Shern specialises in theoretical and computational molecular dynamics for modelling of non-equilibrium systems and electrode-electrolyte interfaces.

Dr Shern Tee's research covers various methods for modelling complex, technologically-relevant systems at the molecular level using advanced molecular dynamics techniques, using the constant potential method and non-equilibrium dynamics. In the constant potential method, electrode atoms are given dynamically-varying charges, allowing electrodes to be charged or discharged in a computer simulation. This extends molecular dynamics to modelling complex electrophysical systems such as supercapacitors, capacitive desalinators and electrodes with nanoscale complexity. In non-equilibrium dynamics, we allow the fluids in our simulations to continuously flow, slide and shift, with potential applications ranging from nanofluidics to 3D-printing. Accurate non-equilibrium dynamics require careful accounting of the energy constantly entering and exiting a system so that simulations correspond accurately to real-world situations instead of computerized artifacts. Across all these applications, completing useful simulations demands accurate and efficient computer code, and Shern's research also covers developing and maintaining code for the open source software LAMMPS to enhance its capabilities.

​Dr Shern Tee completed his Bachelor in Philosophy (Physics) at the Australian National University, writing his Honors thesis on modeling optical-trapping containers using the fluctuation theorems. After a stint teaching physics in Malaysia, he went on to complete his PhD at the National University of Singapore on coarse-grained modeling of biomimetic track-walking molecular motors built from DNA. He then moved to Australia and began his current postdoctoral position at the AIBN in 2018. Alongside his academic research, Shern is passionate about openness and collaboration in computational science, contributing to the annual Research Bazaar (ResBaz) Queensland as a Python instructor as well as the Turing Way and Research Software Engineering Australia-New Zealand online communities.
