Robert J M Hudson serves as Associate Professor in the Department of Natural Resources and Environmental Sciences at the University of Illinois Urbana-Champaign, focusing on environmental chemistry and engineering with emphasis on water quality, biogeochemical processes, and sustainable treatment systems. His work bridges fundamental chemical analysis with practical environmental applications across watershed management and engineered remediation.

Research interests center on trace metal dynamics (particularly mercury and MeHg cycling), bioreactor technologies for agricultural drainage, and algal-bacterial biofilm systems for wastewater treatment. Key investigations include coordination chemistry of thiourea complexes, marine phytoplankton interactions with trace metals, and grant-free analytical methodologies for environmental monitoring. His fingerprint metrics highlight dominant expertise in mercury speciation (100%), MeHg pathways (81%), and trace metal coordination (73%).

Recent publications demonstrate a clear trajectory from fundamental metal complexation studies (2015) toward applied bioremediation systems, with increasing focus on high-strength wastewater treatment and watershed-scale release analysis. The work consistently integrates chemical speciation with biological processes, particularly through rotating algal-bacterial contactor systems showing 100% efficiency in ammonia removal and biofilm optimization.

Collaborative projects include the Watershed-Specific Release Rate Analysis for Cook County (2022), involving multidisciplinary teams from Prairie Research Institute addressing drainage event modeling. Current efforts focus on scaling bioreactor technologies for municipal wastewater sidestreams and agricultural runoff mitigation through denitrification pathways.
