King Kuok Hii

King Kuok "Mimi" Hii (born 23 December 1969) is a chemist whose fields of research include application of catalysis to organic synthesis. She is the Director of Imperial College London's Centre for Rapid Online Analysis of Reactions (ROAR).

Hii studied for both her BSc and PhD at The University of Leeds investigating multidentate ligand metal complexes under the supervision of Bernard L. Shaw.Postdoctoral studies at Oxford University in John M. Brown's group were followed by independent research at University of Leeds, Kings College London and in Imperial College London. In 2016 she was awarded a Professorship in Catalysis and in 2018 became the Director of the Centre for Rapid Online Analysis of Reactions.

Hii has investigated catalysis during her research career.In Oxford, she characterised intermediates of the Heck reaction. Hii also studied this reaction at King's College London. Hii has continued with this field of study producing over a hundred articles, reviews, book chapters and patents. These include articles, reviews and books on sustainable chemistry methods. In 2010 Hiijoined the Steering Group of the Engineering and Physical Sciences Research CouncilDial-a-Molecule Grand Challenge network and became a Co-Investigator on phase III of theproject in 2016. Hii has been awarded many grants, most notably a multi-million award from the Engineering and Physical Sciences Research Council in 2017 which, together with money from Imperial College London and industrial partners funded the set up of Imperial College London's Centre for Rapid Online Analysis of Reactions (ROAR).

In 2013, the Federation of Asian Chemistry Societies recognised Hii as an Asian Rising Star. Hii was also elected as a Fellow of the Royal Society of Chemistry. In 2016 Hii became co-editor in chief of the open access Chemistry Central Journal. In 2019 Mimi Hii was shortlisted for an Asian Women of Achievement Award.
