MODELLING STOCHASTIC PROCESSES FOR FORESTS – CLIMATE INTERACTIONS

BACKGROUND: We are seeking a RESEARCH ASSOCIATE (PhD or postdoctoral) to i) 
further develop a process-based global land surface model (ORCHIDEE) used 
within the IPSL Earth system model for climate simulations (IPCC-AR5) and ii) 
strengthen a recently established ERC research team (2 post-docs, 2 PhD's and 1 
PI) that aims to quantify and understand the role of forest management in 
mitigating climate change. To this aim, the team is working towards a more 
detailed and process-based description of forest stands in ORCHIDEE and wants 
to start developing a model-module that bolts together earlier developments. 
This module will implement a computational efficient scheme to model stochastic 
processes (i.e. gap dynamics) and the resulting multi-layered canopy structure. 
A similar scheme called SAS has been proposed by Mooncroft et al 2001. A method 
for scaling vegetation dynamics: the ecosystem demography model. Ecological 
applications, 71(4):557-586.

HOME INSTITUTION: Laboratoire des Sciences du Climat et de l'Environnement 
(LSCE, Orme-les-Merisiers, Gif-sur-Yvette). LSCE is a joint research unit of 
Commissariat à L’Energie Atomique et des Energies Alternatives (CEA), Centre 
National de la Recherche Scientifique (CNRS) and Université de Versailles Saint 
Quentin-en-Yvelines (UVSQ). LSCE employs over 320 researchers covering 30 
different nationalities. Their research mission is to contribute to a better 
understanding of the interactions between human activities in the Earth System, 
environment and climate dynamics at different time scales. LSCE is a world 
class institute and a thriving nexus for climate change research.

DESCRIPTION OF RESPONSIBILITIES: The major focus of the position is placed on 
research and code development. The successful candidate will reinforce and 
widen the expertise of the team while strengthening synergies within the LSCE. 
Research duties include all of the following: literature study, model 
development (ORCHIDEE land surface model), data processing, and model 
validation (ORCHIDEE), participation in scientific conferences and publication 
in peer reviewed international journals. The position is available for up to 24 
months (with a likely 1 year extension).

QUALIFICATIONS: Given the interdisciplinary nature of the research we are 
seeking for a highly motivated individual with a degree (Master or PhD) in for 
example mathematics, physic, engineering, computer science, meteorology or 
theoretical ecology. A broad interest in natural sciences more specifically 
forest ecology is essential. Rather than for a specific training, we are 
looking for a candidate who is able to demonstrate her/his ability to develop 
code (Fortran 90), solve (partial) differential equations and solve numerical 
schemes. Priority will be given to individuals who published peer-reviewed 
papers but it is not a strict requirement.

REQUIRED CONTENT OF THE APPLICATION

There are no specified application forms. Applications and inquiries should be 
sent to Sebastiaan Luyssaert 
(Sebastiaan.Luyssaert@lsce.ipsl.fr<mailto:Sebastiaan.Luyssaert@lsce.ipsl.fr>). 
Applications should include (1) a curriculum vitae, (2) statement of 
motivation, (3) a short description (½ page no more than 1 page) of a recent 
problem you successfully solved making use of differential equations (or other 
advanced mathematical tools) and (4) names, addresses, phone numbers, and email 
addresses of at least two references. The position is immediately available and 
will remain open until filled with review of applications and interviews 
starting on October 21st. Salary follows national directives and is adjusted 
for work experience. A dual position may be explored in case the partner has a 
competitive cv and background in line with the research activities at LSCE.
