G. Alex Janevski

Ph.D. Student in Geological Sciences
Predoctoral Fellowship

G. Alex Janevski’s research focuses on long-term trends in the fossil record of marine invertebrates. He wants to know to what extent what we see in the fossil record could be a product of random fluctuations not requiring special explanation. Do mass extinctions all have discrete causes, or does extinction ever occur randomly among species? How do we compare the extinctions of the past as recorded in the fossil record with the modern biodiversity crisis? He has also spent a great deal of time working on the fossil record of crinoids, one group of which survived the largest mass extinction in the history of life, approximately 250 million years ago.
