プロフィール概要

I am a theoretical and computational physicist specializing in electronic structure, computational materials science, quantum materials, and scientific computing. I have more than 15 years of research experience across Europe, the United States, and South Korea, including research positions at leading institutions in condensed matter physics. My work combines analytical modeling, large-scale numerical simulations, and scientific software development to understand the electronic and transport properties of complex materials. I have extensive experience developing and applying tight-binding and continuum models, density functional theory (DFT), electronic-structure methods, quantum transport calculations, and high-performance computing (HPC). My current and recent research focuses on 2D and quantum materials, including graphene, multilayer graphene, van der Waals heterostructures, moiré systems, topological electronic states, correlated-electron phenomena, and transport. I also work on computational modeling of more conventional materials using first-principles methods, including DFT+U calculations of complex oxides. I have substantial hands-on experience with Python, Fortran, Linux, SLURM/HPC environments, numerical data analysis, scientific visualization, and the development and optimization of research codes. I routinely work with large numerical datasets and computational workflows ranging from model development and implementation to simulation, analysis, interpretation, and publication-quality visualization. I can assist clients with projects including: Computational materials modeling and electronic-structure calculations DFT and DFT+U calculations and interpretation Tight-binding, continuum, and effective-model development Quantum and electronic transport modeling 2D materials, graphene, moiré systems, and quantum materials Numerical method development and validation Scientific Python and Fortran programming HPC workflows, parallel calculations, and computational optimization Analysis and visualization of complex scientific datasets Reproduction or independent verification of published computational results Literature reviews and assessment of scientific or technological claims Technical and scientific due diligence Scientific manuscripts, reports, and research proposals I have authored and co-authored numerous peer-reviewed publications in condensed matter physics and computational materials science and have extensive experience collaborating with both theoretical and experimental researchers. This allows me not only to perform calculations, but also to identify the appropriate physical model, assess whether results are physically meaningful, and communicate conclusions clearly to both specialist and non-specialist audiences. I am particularly interested in well-defined consulting projects where advanced scientific judgment and computational expertise are required, whether the goal is to solve a specific modeling problem, validate existing results, evaluate a technology, develop or improve scientific software, or determine the most effective computational approach to a research question.
