group leader
Thomas L.P. Couvreur (HDR)
Besides activities described on the homepage, I am active in taxonomical research in two wonderful plant families characteristic of tropical rain forests: Palms and Annonaceae. I undertake monographs and revisions of several little known genera in both families. I also write floras for both families for different countries. I work in herbaria and undertake field work for collecting plants in South America, Africa and South East Asia (see here). This last part is the basis of my research. Without taxonomy the above research projects would be hampered. Finally, I use the internet and special tools available to disseminate and make this information available to everyone (open access journals, scratchpad websites like World Annonaceae and Palms of Africa.
I am also Chair of the Species Survival Commission - Palm Specialist Group of the IUCN.

post doctoral researchers

Dr. Andrew Helmstetter
Andrew is working on the AFRODYN project. He is undertaking comparative phylogeographic analyses of several Central African rain forest plants using NGS and targeted exon sequence capture.
​Andrew's research broadly aims to understand the evolutionary origins of diversity. He uses phylogenetic and population genetic approaches to answer questions related to evolutionary processes with applications in the fields of plant health and conservation.

phd students

 Suzanne Kamga Mogue (co supervised by Prof. Bonaventure Sonké)
Université de Yaoundé I
2015-2018
​
Suzanne is doing her PhD on the socio-economic importance and taxonomy of the palm genus Raphia within the RAPHIA project.
Ariane Cosiaux (IRD) 
Ariane’s main interest lies in understanding the relationships between humans and environment, more specifically humans and plants. Based on an ethnoecological approach, she is undertaking a PhD focusing on the historical dynamic of the uses and management of the palm species Raphia mambillensis, in the western Highlands of Cameroon. The species is a key component across the landscapes of the region, and it is widely used (e.g. household uses, ritual uses). However, the uses and the ways it has been managed overtime are not well understood, as well as the origin of its distribution across the region.
Ariane is also working on Red Listing palms of Africa. Here is one of her recent articles:

Amoussou Biowa Eldys Narcisse (co supervised by Romain Glèlè)
​Universite de Abomey Calvi & Universite de Montpellier.
​2017-2020

Eldys works on the impact of climate change on several important non timber forest products (NFTP) across Africa. He uses species distribution modeling and future climate change scenarios infer to impact for global change on species distributions and the economical impact these changes will have.
Sebastían Pablo Escobar Vasquez (Co supervised by Henrik Balslev, Rommel Montufar)
Aarhus University
​2017-2020

Sebastian studies the evolutionary dynamics, population genetics and dispersal ecology of Phytelephas aequatorialis, also known as tagua. This is a dioicious palm endemic to western Ecuador and exploited for its "vegetable ivory".  Sebastian is based in Aarhus, but will spend significant time in Ecuador for field work and Montpellier for lab work.

undergraduate students

Leo-Paul Dagallier
Master 2 student, Universté de Montpellier
2018
​
Leo Paul's thesis focuses on exploring the phylogenetic patterns of tropical African biodiversity, based on the RAINBIO database, and using a large phylogeny of African plants. He will in particular try to identify areas of paleo- and neo- endemics at the continental level.
