Barbara Block is the Prothro Professor in Marine Sciences at Stanford University and co-founder, with the Monterey Bay Aquarium, of the Tuna Research and Conservation Center. She researches how large pelagic fish (tunas, sharks, and billfish) utilize the ocean and has pioneered electronic tags to track where they go in the oceans. Block was previously a professor at University of Chicago. She has published 220 peer-reviewed papers and edited two volumes on tunas. Her honors include the NSF Young Investigator Award, a MacArthur Fellowship, a Pew Conservation Fellowship, and the Benchley Prize for Ocean Science.
