Career Profile
I am a palaeoclimatologist focused on the development and application of innovative statistical techniques based on the estimation and propagation of proxy natural uncertainties to reconstruct climate from extensive networks of fossil data. I am particularly interested in studying the spatial imprint of climate change in tropical regions on the centennial to orbital time scales. My research is oriented along the three following axes:
- Using proxy uncertainties to enhance fossil records. I believe that the natural uncertainties that pertain to all proxy data contain critical information that should be used to improve the representativity of each palaeoclimatic records in space and time.
- Integrating large compilations of fossil records. I am convinced that combining independent records together in dedicated frameworks can improve the signal-over-noise ratio of individual climate records. There is strength in numbers.
- Understanding climate drivers from tropical regions. I use a large array of state-of-the-art combined data-model assimilation approaches to shed light on the dynamical response of broad-scale climate drivers to past and future climate change.
Experiences
A member of the German consortium PALMOD, my role is to
- Coupling marine and terrestrial datasets
- Data-model comparison and/or integration
- Software developments
A member of the German consortium PALMOD, my role is to develop Bayesian statistical models to calculate the Bayes factor of temperature/precipitation reconstructions. Once develovelped, use of the tools to analyse the PALMOD transient climate simulations.
- Bayesian statistics
- Data-model comparison and/or integration
- Software developments
During this postdoc, I worked on a project focused on reconstructing Holocene climate across the Northern Hemipshere extratropics (Europe, North America, Russia) using extensive collections of fossil pollen data.
- Data compilation and curation
- Methodological developments
- Databases
- ‘Big’ Data Analysis
During this postdoc, I developed a relational database of climate records from Africa and implemented an R package to query and extract the data more easily.
- Databases
- Software development
During my PhD, I focused on developing new tools to reconstruct climate from pollen data and to employ them on southern African fossil records. I also created a point-and-click graphical interface to employ my novel statistical tools
- Methodological & Software development
- Data Analysis
- Synthesis and integration with climate models
