Iain Johnston (Group Leader)

Iain is a Professor in the Faculty of Mathematics and Natural Sciences 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

Kazeem 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).

Robert Glastad

Robert is a PhD student funded by the University of Bergen. He is combining metabolic and stochastic modelling to explore the interplay between physical, genetic, and metabolic dynamics in the mitochondrial populations of cells. Robert's papers with the group include: Avoiding organelle mutational meltdown (PLoS Biol 2021).

Belén García Pascual

Belén is a PhD student in the ERC EvoConBiO project. She works with mathematical models to explain gene retention by organelles throughout evolutionary history, together with multi-scale biological systems. She has a bachelor in Mathematics from Complutense University of Madrid and a master in Topology from the University of Bergen, so she is also interested in the applications of algebraic geometry and topological data analysis in cellular biology.

Rajneesh Kumar

Rajneesh is a PhD student funded by UiB. Following a BSc in maths (Delhi) and MScs in applied maths (IIT Mandi) and oceanography (Southampton via the Commonwealth Scholarship scheme), he is studying the causes and influences of heterogeneous energy supply in cell and evolutionary biology, capturing the dependence of life's essential process on ATP. His research uses models and simulation to explore how ATP variability arises within and between cells, and the consequences of this behaviour for cell biology, population dynamics, and the evolution of co-operation and competition.

Jessica Renz

Jessica is a PhD student in the CAMRIA HyperEvol project. After completing her BSc and MSc in Mathematics at the University of Stuttgart, as well as a degree in biology as part of a teaching programme, she is working now with hypercubic models to learn and predict the evolutionary pathways of antimicrobial resistance. In her research she is interested in understanding those evolutionary processes with the help of models both from a statistical point of view, but also with the help of pure mathematics like algebra and geometry.

Olav Aga

Olav is a medical student investigating how bacteria acquire multidrug resistance. His current focus is inherent evolutionary mechanisms in Klebsiella pneumoniae. He is interested in how methods developed in the research group can be applied in the clinic. Olav is developing an R-library enabling clinicians to use hypercubic inference tools. Before studying medicine, Olav completed a bachelor's degree in informatics at the University of Oslo. He is enrolled in the Medical Student Research Programme at UiB and is currently doing a full-time year of research based at the Computational Biology Unit.

Fábio Dias Correia de Oliveira

Fábio completed his bachelor's in physics from the University of Porto. Afterwards he continued his studies by taking a master's in biological physics and computational biology at Lund University. Now he is doing a master's in statistics at the University of Bergen. He is generally interested in evolutionary questions and for his master's project he is working with the hypercubic model.
