He received his PhD in Philosophy from the City University of New York Graduate Center in 2013. Since then he has come to specialize in the emerging field of Philosophy of Paleontology, working on conceptual issues in extinction and the metaphysical background of dinosaur research. He is working with Edward Davis on his M.S. in Paleontology. In addition to this research, Leonard has written a number of outreach essays on a variety of topics including ethics, possible-world semantics, and human nature. He will also occasionally indulge interests in astronomy, prehistoric art, science fiction, and graphic novels. Leonard’s favorite dinosaur is Tyrannosaurus rex. He acknowledges that this is an uninteresting choice. Please pretend that he said Yutyrannus huali instead.
