+2] cycloadditions; and a research internship at the University of Groningen in the group of Prof. Alex Dömling, where he worked on adenine mimetics based on multicomponent reactions.
After graduating, he worked briefly at FrieslandCampina LQS, and in 2019 he joined the Stratingh Institute as a Research Technician, managing and maintaining lab equipment for the Feringa, Harutyunyan, Otto, Barta, and Roelfes groups. In 2022, he obtained a full contract, and his responsibilities shifted to supporting the Feringa, Brown, Kudernac, and Klein groups.
In the Feringa group, he is working on the optimization and upscaling of molecular motor synthesis, making gram-scale synthesis of complex molecular motors possible.
