Had a great time at #GWB2026 discussing food and health with students. The slogan competition was a fun time.

La #IUPAC, la organización que pone orden en el mundo de la química —desde los nombres de los elementos hasta cómo se escribe cualquier compuesto—, se traslada a Europa, repartida entre Roma y Málaga (al menos hasta 2029), después de estar 29 años en Carolina del Norte.

I will be speaking at an upcoming #GWB2026 event about food and health in Lucknow.
Interesting examples on Awadhi cuisine and its relation to women health will be presented. Do stay tuned.

At #EuroMOF2025. The sheer number of MOFs named after uni/company, changing the number when only difference is metal ion used to make the MOF and name gives no indication what the chemical composition is from "xxMOF-n" shows that we need a standardised nomenclature desperately. #IUPAC #chemsky #MOFs

After it wasn't possible for me to go to KL in person to receive my recent IUPAC award, I met with @francesbiophys.bsky.social yesterday who kindly brought it with her to Melbourne. Thank you!

This award is testament to the awesome work of my team. Proud of you all!
