My research lies at the intersection of geochemistry, spectroscopy, and computational science. Specifically, I work in the following areas:
- X-ray Spectroscopy for Geochemical Element Behavior:I utilize advanced X-ray techniques, particularly Valence-to-Core X-ray Emission Spectroscopy (VtC-XES), to investigate the local chemical environments and bonding characteristics of Hf and Zr compounds (notably fluorides and oxides), as well as their complexes. This enables the study of intra- and intermolecular interactions, elemental migration pathways, and the geochemical fractionation mechanisms of twin element pairs such as Zr–Hf and Ho–Y.
- Infrared Spectroscopy of High Refractive Index Materials: I apply both 1D (e.g., ATR-FTIR) and 2D (2DIR) infrared spectroscopy to study the vibrational properties and spectral anomalies of ultrahigh refractive index materials—including ZrC, HfC, carbon, and graphite—especially when mixed or interacting with organic matter.
- Deep Learning for Spectral Identification and Correction:I leverage deep learning approaches, including LSTM and Transformer architectures, to process complex spectroscopic datasets.
