A postdoctoral position is available immediately at the University of Pittsburgh, Department of Chemical Engineering, under the direction of Prof. Karl Johnson (http://puccini.che.pitt.edu/).  This position is funded by a grant from DARPA (http://www.darpa.mil/) and is in collaboration with experimental groups at Teledyne (http://www.teledyne.com/) and at Virginia Tech with Prof. Eva Marand. The research program involves modeling transport and selectivity of aqueous mixtures through carbon nanotube/polymer mixed matrix membranes.  The successful candidate will be highly motivated, be able to work independently, have extensive experience in modeling complex molecules in aqueous environments, have a working knowledge of transport phenomena, including transport of ions in aqueous solutions, and expertise in molecular dynamics and Monte Carlo methods.  Extensive experience with performing large-scale molecular dynamics simulations and proven ability to write computer code (FORTRAN and C) are required.  A working knowledge of quantum mechanics and familiarity with packages such as Gaussian 03 is a plus. The candidate should have a Ph.D. in chemical engineering, physics, chemistry, materials science, or a related field.  Qualified candidates should send a resume and a brief description of research accomplishments in PDF format to karlj@pitt.edu along with names and email addresses of three references.  The position is initially for one year with the possibility of renewal based on performance and funding availability. A very competitive salary and benefits package is offered through the University of Pittsburgh.
