Here’s a Wordle of abstracts from my peer-reviewed articles (see Publications page). “Sediment”, “Deposit”, and “Basin” came out on top with 64, 52, and 39 occurrences each!

Some of the first detrital zircon U-Pb ages produced from the Trace Element and Radiogenic Isotope Laboratory (TRAIL) at the University of Arkansas! These data are from a 13,000 year old sample from a submarine fan offshore southern California

I’m excited to announce a new project with Devon Energy on using 3D Digital Outcrop Modeling as an Analog for Subsurface Reservoir Characterization! I am looking for a motivated M.S. student to work on this project, starting Fall 2018. Please contact Dr. Glenn Sharman (gsharman@uark.edu) if interested.


Sam Johnstone and I recently coauthored a paper in Earth and Planetary Science Letters called Sediment Unmixing using Detrital Geochronology. This figure illustrates forward mixing models using a number of different goodness-of-fit metrics.
