Tim Bralower was born in Armonk, NY but moved to London at the age of four. Tim attended Oxford University and received a BA in Earth Science. Tim followed his undergraduate degree with a PhD in Earth Science at Scripps Institution of Oceanography at the University of California San Diego. Although a classically trained marine geologist, Tim's specialty is calcareous nannoplankton, a group of marine plankton that leave an exquisite fossil record. The nannoplankton allow us to tell time or date ancient sediments back to 225 million years ago, and, in addition, inform us about environments in the past. Recently Tim has focused his research on ancient time periods when climate warmed rapidly. In particular, he is interested in what happens to life during these episodes.
