Last week I had the pleasure of attending the Netherlands’ Catalysis and Chemistry Conference (NCCC), where I presented my research on photobiocatalytic atroposelective biaryl coupling.
I’m excited to share that I was awarded the Royal Society of Chemistry @rsc.org EES Catalysis Best Talk Prize!

Last week I have defended my PhD in the beautiful Aula of the @rug.nl with a thesis entitled "Mapping the Sequence Landscape of an Artificial Enzyme". Such a huge diploma is proportionate to the immensely beautiful experience behind a PhD in the @roelfesgroup.bsky.social. Thank you very much to all!

This accomplishment would not have been possible without the tireless work of Ru Jiang and @fabricas.bsky.social and the expertise of Andy-Mark Thunnissen in solving the holoenzyme structure.
Great work everyone! 🏆
