Alexander Clarke is a PhD student in the Department of Earth and Planetary Sciences. Though he grew up in Phoenix, Arizona, he had the opportunity to acclimatize to the New England winters while studying biology and economics at Dartmouth College. At Yale, his PhD research focuses on the processes that have shaped Earth’s remarkable biodiversity over the last 500 million years. When he’s not digging up fossils or sequestered in depths of the Peabody Museum, Alexander enjoys trivia, Dungeons and Dragons, hiking, reading (especially Agatha Christie’s mystery novels and J.R.R. Tolkien’s Legendarium), and playing cribbage. He is excited to get to know the Berkeley College community!
