John Alroy

John Alroy (born July 3, 1966 in New York City ) is an American paleontologist and evolutionary biologist.

Alroy studied biology at Reed College with a bachelor's degree in 1989 and received his doctorate in 1994 from the University of Chicago (Committee on Evolutionary Biology). He was a post-doctoral student at the University of Arizona , the Smithsonian Institution (1996-1998) and the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara (UCSB). From 2000 he researched as an assistant at the Institute for Marine Research at UCSB and from 2010 at Macquarie University in Sydney as a Future Fellow and Associate Professor.

He examines the development of biodiversity, mass extinction (also through human intervention) and evolutionary patterns of marine invertebrates in the Phanerozoic , among other things , but also the extinction of mammal species in North America (through human influence). In 2017, he estimated the decline in biodiversity due to man-made mass extinction in the tropical rainforests at around 40 percent.

In 2007 he received the Charles Schuchert Award , in 1994 the Romer Prize of the Society of Vertebrate Paleontology and in 2010 the NAS Award for Scientific Reviewing .
