Research Interests
My Ph.D. research focuses on soil organic matter stabilization via interactions with soil minerals, including understanding the effect of variable environmental properties on stabilization processes. At Hubbard Brook, I am applying the hydropedologic unit (HPU) framework to evaluate metal-organic interactions in soils with varying saturation frequency, using spectroscopic characterization and high-resolution imaging techniques.
