Department of Plant, Soil and Microbial Sciences Kravchenko Lab

Research Profile & Interests:

I am a Keegstra Postdoctoral Researcher in Dr. Alexandra Kravchenko's lab at Michigan State University. My research program is centered on soil carbon biogeochemistry — exploring the impact of novel bioenergy sorghum hybrids on root–soil interactions, soil microbiome dynamics, and soil carbon sequestration. I employ ¹³C isotope labeling to trace plant-derived carbon delivered to the soil and its subsequent fate and protection within the soil matrix, alongside soil enzyme activities as proxies of microbial-driven carbon transformations, microbiome composition characterization, and molecular approaches to unravel the microbial mechanisms governing carbon cycling in soil systems.
