The main objective of the Curtis Analytics is to help the food industry mitigate the acrylamide problem in food. Curtis Analytics is the fastest asparagine testing service company in the UK and hold contracts with five major bread and breakfast cereal producers, farmers and crisp producers. Curtis Analytics was established by Dr Tanya Curtis at the end of July 2017.
Formation of the company was encouraged by Rothamsted’s then head of Business Engagement and Commercialisation, Andrew Spencer. He believed that Curtis Analytics would be very successful, based on his previous experience with the similar spin-off and start-up businesses. The company started operating in 2017 and was entirely supported by Dr Tanya Curtis.
Tanya Curtis
Dr Curtis completed her PhD at Rothamsted Research as a postgraduate student registered in the Food Biosciences Department at Reading University. She continued investigations into acrylamide mitigation in wheat through her post-doctoral studies. Her BBSRC-funded £1.6M link project, BB/I020918/1, delivered 11 research papers in internationally reviewed journals and several invitations to International conferences. The last two papers provided bases for the agronomical improvement of wheat management for acrylamide reduction and mitigation that were incorporated into EU regulation: COMMISSION REGULATION (EU) 2017/2158 of 20 November 2017, establishing mitigation measures and benchmark levels for the reduction of the presence of acrylamide in food.
Sarah Usher
Dr Usher Completed her PhD in Epigenetics at Rothamsted Research in 2009. She has since worked as a post-doctoral scientist generating and characterising GM plants which produce beneficial oils. Dr Usher has extensive experience in molecular biology, biochemistry and analytical techniques, with over 18 years in the laboratory.
Ondrej Kosik
Ondrej is an experienced plant glycobiologist with a demonstrated history of working in the industry. His main interest is in plant cell wall architecture and its influence on human health and nutrition. Ondrej got his PhD in Biochemistry as part of Marie Currie training network. He held a postdoctoral position at Department of Biochemistry at University of Cambridge, followed by his second postdoc at Rothamsted Research. Ondrej is a specialist in method development, liquid chromatography, mass spectrometry, size-exclusion chromatography, glycobiology, enzymology and biotechnology. Ondrej joined Curtis Analytics in April 2019, bringing his expertise and passion for science.
Hiba Hassoun
Hiba is an experienced molecular biologist, passionate about science, with a BSc in Microbiology from University of Hertfordshire. After graduation, she worked at the Institute of Natural Sciences in Auckland, New Zealand, followed by a Scientist position at Molecular Diagnostic Company, Ely, Cambridge. She has experience in a medical microbiology lab, working for NHS as a biomedical support scientist. Hiba joined Curtis Analytics in April 2019, loving the new change of direction in her science career.
