After a PhD in cognitive neuroscience, I joined the CEFE to work with Julien Renoult whilst collaborating with Tamra Mendelson (UMBC).

The idea of my postdoc is to use artificial neural networks to create novel stimuli that mimic natural statistics. We will conduct experiments in the rainbow darter fish (Etheostoma caeruleum) to investigate the evolution of pattern preferences and signal design (efficient coding framework).

I am also interested in scientific practices and making our research more reliable, and I am always happy to talk about those questions. Feel free to reach out!

I am a behavioural and evolutionary ecologist interested in understanding why individuals behave in the way they do and the ultimate fitness consequences and proximate mechanisms of those behaviours.  I am keen on exploring the causes that generate individual variation in behavioural traits in the animal kingdom, regardless of the target species. Further, I also have a deep interest in exploring how individuals adapt to the fluctuating environmental conditions and the fitness consequences of the different life-history strategies present under those variable conditions.

Currently, I am working in the team of Claire Doutrelant studying the role and the evolution of the multiple signaling systems in birds. We aim to that by doing experiments in the wild and by analyzing long-term datasets using the blue tit (Cyanistes caeruleus) as a model species. Further, we will also explore this topic in a broader fashion by conducting a comparative analysis.

Potentiel adaptatif en milieu urbain : une étude chez la mésange charbonnière

Adaptive potential in urban habitat : a case study in great tits

 

Durant mon projet de thèse je m'intéresse à l'impact de l'urbanisation sur les espèces sauvage. Pour cela j'utilise la mésange charbonnière (Parus major) comme modèle biologique. Mes objectifs sont :

  • Comprendre comment les nouvelles conditions environnementales présentes dans les villes (pollution, dérangement humain, artificialisation...) affectent les mésanges urbaines.

  • Déterminer si la mésange parvient à s'adapter au milieu urbain suite à des pressions de sélection naturelles modifiées 

  • Comprendre l'impact de la vie en milieu urbain sur l'épigénomique

 

My PhD project aim to understand the impact of urbanisation on wildlife. To do so I use the Great tit (Parus major) as biological model. My main objectives are :

  • Understand how great tit are affected by city's new environmental conditions (pollution, human disturbance, artificialisation...).

  • Determine if great tit is adapting to urban habitat in response to new selection pressures. 

  • Understand the impact of city life on epigenomic processes.

Research Interests

My interests can broadly be defined as evolutionary ecology in different aspects. I am particularly interested in anthropogenic impacts on host-parasite interactions, such as changes in habitat and climate change.

My postdoctoral research focused on two main projects. One was on the evolutionary strategies of malaria parasites among different bird host communities across Africa. With environmental changes, we anticipate a change in the distribution of both specialist and generalist parasites with potential impacts on bird communities.
My second project focused on global climate change and spread of malaria in Alaska. As a comparison with tropical regions, we wish to determine how climate change can also affect parasite transmission in Arctic regions since the main prediction is that malaria parasites will spread to both higher altitudes and to northern latitudes with global warming. For this project, I also studied vector ecology that plays a crucial role in the spread of avian blood parasites.

Understand how ecological changes affect the prevalence, distribution and strategy of specialization of parasites is an important challenge both in terms of the ecological consequences of the dynamics of the interaction between the host and the parasite as well in terms of conservation.
