I’m Ashley Rivas, a 4th year PhD candidate in the Tarhan Lab at Yale University. I consider myself a geobiologist and paleontologist.

My geology career started during my undergraduate at Smith College with Sara Pruss as my thesis advisor. At Smith, I studied skeletal abundance during the early Ordovician in Laurentian rocks to understand how the Great Ordovician Biodiversification Event impacted diversity in the shallow realm.

Since then, I’ve published on enigmatic Ediacaran fossils as a side project advised by Lidya Tarhan and Derek Briggs at Yale University, and am currently working on my largest project yet on bioturbation development through the early Paleozoic for my dissertation.

Stay tuned for research updates, and in the meantime check out my CV!
