Climatic controls on erosion and landscape evolution
Because climate change is predicted to alter the frequency and magnitude of storms in the coming decades, quantifying the erosional responses to rainfall and waves are urgent problems in Earth science. Despite longstanding expectations for relationships between climate and erosion rates, measuring such a signal in field data has proven surprisingly difficult – partly because many non-climatic factors (e.g. lithology, rock uplift rates) also influence erosion rates and partly because erosional processes may respond to temporally variable climatic conditions in nuanced ways. Isolating the influence of climate on erosion rates and understanding the impact of hourly to million-year scale climate variability on earth surface processes are open challenges, so basic questions about how climate change will affect Earth’s surface remain unanswered. This knowledge gap also hinders efforts to infer tectonic history from topography, interpret sedimentary records, and understand feedbacks between erosion, weathering, CO2 drawdown, and climate change over geologic timescales. Some of the clearest relationships between climate and erosion have been measured in landscapes with relatively uniform lithology and tectonic uplift rates or in landscapes where these competing factors are well characterized. My research uses these natural laboratories to examine the influence of climate mean and variability on fluvial and coastal erosion rates and landscape evolution over glacial-interglacial to million-year timescales.

Topographic constraints on lithosphere and mantle dynamics
Topography can provide important observational constraints on the rheology, thermal evolution, and dynamics of the lithosphere and mantle – all of which have implications for understanding Earth's heat budget, the styles of deformation that develop at plate boundaries, and the surface expressions of mantle convection. Tectonic and geodynamic processes drive rock uplift and alter the base level of rivers and hillslopes by changing relative sea level. They consequently exert dominant control on terrestrial and submarine geomorphology; virtually all of Earth’s steepest landscapes are found in regions of rapid rock uplift, and conductive cooling of the lithosphere is the first-order control on global seafloor depths. Topo-bathymetry, paleoshorelines, and sedimentary records can therefore provide an invaluable window to deep earth processes operating today and in the geologic past. My research uses geomorphic observations - including the morphology of bedrock coasts, river profiles, and drainage networks - to constrain plume-plate interactions at ocean hotspots, relative sea level histories, and paleotectonics.

Oscillatory flow sand ripples
Because the spacing of orbital sand ripples formed by shallow water waves scales with wave conditions and water depth, ripples preserved in sedimentary rocks can be used to infer paleoenvironmental conditions. However, modern and ancient ripple fields often contain defects - deviations from straight, evenly spaced crests - whose formation and evolution are not well understood. At MIT, I performed a series of experiments in a field-scale laboratory wave tank to characterize the response of a rippled bed to changing wave conditions.
