My group combines mathematics, computer simulations and genomic information to study evolutionary processes. We aim to understand how a tumour's evolutionary history is reflected in its genome, how evolution can be quantified in individual tumours and how this information predicts future evolution.

Quantitating somatic evolution in cancer

Tumours have tremendous intra-tumour genetic heterogeneity. We do now understand that a stochastic somatic evolutionary process of mutation accumulation and selection can explain these patterns. However, it remains difficult to quantify these evolutionary forces within individual tumours. One of our main goals is the development of methods that can explain and quantitate these processes. To do so we combine mathematical descriptions of somatic evolutionary processes and cancer genomic data.

Theoretical Population Genetics

An important aspect of our work is to develop new theoretical tools rooted in population genetics. We often combine stochastic branching processes and individual based computer simulations to explain and quantitate somatic evolutionary processes.

Resistance Evolution and Treatment Strategies

Exciting new cancer treatments are developed continuously e.g. novel targeted therapies or Immunotherapy. Unfortunately, emerging treatment resistance remains a major challenge. Our aim is to quantitate the process of resistance evolution within single patients. We use ctDNA (cell free tumour DNA) to follow resistance evolution over time, which allows us to forecast relapse times, providing a treatment window of opportunity.

Stochastic Dynamics of Extra Chromosomal DNA Elements

Recent studies have identified extra chromosomal DNA elements (ecDNA) to contribute to tumour evolution and resistance emergence. These elements have a random pattern of inheritance and thus the stochastic dynamics of these elements differs greatly from standard somatic evolutionary dynamics. We develop a theoretical understanding of these dynamics and test these predictions in patient data.

Predator-prey co-evolution

We also have an interest in non-somatic evolutionary processes, in particular, co-evolutionary processes of interacting species and the resulting stochastic dynamics. Our lab has been involved in co-evolutionary experiments in predator-prey systems. Questions involve the understanding of the emergence and maintenance of diversity as well as the interpretation of complicated population genetics data under co-evolutionary processes.

Biography

After I received my Diploma in Physics from the University of Leipzig in 2010 (Germany), I started my PhD (2010-2013) with Arne Traulsen in the Evolutionary Theory Group at the Max Planck Institute for Evolutionary Biology, where I mostly worked on mathematical models of cell population dynamics. I then continued for a brief Post Doc with Arne (April 2013 – January 2015) to work on the dynamics of haematopoietic stem cell and telomere shortening during ageing.

In 2015, I moved to London to become the first Post Doc in the Cancer Evolutionary Genomics & Modelling Group of Andrea Sottoriva at the Institute of Cancer Research. In the next 4 years we worked on many aspects of somatic evolution, with the overall theme of how to combine evolutionary theory and cancer genomic data.

In October 2019 I joined the newly established Centre of Cancer Evolution and Computational Biology at the Barts Cancer Institute to establish my own research group on Evolutionary Dynamics.
