Biography

Lirong Zhong has over 16 years of experience in environmental science and engineering research. Since joining PNNL in 2003, his work has focused primarily on groundwater and vadose zone contamination remediation technology development and subsurface characterization. His research interests cover a broad range of areas that pertain to subsurface science and characterization, contaminate fate and transport, and aquifer and vadose zone remediation engineering. He has conducted researches on enhanced delivery of remedial amendments to aquifer and vadose zone, contaminant mobilization by supercritical carbon dioxide and the fate of mobilized compounds, gaseous treatment for vadose zone remediation, and enhanced vadose zone non-aqueous phase liquid (NAPL) removal and vadose zone metal/radionulides immobilization. He is also interested in rheological characterization on fluids and gels, in fluid flow behavior under high pressure and temperature conditions, and in GC-MS/MS analytical method development.
