About Me


Assistant Research Professor, School of Earth Sciences & Environmental Sustainability, Northern Arizona University


I am a data-driven geomorphologist and sedimentologist. I apply machine learning, frequency domain techniques and probabilistic analyses to understand inter-relations between fluid flows, evolving landforms, sediment transport and sedimentology.

My Background

I have a Ph.D in Coastal Geomorphology/Nearshore Oceanography from the University of Plymouth, UK (2008). My doctoral research was on gravel beach
morphodynamics. My first postdoc (2008-2009) was at the University of California Santa Cruz, School of Earth & Planetary Sciences, in conjunction with the U.S. Geological Survey, studying inner shelf sediment transport processes. My second postdoc (2009 - 2012) was at the University of Plymouth, UK, School of Marine Science & Engineering, studying surf zone hydrodynamics and sediment transport processes. I worked as a Research Geologist (Nov 2012 - Nov 2016) at the U.S. Geological Survey, at the Grand Canyon Monitoring & Research Center in Flagstaff, Arizona, studying fluvial sediment transport and geomorphic processes in regulated rivers. As of November 2016, I am Associate Research Professor within the School of Earth Science & Environmental Sustainability at Northern Arizona University.

My Research

My research approach is interdisciplinary in sedimentology, coastal and hydraulic engineering, and geophysics, applying methodologies ranging from field surveys and laboratory analysis to analytical and numerical modeling. Of special interest to me is geostatistical analyses, computational geomorphology and sedimentology, stochastic modeling techniques, instrument design, and the remote characterization of sedimentary environments, which includes sensing the properties of flows and particles at rest and in motion, in single and multiphase flows, both terrestrial and subaqueous, by developing and applying novel acoustics and optics instrumentation and computational algorithms Additionally, I invest time in supporting, developing, and maintaining various open source scientific packages in the Python world. Through all of this, I enjoy working on the instrumentational and computational methodologies that are helping push forward geosciences research in the era of ever-growing datasets.
