Welcome to my (minimal) scientific homepage - Toni Ingolf Gossmann

I am a researcher in the field of evolutionary biology. I work on different topics that are all connected by my passion for knowledge and creativity. At the moment I am at the University of Sheffield as a Leverhulme Early Career Fellow.


Research Interests

(1) Recombination rate variation and Hill-Robertson Interference in the great tit (Parus major) genome

A special feature of birds is the very high karyotype conservation and heterogeneity in chromosome size causing substantial variation in recombination rate between chromosomes. The great tit (Parus major) has a large, panmictic population, making it an ideal system to study genome-wide patterns of recombination rate variation and its effects on patterns of polymorphism and divergence. I am using a fine-scale recombination map to scan the great tit genome for traces of positive and purifying selection to illustrate how recombination has facilitated the action of natural selection due to Hill-Robertson-Interference.


(2) The role of positive and negative selection in the plant genome of Arabidopsis thaliana

Arabidopsis thaliana is a model plant species and its natural habitat is Eurasia and North Africa. It was the first plant genome ever sequenced and as a part of the 1001 genome project a large number of accessions have been sequenced. This data can be used to address a manifold of questions - I am interested in two in particular - first, what is the long term impact of whole genome duplications in Arabidopsis thaliana and second, what are the evolutionary forces that have shaped patterns of diversity and divergence in reproductive genes.

(3) Evolution of NAD metabolism

NAD (Nicotinamide adenine dinucleotide) is one the most prominent cofactors and involved in thousands of redox reactions. However, recently it has gained increased attention for its substrate role in signalling, DNA repair and protein regulation. Together with my collaborators at the University of Bergen and University of Jena we investigate evolutionary patterns that have shaped the diversity of NAD biosynthesis and consumption in humans and other eukaryotes.

(4) Selective forces acting in natural populations and theoretical population genetics

I also focus on theoretical questions of population genetics. The major underlying concepts of population genetics have been established from the thirties to seventieth of the last century. However, clearly there is a need to refine the theoretical models when applied to data as mathematical assumption usually turn out to be too simplistic. I have been involved in multiple projects targeting such refinements, for example by quantifying the variation of the effective population size within a genome and the effect of fluctuating selection on tests of positive selection. I also investigate the role of background selection in shaping diversity in a framework of varying recombination rate and demographic change.
