Scientific investigations


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.


Objectives

How has the structure of Eurasian woody forests changed during the last million years and what are the factors involved in these changes?

Setting up robust collaboration work between European, Iranian and Chinese teams


How herbivory traces on leaves are a robust indicator of those forest structure changes?

Gathering (and photography) as maximum as possible fossil leaf collection from museum


What is the biogeographical history of the genus Parrotia ?

Currently, development of the project "PARROTIA", website coming soon.

In the fossil record, it is quite impossible to distinguish different environmental conditions where plant species identifications are similar; herbivory traces are a major asset for such kind of problem.

Teaching



I teach sciences to young people with my experiences in scientific animations, and sure to students in their bachelor’s and master’s degrees. The majority of my teaching at University deals with animal and plant biology by focusing on the main concepts of evolution and ecology. Geology is also include in my skills for teaching.
