Maria is a Lecturer in Analytical Chemistry in the School of Chemistry since October 2017. Maria graduated in Chemistry from the University Jaume I (Spain) in 2007 having spent a year as an Erasmus student at Cork Institute of Technology, Ireland. She then moved to the School of Chemistry at the University of East Anglia (UEA) where she obtained her PhD in Analytical Bionanotechnology (2012) under the supervision of Prof David A. Russell. Her PhD thesis involved interdisciplinary work on intracellular detection and quantification of pH and nitric oxide (NO) using nanoparticles and molecular probes. Her research focused mainly on the synthesis, characterisation, and biological application of functionalised nanoparticles which act as sensors and ratiometric sensors of pH, and on the chemical and biological evaluation of fluorescent molecules which act as markers of NO. Her PhD thesis was complemented with a European Society for Photobiology (ESP) supplement to the PhD Degree awarded in 2015.

From September 2012 to April 2017, Maria was a Postdoctoral Researcher at UEA under the supervision of Prof David A. Russell and Prof Rob A. Field (John Innes Centre). During this period, she worked on several multidisciplinary projects including: 1) the development of simple bioassays based on gold glyconanoparticles for the diagnosis of influenza virus and for the specific detection of Siglecs; 2) the use of double stranded DNA functionalised gold nanoparticles to rapidly determine the crosslinking of DNA duplexes by bisintercator ligands (with Prof M. Searcey, School of Chemistry, UEA); 3) the intracellular evaluation of fluorescent macrocyclic probes as markers of acidic organelles (with Dr F. Galindo, University Jaume I, Spain) and nanosensors for the imaging of compartmentalised NO (with Dr J. Gravilovic and Dr P. Thomas, School of Biological Science, UEA); and 4) the use of nanomaterials (gold, magnetic and upconversion nanoparticles) as drug delivery systems, especially for targeted photodynamic therapy (PDT) of cancer (with Dr Ll. Pérez, University of Barcelona (Spain) and University of Nottingham; and Dr T. Hirsch, University of Regensburg, Germany). Maria has also worked in the field of Forensic Sciences, performing research on the use of antibody functionalised nanoparticles for the detection of drugs and drug metabolites in latent fingerprints.

During her career, Maria has also gained experience in industry. She was an Analyst at Iproma S. L. (Castellón, Spain, from July to September 2006) and I worked as part of the Quality Control and Assurance teams at Johnson Matthey Pharmaceutical Materials (Cork, Ireland, from April to December 2007). During the final year of her PhD, she worked as an Analyst in the Anti-doping Laboratory for the London 2012 Olympic Games under the leadership of GlaxoSmithKline and the Drug Control Centre at King’s College London. From April to October 2017, Maria was a Development Scientist at Iceni Diagnostics (Norwich Research Park Innovation Centre), a company specialised on the development of carbohydrate based diagnostics with who she maintains strong links.

Maria has won several best oral and poster presentation prizes and was awarded the Roscoe Gold Medal for Chemistry and the Westminster Medal for the overall winner during the 2014 SET for Britain.
