I am a CNRS research director at the Institute of Biology of the Ecole Normale Supérieure. I am also associated to the SMILE group at the Collège de France. I am broadly interested in biodiversity research, and I am a TED Fellow.

Caitlyn Jean-Baptiste
I am a graduate student at Sorbonne University. I am interested in biodiversity, genetics and evolution. I joined the lab for my final year internship and I am working on the collection of genomic and protein sequences for the collaborative project "Quantitative Tools for assessing the Correlated Evolution of Genes and Phenotypes: Application to Birds Color Patterns (Q- T-Birds)".

Abdelmajid Omarjee
I am a graduate student at Paris-Saclay University, completing a master’s degree in evolutionary biology and genetics, with a background in bioinformatics. My interests focus on how evolutionary history shaped today’s living organisms and their ability to adapt to current environmental pressures. For my internship, I am trying to specify how microevolutionary proceses scale up to the dynamics of phenotypic traits evolution at the macroevolutionary scale.

Viktor Senderov
I joined the lab in October 2022 for my third postdoc. My first two were with Fredrik Ronquist and David Broman in Stockholm as part of a Marie Curie-funded project aiming to develop a new universal probabilistic programming language for phylogenetics named TreePPL. My new project here in collaboration with Amaury Lambert and Marie Manceau aims to develop Bayesian probabilistic models for the co-evolution of molecular and phenotypic traits as applied to bird genomic data.

Pierre Veron
I graduated from the École Polytechnique and the EPFL, master Environmental Sciences. After a master thesis at Ifremer on fish biodiversity, I joined the lab in October 2022 for a PhD on speciation modelling, co-supervised by Hélène and Tatiana Giraud. I am interested in understanding how microevolutionary phenomena explain speciation rate heterogeneity.

Lucas Buffan
I am a student at the École Normale Supérieure de Lyon, with a background in biology and complex systems modelling. My interests are related to understanding the environmental drivers of biodiversity changes across space and time. For my internship in the lab, I am reconstructing the palaeodemographic trends of planktonic diatom populations to infer their link with past biotic and abiotic changes.

Nils Chabrol
I am a 4th-year student at the ENS de Lyon. I have a master's degree in Palaeontology, Sedimentology and Palaeoenvironments but I have been able to follow courses in ecology, bioinformatic and evolution. My research interests are mainly paleontology, macroevolution and informatic approaches in these fields. I joined the lab last September for a 5 months internship on developing a fossilized version of the diversification model "ClaDS".

Renan Maestri
Renan is an evolutionary macroecologist from Universidade Federal do Rio Grande do Sul. He is a post-doc in the lab, funded by the One Health MOPGA program. He is working on the macroevolutionary and biogeographic association between mammals and coronaviruses..

Joelle Barido-Sottani
Joëlle joined the lab in November 2021 as a Marie-Curie fellow. She is broadly interested in developing and implementing birth-death models for Bayesian phylogenetic inference, in order to understand better the underlying processes which give rise to phylogenetic trees. In particular, she contributes to the software frameworks BEAST2 and RevBayes. Her current research focuses on models with lineage-specific variation in birth and death rates, and their use in full phylogenetic inference.

Jérémy Andréoletti
Jérémy is a student from the Ecole Normale Supérieure, Masters IMaLiS at the ENS and Mathematics for Life Sciences at the Université Paris-Saclay. Interested in the evolution of biodiversity and its links with environmental drivers, he previously did an internship in the lab and is now doing a PhD on the extinction drivers of microeukaryotes, co-advised by Erin Saupe.

Octavio Jimenez Robles
Octavio is an avid field naturalist with a research background in community ecology, biogeography, natural history, and ecophysiology. He is a Marie Sklodowska Curie Fellow working in collaboration with Craig Moritz at the Australian National University. His project tackles the impact of biotic interchanges on diversification using phylogenetic and macroevolutionary approaches.

Ignacio Quintero
Ignacio is broadly interested in studying variation in biodiversity from an evolutionary perspective. Specifically, he uses and implements phylogenetic tools, such as inference of diversification rates, trait evolution, and phylogeography, to gain a more mechanistic understanding on the origin of diversity patterns. He joined the lab as a post-doc in January 2019, funded by the ERC grant PANDA. He is now funded by his own Marie-Curie fellowship INSANE.

Benoit Perez
Benoît is a PhD student from the Ecole Normale Supérieure and now post-doc in the lab. Interested in the interactions between complex organisms and their unicellular symbionts, he is working on models of coevolution between hosts and microbiota. He is a student from the Master IMaLiS at the École Normale Supérieure and the Master Ecology, Biodiversity and Evolution at the Université Pierre et Marie Curie.
Visitors

Wenna Ding
I am a postdoc fellow at the Swiss Federal Research Institute WSL and funded by SNSF Swiss Postdoctoral Fellowship to work with Niklaus E. Zimmermann in collaboration with Hélène. I am interested in the biotic interchange among different mountain ranges in the Northern Hemisphere and how historical factors (e.g., uplift and climate changes) have affected the alpine plant diversification.

Michael Turelli
Michael is on sabbatical from the University of California, Davis. He will be spending three weeks in the lab this September.

Alfried Vogler
Alfried Vogler is on sabbatical from Imperial College London and the Natural History Museum. He studies the phylogenetics and diversification of the Coleoptera (beetles). He is compiling an increasingly complete tree that integrates all available genome sequences, phylogenetic markers and (meta)barcoding. His visit is funded by the Leverhulme Trust. He is part of the iBioGen project.

Romain Watteaux
Romain is a postdoctoral researcher at the Statione Zoological Anton Dohrn in Napoli. He is currently hosted in Hélène's group. Romain studies how fluid dynamics affects growth and distribution of plankton in the oceans. He is a collaborator of Guilhem's study of drivers of community assembly in the eukaryotic plankton.

Gisela Kopp
Gisella is a postdoc fellow in the Max-Planck-Institute for Ornithologie. She obtained funding to come in Paris for several visits. Gisella is interested in understanding how behaviour, such as spatio-temporal grouping patterns and dispersal, impact genetic diversity and evolutionary processes, such as local adaptation, genetic differentiation, and speciation.

Marius Somveille
Marius is a postdoctoral fellow of the Edward Grey Institute at Oxford and visits the lab regularly. His research interests lie in understanding the processes underlying biodiversity patterns. In particular, his work focuses on the macroecology and macroevolution of bird migration.
