About Dr. Joanna Buckley

Aged seven, the gift of a chemistry set sparked Jo's interest. She completed every single experiment, charring the kitchen work surface with the spirit burner and staining the dining room carpet with indicator in the process.

Thankfully, her practical technique improved and she studied for a masters degree and PhD at the University of York, where her research focused on nanomaterials.

Always passionate about science communication, Jo now works for the Royal Society of Chemistry and is based at the University of Sheffield, helping to promote chemistry in the region. She writes and talks about science whenever she can to whoever will listen.
