March 2019 – The whole happy yeast bunch
Rike Stelkens (Group Leader)
I am an evolutionary biologist interested in the generation and the maintenance of biodiversity. I study the effect of genetic exchange between populations and species on adaptation to environmental change. I have a fishy background but have now converted to the awesome power of yeast genetics.
Claire Brice (Postdoc)
Claire is a microbiologist and biotechnologist interested in understanding genetic adaptation to changing and stressful environments. She is currently running fitness assays in environmental gradients, using various interspecific yeast hybrids.
Zebin Zhang (Carl Trygger Postdoc)
Zebin is a bioinformatics analyst and molecular biologist. He is currently working with RADseq and long read seq data from interspecific yeast hybrids. His aim is to understand how hybrid genomes are assembled and selected under environmental stress, testing predictions of quantitative genetics with a special focus on epistasis. Zebin is also interested in the adaptive value of ploidy variation, and in detecting signatures of domestication in the genome.
Devin Bendixsen (Wenner Gren Postdoc)
Devin is a bioinformatician specialising in computational genomics and empirical fitness landscape construction and analysis. His current research interests range from mutational interactions and their effect on mutational pathways to genetic mechanisms underlying evolutionary adaptation. He is currently focusing on understanding the role of hybridization in genetic adaptation to novel environments using lineage tracking in yeast strains.
Ciaran Gilchrist (PhD student)
Ciaran’s PhD focuses on comparing the risks and benefits of hybridization for adaptation to changing and stressful environments. The yeast populations he is evolving in divergent environments have now reached >500 generations!
Alexandre Rêgo (PhD student)
Alex’s interests lie broadly in evolutionary biology and population genetics. His PhD research uses experimental evolution to describe the origin, dynamics, and outcomes of adaptation to novel environments. He is currently working on understanding how different sources of genetic variation shape the dynamics of adaptation.
Maria de la Paz Celorio Mancera (Researcher)
Maria is a part time researcher in the group, managing the lab and the sequencing.
Julie Grosse-Sommer (BSc student)
Julie is a BSc student from Maastricht University doing the lab work for her thesis in our lab. She measures fitness and runs direct competition assays between the strains coming out of Ciaran’s long-term evolution study.
Viktoria Köppa (internship student)
Viktoria is a student from Stockholm University doing an internship in our lab. She is fine tuning simple and complex stress environments and dissecting the tetrads of divergent yeast crosses.
