Martin Lascoux

MartinLascouxPortrait I am a professor of population genetics at the Evolutionary Biology Centre, Uppsala University. Over a period of five years (2009-2014) I have shared my time between Uppsala and Shanghai where I worked at the Chinese Academy of Sciences (PICB, together with Li Haipeng) and at Fudan University (together with David Waxman).
I primarily work on plant species, and more specifically on forest trees (spruces, birches, larches, poplars) and weeds (Capsella bursa-pastoris and its relatives). I have been working on an array of issues revolving around the interaction of the different evolutionary forces, in particular the interplay between demography and selection in shaping genetic diversity. Lately I have been especially interested in question related to the genetic basis of local adaptation. When addressing evolutionary questions we  are using an array of techniques, including genomics, growth chamber experiments and field experiments. Although not a theoretical population geneticist myself I have  been collaborating closely with some of them over the years.

Associated Researchers:

Sylvain Glémin

Sylvain I’m a research director at the French CNRS and was a visiting researcher at EBC during four years. I am now back in France but still associated to the group. My works concern theoretical population genetics and evolutionary genomics. I use population genetics modeling and sequence data analyses approaches, mainly in plant species. My current research topics are:
– The evolution of mating systems and their genomic consequences
– The evolution of GC content in plants and the role of GC-biased gene conversion
– The genetic and genomic of plant domestication
– The consequences of life-history traits on molecular evolution

Postdoctoral Fellows:


Mathieu Tiret


imageI am a postdoctoral researcher at EBC since Nov. 2019, with a background in population genomics and quantitative genetics. I work on genomic selection in forest tree breeding, and it is the second European project I am working in (Gentree and B4Est). My first research topic was finding the right balance between selection and diversity in the breeding program of Populus nigra, to maintain long-term genetic gain. Nowadays at the EBC, I study group selection in the context of forest tree breeding. The twofold purpose of this project is 1) to improve stand performance by accouting for within-species competition and plasticity to neighbouring, and 2) to enhance resistance to parasites by maintaining high level of genetic diversity.


Zhang Zebin

Arriving in July 2020. Zebin will work on the evolution of  polyploidy using Capsella bursa-pastoris as an experimental system.

PhD students:

Lili Li

Lili_LiAfter working on the population demographic history of Picea schrenkiana during my Master at Lanzhou University, I continue to study spruce species, but I now mainly focus on the population genetic structure and local adaptation of boreal spruce species. Intraspecific latitudinal clines in genotypes and phenotypes are widely interpreted as basic evidence for natural selection and adaptation to local environment. Two parallel latitudinal clines in gene expression and allele frequency have been detected in Norway spruce (Picea abies) and Siberian spruce (Picea obovata).  However, the coverage of high latitude populations was insufficient in the previous study of Picea obovata. So we added samples from populations higher higher latitudes, to test for clinal variation.

Luis Leal

Luis Leal PhD student UppsalaLuis is currently studying Nordic birch populations in order to map their adaptive response in the face of global climate change. Over 50 different birch species can be found along the Eurasian continent, often living in sympatry, their evolutionary histories interwoven by common selective forces and recurrent hybridization and introgression events. We will be looking into three birch species present in Sweden – silver, downy, and dwarf – and use genomic data collected along a latitudinal cline to investigate the roles played by hybridization, selection, and population demographic history in shaping local adaptation.

Before joining Martin’s group, Luis worked with Niclas Backström at the Department of Ecology and Genetics, Uppsala University, where he used gene expression profiling to identify genes and pathways underpinning diapause regulation in wood-white butterflies.

Tianlin Duan

Tianlin is a second year PhD student working on gene expression pattern in neopolyploids Capsella. During her first years she created a series of neopolyploids and she is currently carrying the RNASEQ part of the project. She is also working on the origin of the tetraploid C. bursa-pastoris, and in particular try to tell apart multiple origins from secondary contact.
