Biography

Marlen Suller is Managing Director for Clinical Diagnostics EMEA at Magentus, a global health technology company whose products are used by more than 80 NHS organisations across the UK. Before joining Magentus, Suller led the global In Vitro Diagnostics Software division at Dedalus, where they consolidated fragmented portfolios and reorganised the global workforce. Earlier, at Siemens Healthineers, Suller led global organisations and strengthened managed pathology services for NHS Trusts. Suller is a frequent commentator in UK health-technology media, arguing that NHS diagnostics reform requires interoperable, connected data infrastructure rather than simply increased testing activity, and that the National Cancer Plan cannot succeed without such infrastructure.
