BIO

As a Postdoctoral Researcher at the University of Vermont, I specialize in studying the fate and transport of phosphorus in soil and water systems. My research focuses on colloidal phosphorus, particularly its movement from soils to lake waters, including the characterization and quantification of mobile, immobile, bioavailable, and non-bioavailable colloidal phosphorus fractions. I also investigate the factors influencing their transport under changing climate conditions. In addition to my research, I serve as the Secretary of the Postdoctoral Association at the University of Vermont. I have authored over 20 SCI-indexed publications and serve as a peer reviewer for several international journals in the fields of environmental science and sustainability.
