In 2018, I obtained my PhD co-diploma in Environmental Sciences and Paleobiology within Bonn University (Germany) & University of Montpellier (France).
Today, my aim is to focus on forest trophic structures change over the time based on a multi-disciplnary approach, which plant-insect interactions is spearhead my research.
- Plant-insect interactions
For such research, paleontological data from the millions of years are crucial in order to better understand the dynamics of ecosystems and their changes due to abiotic and biotic factors. Main data measured are herbivory traces that we can easily observed on the leaf blade in both fossil and modern records. Herbivory patterns are the representation of a large part of the ecosystem activity, their variations are dependent on a wide range of parameters which affect the host plant on the one hand and the herbivorous insect on the other.
My working line is about Eurasian temperate ecosystems evolution in the Cenozoic, until present. Both fossil and modern material are involved into my researches. In addition to my specialization to work on leaves (insect trace damage, morpho-anatomy, species identification, climate reconstruction), I extended my work with others types of proxy such as pollen, luminescence imaging, specific focus on global ecology for endemic plant species which constitute another main part of my work now (see below).
- Relict and threatened woody plant taxa
To understand and characterize environmental changes over the time, to focus on some specific species is also an important point. Furthermore, such approach is also an interesting approach in order to alert public opinion on global change.
Currently, this part of my work is mostly focusing on Genus Parrotia.
Parrotia is compound by two plant species.
Parrotia persica C.A.Mey, endemic of the Hyrcanian forest (Iran, Azerbaijan).
Parrotia subaequalis (H.T. Chang) R.M. Hao & H.T. Wei, endemic of the eastern China (Jiangsu, Zhejiang, Anhui, Henan provinces).
Those species spread across a huge part of Eurasia (from at least Spain to Japan), but nowadays due to the introduction of glacial/interglacial cycles (from the late Cenozoic) both of those species became endemic into two different relict forest. P. persica is endemic of the Hyrcanian forest (Iran, Azerbaijan) and there is some small population of P. subaequalis in the eastern part of China (Jiangsu, Zhejiang, Anhui, Henan).
In fossil record, those species are very important as they often significantly contribute to estimate paleoclimate and are helpful to describe environnemental changes.
I focus on the biogeography history of Parrotia throughout several proxy such as pollen, leaf morphology, plant-insect interactions, population genetics, etc.
