Alex E. Knight, FRMS


Alex received his BSc in Biochemistry from the University of Kent at Canterbury in 1990 and his PhD from the MRC Laboratory of Molecular Biology, Cambridge in 1994. He carried out postdoctoral research at the Whitehead Institute for Biomedical Research in Cambridge, MA, USA, and the University of York. In 2002, he moved to the National Physical Laboratory where he was a Principal Research Scientist in the Biotechnology Group.

Alex is intrigued by the potential of microbiomics and related fields of science to unlock new insights into individual health and well-being. The challenges of turning the large, complex data sets produced by modern bioscience into clear insights that consumers can use are fascinating, and will require a combination of statistical, bioinformatic, machine learning and related approaches.
