Reseach Software Engineer - Ice Sheet Model Team @ ACCESS-NRI/Monash University

Acton, Australian Capital Territory, Australia

About

I am working as a Senior Research Officer in the Ice Sheet Modeling Team at the National Research Infrastructure for ACCESS (Australian Community Climate and Earth Systems Simulator), Australian National University (ANU). I am also currently working on research in theoretical and numerical gas and plasma dynamics, fluid structure interactions and CFD (Computational Fluid dynamics) in the department of Nuclear Physics, Research School of Astronomy and Astrophysics and the Mathematical Sciences Institute. For more details about the work, you can refer below to my Orcid, google scholar, etc., below, as well as in the experience section. Google scholar: https://scholar.google.com.au/citations?user=FGfPj-4AAAAJ Orcid: https://orcid.org/0000-0002-5238-6115 Here is where you can access some of my codes and forks, I do most of my code development via Github: Google scholar: https://scholar.google.com/citations?user=FGfPj-4AAAAJ&hl=en My public github repos: https://github.com/justinh2002 ANUFoam private repo: https://github.com/justinh2002/ANUFoam Bitbucket: https://bitbucket.org/justinh2002/ My main interests are numerical methods for nonlinear PDEs, shock wave reflections, and hydrodynamic and MHD turbulence theory for astrophysics and engineering. I am very interested in shock-turbulence interactions, high-order discretisation of hyperbolic PDEs using finite difference, finite volume and pseudo-spectral methods, and analytical closure models for turbulence such as direct interaction approximation and EDQNM. For numerical techniques, I primarily use and modify the OpenFOAM code library, and have written in-house finite volume and DSMC codes, but also have some experience with Fluent, CFX, SU2 and the SPARTA DSMC code, and have worked with the FLASH multiphysics code. I am the main developer of a private fork of the OpenFOAM code, called ANUFoam. I am a peer reviewer for the AIP Journal Physics of Fluids, APS Physical Review Fluids and Springer Journal of Shock Waves. I am familiar with Python, MATLAB, C++, Fortran and Wolfram programming languages. I enjoy reading literary classics, philosophy, politics, history, among others, particularly Russian and English literature. My favourite authors are Chekhov and Turgenev. Avid chess student and player, currently rated 2200 on chesscom and 2400 lichess, hoping to obtain the CM title.

      Development of an in-house Direct Simulation Monte Carlo (DSMC) code for the simulation of rarefied flows in vacuum. The main interest concerns the thrust producing mechanism of nozzles operating in vacuum. This project is funded through multiple sources and is relevant to the development of Bogong 2.0, the second iteration of our naphthalene microthruster.
