Andrea Sella (born February 1961) is a chemist and broadcaster based at University College London where he is a Professor of Inorganic Chemistry.

He studies rare-earth metals[1] and collaborates with several research groups on hydrogen storage, carbonitrides, and nanotube insertion chemistry.

He studied chemistry at Trinity College, University of Toronto, as an undergraduate and started research for a PhD under Professor Robert H. Morris on molecular hydrogen compounds.

His research interests include the molecular chemistry of the lanthanides, the confinement of elemental phosphorus inside carbon nanotubes, and the synthesis and properties of layered carbonitrides.

[8] Since February 2014, he has been a frequent guest speaker in a BBC World Service radio programme called "Elements".
