Being a chemist by training, my field of occupation is Physical Chemistry, in particular Theory and Molecular Simulation.
My research interests are Ionic Liquids and their mixtures, biophysical systems, processes under extreme conditions, and
the physics of liquid water, ice, clathrate-hydrates and aqueous solutions. I have been drawn to
problems where the ultimate goal is an understanding of the molecular underpinnings that can be communicated
to others in prose or pictures, rather than in tables or numbers. That said, being able to compute accurate numbers can sometimes be
also quite cool.

OrthoBoXY: A Simpler Way to Compute True Self Diffusion Coefficients and Viscosities from MD Simulations
- The "OrthoBoXY" methodology was first described in J. Phys. Chem. B 127, 7983-7987 (2023), and is available via DOI: 10.1021/acs.jpcb.3c04492. Our preprint can be downloaded from arXiv:2307.01591[cond-mat.soft].
- A recent extension of the "OrthoBoXY" approach to arbitraryly shaped orthorhombic boxes has just appeared in PCCP DOI: 10.1039/D3CP04916G and is available as preprint via arXiv:2310.01026[cond-mat.soft].
- An extensive demonstration on how to apply the method to compute self-diffusion coefficients and viscosities for a wide variety of substances has been recently published in J. Phys. Chem. B, and is available via DOI: 10.1021/acs.jpcb.3c07540. Our preprint is also available from ChemRxiv: DOI: 10.26434/chemrxiv-2023-fvf5q.
- A repository containing input files for performing MD simulations and the Fortran source code and examples for the numerical calculation of the Madelung constant analogues is available via GitHub.
BondAid: Correcting Hydrogen Bond Population Correlation Functions Obtained from Simulations with Periodic Boundary Conditions
- The methodology is described in our paper published in [J. Chem. Phys. 154, 214501 (2021)], which is available via DOI: 10.1063/5.0053445. The preprint is available as PDF. Note, that this article may be downloaded for personal use only. Any other use requires prior permission of the author and AIP Publishing.
- The source code for performing the corrections, and examples based on MD simulations of 1024 TIP4P/2005 water molecules as described in our paper are available via GitHub.
