Illuminating Chemistry Athena Swan Accreditation Achieved Data

Summer 2013 Science day: illuminating chemistry Data, calculation and experiment Athena Swan accreditation achieved Keeping the IT systems operational As I see it... Tim Dickens leads the IT team within the chemistry department, having joined from GlaxoSmithKline five years ago. He tells Sarah Houlton about the problems the computer officers face, some of the current projects they’re working on – and what they do all day!
