Faculty Overview
Dr. Flinchum’s teaching and research focuses on creatively combining near-surface geophysical measurements to improve our understanding of the physical and chemical processes that occur near Earth’s Surface (up to ~100 m depth). He is interested in using these measurements to improve our understanding of the relationships between geophysical, hydrological, and geochemical parameters, elucidate complex processes that shape and maintain the subsurface structure, and improve our understanding of the distribution of groundwater in the shallow subsurface. Dr. Flinchum’s research utilizes field-based measurement and reaches across scientific disciplines to decipher and integrate geophysical data sets with other data collected on different spatial and temporal scales.
