Ab-initio Computational Materials Scientist | Hot Carrier Dynamics & Optoelectronics

Profile Summary

Ph.D. Candidate specializing in Computational Materials Science, focusing on first-principles simulations to investigate hot carrier dynamics mediated by electron-phonon interactions in materials like transition metal nitrides (TMNs). Highly experienced in bridging computational modeling with complementary experimental validation through transient absorption spectroscopy and perovskite device fabrication. Technical & Methodological Skills: * Proficient in ab-initio simulation packages: VASP, Quantum ESPRESSO, JDFTX. * Expert in advanced methods: DFT, GW, ab-initio e-ph coupling, and Boltzmann transport. * Skilled in applying Wannierization and EPW for charge carrier lifetimes and transport coefficient analysis. * Experienced in HPC environments, including PBS/Slurm scripting and parallel computing. * Strong programming background in Python (NumPy, Pandas, Matplotlib) for data visualization and analysis. Research Focus: * Electron-Phonon Coupling: Conducting DFT-based simulations on electron-phonon coupling and hot carrier relaxation in TiN and NbN. * Optoelectronic Materials: Prior work includes optimizing organo-halide perovskite thin films for solar cell applications and investigating the photocatalytic behavior of Janus TMDs via strain engineering.
