International Audience Summary Of Expertise
-
Dr. Nick Pyenson is a paleontologist who studies how marine animals, such as whales, sea cows, and sea turtles have evolved over millions of years. He uses information from the fossil record and the anatomy of these animals to understand how the evolved and their ecology in the world today. Many marine animals are important to human cultures, and some are highly threatened by human activities. Understanding the evolution and ecology of these species will contribute to better knowing how they will respond to global climate change.
Dr. Pyenson’s scientific expeditions have taken him to every continent. For him, international collaborations are essential for accomplishing the basic research, but also for: building scientific research capacity; mentoring the next generation of scientists; and communicating what we know about the deep history of life on Earth.
The results of his team’s discoveries have been published extensively, including cover articles in the prestigious journals Science and Nature. Along with his collaborators, he has named over nearly a dozen new species of fossil vertebrates, discovered the richest fossil whale graveyard on the planet in the Atacama of Chile, and described an entirely new sensory organ in living whales.
His research has received the highest awards from the Smithsonian, and he has also received a Presidential Early Career Award for Scientists and Engineers from President Obama’s White House. Dr. Pyenson’s popular book describing his research, Spying on Whales, was featured on US television and radio, and included in many best science book compilations. It will soon be available in Russian and Chinese language editions.
He completed his postdoctoral fellowship at the University of British Columbia, he received his doctoral degree from the University of California, Berkeley, and he has a bachelor’s degree from Emory University. Pyenson is also a member of the Young Scientists community at the World Economic Forum.
