PROFESSIONAL INTERESTS:

Dr. Zhang's major interest is in numerical simulation of contaminant fate and transport in natural media. Especially interested in the development and application of non-local transport theories and models for anomalous dispersion, shallow groundwater age dating with environmental tracers, subsurface heterogeneity characterization (geostatistical and stochastic methods), saturated zone flow and transport parameter upscaling, saline water intrusion, heat transport, aquifer vulnerability assessment, and random walk approximations of partial differential equations.

RESEARCH AREAS:

Groundwater hydrogeology, contaminant transport, fractional calculus
