Joost Kimpel(-Kawabe)
Research Fellow

I am a postdoctoral research fellow funded by the Swedish Research Council, with affiliations at Imperial College London, Linköping University and OIST. I hold a PhD from Chalmers University of Technology (2025), an MSci from Tokyo Institute of Technology (2021), and an MChem from the University of Oxford (2019), with work spanning organic synthesis, polymer synthesis, teaching in chemistry, and organic electronics.
This fellowship focuses on mechanistic understanding and optimization of conjugated polymer synthesis through computation and catalyst design seeing that one catalyst to rule them all remains, alas, elusive. Teaching is especially meaningful to me, so I gladly seize any opportunity to mentor students or contribute to outreach and education.
When my head isn't in the chemistry clouds, I like to play boardgames, oft con over medieval lore, or going for a run, swim, cycle, or boulder. Together with my wife, I love exploring new places, trying out new restaurants, and having multi-hour karaoke sessions.
