Welcome to my website
This is Chia-Yu Yang
Postdoctoral Researcher at Kyoto Prefectural University
I am a researcher in soil science focusing on Cr- and Ni-rich ultramafic and serpentine soils. I employ soil morphology, mineralogy, geochemistry, and magnetics to investigate the influence of parent material, topography, and climate on soil formation and the bioavailability of potentially toxic elements. I also explore enhanced rock weathering (ERW) as a pathway for carbon removal and sustainable agriculture. My goal is to build a unified framework linking soil evolution, mineral transformation, environmental risk, and sustainable ecology.
