Dear All,

My apologies in advance for a misuse of this list.  However, I wanted to
draw your attention to a new postdoctoral position at Argonne National
Laboratory, which may be of interest to some of you. This job involves
research into efficient algorithms for numerical modeling and simulation of
solutions of charged particles in confined geometries. Experience with
PETSc, libMesh or MOOSE will be a big plus here, hence, this message.

The formal position description can be found here:

In plainer terms, however, we are interested in the quantitative
understanding of the dynamics of DNA molecules suspended in solutions of
varying ionic strength, and confined to channels of 10-100nm linear
cross-section, with charged walls.  If you know your way around FEM models
of Stokesian fluids in nontrivial geometries, have experience with
electrostatic force calculations, and are interested in making these
algorithms run fast, this may be the job for you.

We are interested in accelerating these simulations to be able to resolve
the long-time fluctuation dynamics of the DNA molecules translocating
(i.e., flopping their way through) the nanochannels. Some modeling issues
will likely need to be addressed as well: at various ionic strengths the
finite-size effects of ions in the solution may become significant near the
channel walls or the solute (DNA) molecules. Thus, an interest and
experience in particle-to-continuum coupling is a plus.

A working knowledge of C/C++ is required. Familiarity with the
GPU/multicore/manycore architectures is preferred. Experience with the
PETSc library (http://www.mcs.anl.gov/petsc) is a huge plus.  Ditto libMesh
and MOOSE.

A successful candidate will work closely with the University of Chicago
scientists at the Computation Institute as well as the Institute for
Molecular Engineering.

If you have questions, please feel free to contact me directly.
I apologize, if you are getting this message more than once.

Best regards,
