Vamsi Ganti's research seeks to quantify and understand the mechanics of physical processes that shape the landscapes on Earth and other planets, and to unravel the expression of these processes in the ancient sedimentary record. He works on a range of environments (from erosional to depositional landscapes), across a wide range of spatiotemporal scales (from migration of a single river dune to the scale of sedimentary basin filling), and across modern and ancient systems. The unifying themes that connect these contrasting scales and environments is our desire to quantify the effect of variability, and to quantitatively map the dynamics of surface processes to their depositional products in the ancient rock record.
