My research interests bridge physics and physical chemistry within the realm of materials modelling. I have a particular interest in materials with application to renewable energy, battery or sensing technologies. Although I typically focus on nanoscale materials (e.g., small metallic clusters, quantum dots, carbon nanotubes), I also have a strong interest in surfaces and 2D materials.
My modelling expertise spans a variety of code bases and many levels of theory: first-principles (DFT), the highest-level ab initio methods (wavefunction-based post-Hartree Fock), and classical (force field) simulations. I have extensive C/C++ and python experience, and an easy familiarity with Fortan 90, IDL, and Matlab.
My current research focus includes:
- computational material science
- 2D materials
- nanoscale materials for energy and catalytic applications
- thermodynamic properties of materials
