John Alroy

John Alroy is an Associate Professor in Macquarie University's Department of Biological Sciences and the overseer of the Fossilworks and Ecological Register websites. He holds an undergraduate degree from Reed College and a PhD from the University of Chicago.

Dr Alroy's research previously focused on diversity curves, speciation, and extinction in the deep fossil record, with most of his publications being on Cenozoic mammals and Phanerozoic marine invertebrates. He is currently focused on quantifying biodiversity and extinction in Recent organisms on global, regional, and local scales.

Methods and models developed by Dr Alroy include shareholder quorum subsampling, gap filler turnover rate equations, equations for putting Bayesian credible intervals on extinction dates, the rescaled Forbes index, and the double geometric distribution.
