Aurora Early Science Program Postdoctoral Appointments

Postdoctoral Appointee – Aurora ESP Free Energy Landscapes of Membrane Transport Proteins
In this position, you will research and develop massively parallel codes for molecular dynamics of bio-molecular systems to facilitate computational simulations on extreme-scale supercomputing systems. The specific project involves membrane transport protein molecules that play key roles in cellular biology functions. This includes natural processes as well as drug delivery and drug resistance. How these “molecular devices” perform their function is extremely complex. The proteins move into dramatically different conformations in the process. Modeling the myriad possibilities with atomistic molecular dynamics, even using the best statistical approaches, is at the forefront of what’s possible. These massively parallel calculations will advance that front. If you have interest in this position, we invite you to apply for LCF Requisition #402073 by visiting Argonne's Career Page.

Postdoctoral Appointee – Aurora ESP High-Fidelity Simulation of Fusion Reactor Boundary Plasmas
In this position, you will research and develop massively parallel scientific codes that implement particle-in-cell methods for plasma dynamics. The specific project will simulate the behavior of plasma at the outer edge of a tokamak fusion reactor, an understanding of which is critically important to the success of future fusion reactors such as ITER, now under construction in France. This project will use particle simulations of the plasma, including impurities and the important magnetic field geometry at the edge, to predict behavior of ITER plasmas and to help guide future experimental parameters. If you have interest in this position, we invite you to apply for LCF Requisition #402074 by visiting Argonne's Career Page.

Postdoctoral Appointee – Aurora ESP Extreme-Scale Cosmological Hydrodynamic
In this position, you will research and develop massively parallel scientific codes that implement particle interaction algorithms, as applied to cosmology, and Lagrangian computational fluid dynamics methods (e.g. SPH) to evolve the hydrodynamic equations. The project focuses on large-scale cosmological simulations, including gravity and gas dynamics, using a new, smoothed particle hydrodynamics method. These simulations are deeply coupled with guiding and interpreting observations from present and near-future cosmological surveys.

Postdoctoral Appointee – Aurora ESP Extreme-Scale Unstructured Adaptive CFD
In this position, you will research and develop massively parallel scientific codes that implement scalable finite element based flow solvers and level set methods for turbulence simulations involving massively separated flows and two phase bubbly flows. The project involves using unprecedented high-resolution fluid dynamics simulations to model dynamic flow control over airfoil surfaces at realistic flight conditions and to model bubbly flow of coolant in nuclear reactors. The reactor fluid flow problems will simulate realistic reactor geometries with far more accurate multiphase flow modeling than today’s state of the art, yielding valuable information on thermal management to improve safety of existing light-water reactors and inform the design of next-generation systems.

Your work on this project will help to develop and extend the Uintah software framework so that it can simulate and evaluate the design of a next-generation, 500-megawatt advanced ultra-supercritical coal boiler. In a coal-fired power plant, this design promises to reduce the boiler footprint 50%, saving costs and improving efficiency (53% efficiency, compared with traditional-boiler 35% efficiency), and also reducing CO2 emissions by 50% relative to a traditional boiler. If you have interest in this position, we invite you to apply for LCF Requisition #402077 by visiting Argonne's Career Page.

Postdoctoral Appointee – Aurora ESP Metascalable Layered Materials Genome
In this position, you will research and develop massively parallel nonadiabatic quantum molecular dynamics (NAQMD) and reactive molecular dynamics (RMD) simulation programs. The specific project you will be working on is in the area of functional materials, which, as the name implies, have behaviors useful in science and industry. There is great interest today in engineering materials to have desired behaviors. One approach involves stacking atomically thin layers of different materials to achieve a complex molecular interplay throughout the stack. The resulting behavior of the stack cannot be explained by traditional theories and can only be predicted by directly simulating the layers as collections of molecules interacting with each other. Massive NAQMD and RMD simulations of functional layered materials will be validated by experiments on the same materials using a free-electron X-ray laser. If you have interest in this position, we invite you to apply for LCF Requisition #402078 by visiting Argonne's Career Page.

Postdoctoral Appointee – Aurora ESP Lattice QCD Calculations for Particle and Nuclear Physics
In this position, you will research and develop massively parallel lattice quantum chromodynamics codes. The focus of the project is to deliver calculations urgently needed by experimental programs of high energy and nuclear physics, based on the computational methods of lattice quantum chromodynamics (lattice QCD). QCD embodies our most fundamental understanding of the strong nuclear force and associated particles, a key component of the more general Standard Model of particle physics. In high energy physics, lattice calculations are required to extract the fundamental parameters of the standard model (such as quark masses) from experiment. Evidence for physics beyond the Standard Model can be discovered if discrepancies are found between different methods for determining these parameters. If you have interest in this position, we invite you to apply for LCF Requisition #402084 by visiting Argonne's Career Page.

The specific project will involve the flow of gases in extreme conditions, including shock waves and turbulence. This project aims to advance scientific understanding of variable density turbulence and mixing, including shock interactions and near-wall effects. These apply to the mixing of the fuel capsule surface with the imploding plasma in ICF, and shock interaction with fuel streams in a supersonic jet engine as a way to improve combustion. If you have interest in this position, we invite you to apply for LCF Requisition #402085 by visiting Argonne's Career Page.
