## The Ray Grimm Memorial Prize in Computational Physics Princeton University

This award was established in May 1985 by Cray Research, Inc. and friends of Ray Grimm, a pioneer in computational plasma physics at the Princeton Plasma Physics Laboratory and a long time mentor and professor in the Program in Plasma Physics. It provides a $5000 prize for an advanced (post-generals) graduate student at Princeton University who has demonstrated significant achievement in computational physics (such as is done in a number of departments at Princeton). In the event that two nominees are deemed deserving of this distinction, the award will be $4000 per recipient. If there are three awardees, the prize will be $3000 per student. Awardees for the past several years are:

**2014 awardees:**

**Junchao Xia** (Mechanical and Aerospace Engineering)

Advisor: Emily Carter

For his insightful development of ultrafast yet accurate quantum mechanics methods to simulate materials behavior at the atomic level through the mesoscale without use of wavefunctions and in terms of the electron density alone.

**Sonika Johri** (Electrical Engineering)

Advisor: Ravindra N. Bhatt

For original contributions to the physics of disordered and correlated electron systems, in particular the topics of Anderson Localization, Many-body Localization and the Fractional Quantum Hall Effect, using advanced computational techniques.

**Brendan Lyons** (Program in Plasma Physics)

Advisor: Stephen Jardin

For formulating and implementing an innovative method for incorporating intrinsically kinetic effects into magnetohydrodynamic calculations of magnetized plasma.

**2013 awardees:**

**William East** (Physics)

Advisor: Frans Pretorius

For pioneering general relativistic hydrodynamic simulations of eccentric black hole/neutron star mergers, ultrarelativistic particle collisions, and devising a new algorithm to efficiently model stellar disruption by supermassive black holes.

**Kevin K. Chen** (Mechanical & Aerospace Engineering)

Advisor: Clarence Rowley

For developing sophisticated methods for controlling fluid flows, including algorithms for determining the optimal placement of sensors and actuators, and improved techniques for extracting information from large datasets, that help reveal the fundamental flow physics.

**2012 awardees:**

**Adam Hopkins** (Chemistry)

Advisor: Salvatore Torquato

For his contributions to the field of computational physics that span from fundamental investigations of the structure and properties of particle packing problems, and their applications to glassy and crystal states of mater.

**Yan-Fei Jiang** (Astrophysical Sciences)

Advisor: James Stone

For developing, implementing, and testing advanced numerical algorithms for radiation magnetohydrodynamics on parallel high-performance computing systems, and for applying these methods to ab initio studies of magnetized accretion flows around black holes.

**Karthikeyan Rajendran** (Chemical and Biological Engineering)

Advisor: Ioannis Kevrekidis

For his ingenuous and innovative combination of modeling and scientific computing tools from nonlinear dynamics, multiscale modeling, optimization and uncertainty quantification with ideas from graph theory towards the model reduction of complex evolving network dynamics.

**2011 awardees:**

**Jayson Dean Lucius Peterson** (Program in Plasma Physics)

Advisors: Gregory W. Hammett and David R. Mikkelsen

For his studies of small electron scale plasma turbulence using a comprehensive gyrokinetic computer code and comparing with NSTX experiments, and for implementing and testing advanced algorithms to help improve such simulations.

**Robert Batten **(Chemical and Biological Engineering)

Advisors: Salvatore Torquato

For his contributions to the field of computational physics that span from developing new fundamental understanding of matter to providing guiding principles for the fabrication of designer materials.

**2010 awardees:**

**Chen Huang** (Physics)

Advisor: Emily Carter

For his breakthrough contribution to electron kinetic energy density functional theory and its implications for accurate large scale quantum mechanics simulations of materials.

**Yang Jiao**

Advisor: Salvatore Torquato

For his deep and penetrating contributions to the computational physics of heterogeneous materials and particle packing problems.

**Lin Lin** (Program in Applied and Computational Mathematics)

Advisor: Roberto Car

For his formulation of a new way of calculating the momentum distribution that is both numerically efficient and conceptually illuminating, and simply was not and could not be imagined before. His thesis will largely change the way we think about and perform electronic structure analysis.

**2009 awardees:**

Advisor: Clarence Rowley

**Sterling Smith** (Program in Plasma Physics)

Advisor: Steve Jardin
