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 ( 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.
