Iain Johnston is a Professor in the Faculty of Science and Technology at the University of Bergen. His undergraduate was in Natural Sciences at Cambridge and his doctorate was in Theoretical Physics at Oxford with Ard Louis. He did a postdoc with Nick Jones at Oxford, focussing on how mitochondria vary within and between cells. He then moved to the Department of Mathematics at Imperial College London to take up an independent MRC research fellowship, studying the role that physical and genetic variability in mitochondria play in human disease and plant bioenergetics. He then took a Birmingham Fellowship in the University of Birmingham School of Biosciences to develop laboratory and fieldwork approaches to study plant organelles in parallel with a Turing Fellowship from the Alan Turing Institute, before moving to sunny Bergen.
Kazeem Dauda is a postdoctoral fellow in the research group HyperEvol: Combatting Antimicrobial Resistance (AMR) funded by Trond Mohn Stiftelse (TMS) in connection with Centre for Antimicrobial Resistance (CAMRIA). He is working on genetic features of gram-negative bacteria (particularly Klebsiella pneumoniae and Escherichia coli) that are linked to the propensity of Extended Spectrum BetaLactamase (ESBL) production. Clusters of genes features will be identified and fed through into hypercubic inference to learn and predict pathways by which AMR evolves in different regions and countries. Kazeem is also interested in advanced statistical learning, data science, and machine learning (supervised, unsupervised and semi-supervised learning). Papers with the group include EvAM and AMR, mBio 2025; Continuous-time accumulation, PLoS CB 2024; Mito-plastid evolution, MBE 2024.
