Leonard Finkelman is an assistant professor of Philosophy at Linfield College. He received his PhD in Philosophy from the City University of New York Graduate Center in 2013 and a Master of Science degree in Earth Sciences from the University of Oregon in 2019. He works on conceptual issues in extinction and the metaphysical background of dinosaur research.

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.

Leonard's work has been profiled in Wired Science and The Oregonian.
