Ana Lorena Morales-García is from Pachuca in Mexico. She got her degree in Chemistry in 2008 at Universidad Autónoma del Estado de Hidalgo, which is the State University; Pachuca is the capital of Hidalgo. We were lucky to have Ana here working on the interaction between bacteria. She worked in a collaboration with the Department of Animal and Plant Sciences with Dr (now Prof.) Steve Rolfe as co-supervisor. Ana came to Sheffield in September 2008 to do a PhD with integrated studies, which meant that her first year involved taking the MSc in Nanoscale Science and Technology, which is offered jointly with the University of Leeds. Ana spent her PhD mapping individual cells with atomic force microscopy, especially the chemical force variant, in which the AFM tip is coated with a monolayer of polymers or metal. She also studied bacterial interactions with biofilms. Her work was part of the Cell-Mineral Research Centre of the University of Sheffield. After submitting her thesis, she joined the Low-Dimensional Chemistry programme grant team to work on polymer surface diffusion. Ana then took a fully funded postdoctoral position from P&G, who were impressed with her thesis. She did more postdoctoral work with them but this time at Newcastle University before P&G bowed to the inevitable and hired her, and Ana is now a Senior Scientist there. On Wednesday May 7, 2014 Ana successfully defended her thesis before her examiners, Professors Cameron Alexander (University of Nottingham) and Catherine Biggs. Catherine was then at the University of Sheffield but left for Newcastle University.

And finally...

Photograph of Ana with Sir Harry and Lady Margaret Kroto.

In June 2011 Ana won the Kroto Science Education Prize for her outreach work, particularly that with Sheffield's Somali community, which is quite large. She is photographed here with Sir Harry Kroto and Lady Margaret Kroto. Sir Harry, shared the 1996 Nobel Prize for Chemistry and is, like Lady Margaret, a graduate of the University of Sheffield.
