NRE 406/506- Soil Microbiology/Biochemistry
My interest focuses on the role of phytases, phosphatases, and amidohydrolases on the biogeochemical cycling nutrients in the environment, using and developing various analytical procedures and advanced instruments to understand mercury, arsenic and pesticides speciation in organic and inorganic production systems, use of 31-P NMR, FTIR, XANES, and EXAFS in the study of organic and inorganic phosphorus, carbon, and nitrogen in the environment, spatial distribution of nutrients, and composition, stability and interaction of humic substances in the environment, use of molecular techniques to characterize the microbial community structure and diversity of soil.
Studies on trace and heavy metal chemistry, chemical fractionation, and biologically reduced metals.
Microbial diversity in agronomic systems
Impact of cropping systems and landscape positions on microbial respiration, CO2 fluxes and moisture variability.
Phosphatases and amidohydrolases hydrolysis of organic compounds and 31P NMR quantification of soil organic phosphorus.
Using FTIR and 13C NMR to determine composition, stability, and reactivity of humic substances.
Investigating spatial variability of phosphorus fractions in organic and inorganic production systems.
Investigating mercury and arsenic cycling in environmental samples.
