Dr Filby graduated summa cum laude from the University of Huddersfield, achieving a 1st class honours in Biochemistry. He spent the third year of his undergraduate degree working for Syngenta in their central toxicology laboratory developing a flow cytometry-based assay for measuring intracellular cytokine production. After graduating, he undertook a PhD at the National Institute for Medical Research (NIMR) in Mill Hill, London. He worked on the Src family kinases LCK and Fyn in adaptive immunity obtaining his PhD in molecular and cellular immunology in association with University College London (UCL). Dr Filby remained in the immunological field, working as a post-doctoral researcher in the laboratory of George Kassiotis, also at the NIMR, working on models of retroviral infection. He then worked for a short time in the commercial sector before taking up the deputy head role of the cytometry core at the London Research Institute (now the Francis Crick). Dr Filby is currently director of the Newcastle University Cytometry and Single Cell Core Technology Unit. He leads a dedicated team of cytometry specialists with the sole aim of developing and implementing comprehensive, cutting edge cytometry methods for the wider research community at Newcastle University and beyond. A significant part of his focus is the development of novel cytometry-based techniques that have underpinned several high profile publications in journals including Science (2012, 2017 and 2018), Cell (2013) and Nature (2018). He also received the Cytometry Part A “paper of the year” accolade in 2011 for his work on debunking the myth of asymmetric division in adaptive immunity. He specialises in Imaging Flow Cytometry with a particular focus on “label-free” characterisation of cell phenotypes and transition states using machine and deep learning approaches. Dr Filby is also an International Society for the Advancement of Cytometry (ISAC) council member for "technology development". Prior to this, he was one of the first people selected as part of the “Shared Resource Laboratory (SRL) Emerging Leaders” programme. He serves on a number of ISAC committees and task forces and is heavily involved in a several educational initiatives for cytometry at both national and international levels. Dr Filby is driven by a passion to “measure all things of all cells in all biological systems”.
