[ES_JOBS_NET] Two post-doc positions in soil biogeochemistry

[Erika Marín-Spiotta]

For the first
year, half of the position will
involve management of the NSF Research Coordination Network
(RCN) on Reactive
Nitrogen in the Environment.  The
other half of the first year and up to two
full additional years are to be dedicated to research on
developing the Dual
Arrhenius Michaelis-Menten (DAMM) model for soil carbon and
nitrogen dynamics
as part of a collaborative project with researchers from
Harvard University,
the USDA-FS, and the Woods Hole Research Center.  The DAMM model
will be integrated
with the Forest Biomass, Assimilation, Allocation and
Respiration (FöBAAR)
model, using data from an on-going project at the
Howland Forest of
Maine, applying data-model fusion techniques.  The model will also be
modified to integrate
CH4 and N2O uptake and efflux processes
with
decomposition and CO2 efflux simulations.  The ultimate aim of the
project is to improve
understanding of and modeling capacity for interactions of
belowground
temperature, moisture, and substrate supply from aboveground
processes as
controllers of net soil emissions of CO2, CH4,
and N2O.

Qualifications: A Ph.D. in biogeochemistry, ecology, or a closely
related field is
required.  The
successful candidate will
have a working
knowledge of C and N
cycling processes in terrestrial ecosystems.  Experience with
process-based quantitative
modeling, statistical analysis of large data sets, and
model-data fusion or
data assimilation is required.  Knowledge
of
at least one scientific programming language (ideally FORTRAN,
MATLAB and/or
R) is necessary, and experience using Bayesian approaches is
desirable. Willingness
to assist with team efforts at field work is expected.  Good writing and
communication skills are
essential.

*Postdoctoral Researcher in Biogeochemistry of Amazonian
Land-Use Change
*

The
post-doc will work closely with the PI on
a synthesis of studies regarding the effects of stoichiometric
ratios of C:N:P on
ecosystem productivity and land management sustainability across
an array of
forest (mature and secondary), pasture, and cropping systems in
the Brazilian
Amazon Basin.  The
objective of the
project is to ask from a biogeochemical perspective, what are
the key
components of sustainable land management in a matrix of land
covers?  The possibility
may exist for some additional
field studies, depending on further funding.

Qualifications: A Ph.D. in biogeochemistry, ecology, soil science, or
a closely related
field is required.  The
successful
candidate will have a
working
knowledge of C, N, and P cycling processes in terrestrial
ecosystems,
preferably with some experience in land-use change in the
tropics.  Experience
with process-based, quantitative
modeling is desirable.  Excellent
writing
and communication skills are essential.
