About Me


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

Philosophy & Approach

Iā€™m a geosciences researcher in an era of ever-growing datasets.

I apply innovation in computation, geostatistics, and machine learning to problems in sedimentology, coastal and hydraulic engineering, geophysics, hydrology and geomorphology, by developing and applying novel data analytics to novel datasets.

I have developed algorithms and written multiple articles on stochastic statistics, machine learning and artificial intelligence for quantifying land cover, sediment properties, and oceanographic processes in images and acoustic data.

I am a strong supporter of open source software and I develop and contribute to community tools for scientific discovery.

Research Interests

Sediment: what is it made of, what lives in or on it, how it gets picked up by flows of air and water, how it forms and solves engineering problems, and how it modifies landforms in deserts, rivers and seas.


I have a Ph.D in Coastal Geomorphology/Nearshore Oceanography from the University of Plymouth, UK (2008). My doctoral research was on gravel beach

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.

I am Assistant Research Professor within the School of Earth & Sustainability, and Affiliate of the School of Informatics, Computing, and Cybersystems, at Northern Arizona University.
