The Analytical Sciences Unit comprises a core staff complement and PhD students, as well as a varying number of short-term students and visiting workers.
Her PhD and early career was in applied molecular spectroscopy (infrared, Raman) and the design of novel sensors, including a patented probe head for infrared sensing using attenuated total reflectance. Subsequently she began to focus on quantitation using spectral data, and the emerging discipline of chemometrics – a branch of statistics particularly useful for handling the large datasets produced by modern analytical techniques. Applications of these methods have included several important food authentication issues – detection of adulteration in edible oils; processed fruits; meat products; coffee.
The arrival of ‘omics technologies in recent years has opened up new opportunities for the chemometrics specialist. Kate’s interests have expanded to include the application of multivariate statistics to many more high-dimensional data types. These include a wide range of spectral data types, especially those used in connection with metabolomics (NMR, GC-, LC-MS) and electrophoresis image data. She also has a long-standing interest in electromyography and the processing of digital waveforms. Most recently, her research has concentrated on treatments of data collected using low-field NMR spectroscopy.
Kate is author or co-author of around 80 peer-reviewed articles, as well as numerous conference proceedings, posters, book chapters and a textbook. She is a Senior Lecturer (Hon.) in the School of Chemistry at the University of East Anglia.

I have 20 years of experience in the fields of metabolomics and lipidomics. I use Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) to analyse many kinds of sample.
My subjects of interest are diverse. I developed methods for authentication and quality assessment of fruit purees, orange juice, green tea, dry-cured ham, and red wine. I applied the same methods to assessment of genetically modified Arabidopsis and tomato and potato varieties in relation to substantial equivalence.
Since 2005, my interests have broadened to include nutritional and microbial metabolomics. I now have expertise in metabolomics and lipidomics applied to mammalian, bacterial and yeast extracts.
I have 21 years experience in food science research. I spent 12 years at the Central Science Laboratory analysing organic contaminants in foods from packaging migration such as phthalate esters and acrylamide. I spent another 4 years at Cefas where I monitored the marine environments for organotins and brominated flame retardants. I also developed methods for the analysis of PAH metabolites in crustacean urine and fish bile and the analysis of paralytic shellfish poisoning in shellfish. Since arriving at IFR, I am responsible for the mass spectrometry facilities in the metabolomics group. I am involved in the team metabolomic projects, but also extend the use of the mass spectrometers to the proteomics and phytochemicals departments.
I am a biological mass spectrometrist, with strong interest in Proteomics. I have more than 10 years of experience in this research area, as proved by my 37 peer reviewed research papers, 3 book chapters. I obtained unique results which have granted my high visibility in Proteomic and an h-index of 15 (Scopus, August 2016). I have the Italian Qualification of Associate Professor in Biochemistry and Clinical Biochemistry.
I demonstrated for the first time the powerful of proteome profiling in the analysis of food in the Chemical Safety (allergens and fining agents) and Integrity (related to raw ingredients) area, in collaboration with food manufacturing, and analytical sciences sector.
My actual Research interest is the understanding of the interaction between Microbiota and host gut barrier and the molecular mechanism involved in the maintenance of health and prevention of disease.
Kathryn Cross read Biology at the University of Hull, graduating in 2001. She then spent 4 years at the Public Analysts laboratories in Norwich where she managed the water chemistry laboratory, testing both potable water for suitability for drinking and effluent water for consent to discharge. Kathryn started at IFR in 2006 as an Assistant Microscopist, gaining expertise in preparing and imaging samples for both light microscopy and electron microscopy. Since 2011, she has taken over the running of IFR’s Microscopy department, producing images for numerous journal papers and front covers.
