Ph.D. Philosophy, UCLA 2006

Dr. Castro's research is centered in Kant scholarship, informed by current science with a broadly interdisciplinary aim. She is currently working on a book about Kant's metaethics, specifically how to establish a metaphysics of morals as a non-empirical science. More broadly, Dr. Castro is interested in the family of phenomena involved in acting or cognizing as if, in a wide range of contexts that include an imagination-centered Kantian theory of autism, algorithmic agency and social justice, Immanuel Kant’s peculiar moral imperative to "act as if your maxim were to become by your will a universal law of nature" (aka Kant's formula of nature), and Japanese philosophy of art (mastery and performance in renga and Noh).   

Professor Castro teaches Late Modern Philosophy, Metaethics, Ethical Theory, Philosophy of Law, Philosophy of Medicine, Philosophy of Feminism, Philosophy of the Arts, and Business Ethics.  In Fall 2021 she will be teaching a new first year seminar On Humor (see syllabus).

Brian HepburnBRIAN HEPBURN, Associate Professor and Undergraduate Coordinator

Office: 206 Fiske Hall

Phone: (316) 978-7887

BASc, Physics and Philosophy, 1999, University of Lethbridge. PhD, History and Philosophy of Science, 2007, University of Pittsburgh. Postdoctoral Fellow: University of British Columbia 2007-2011; Aarhus University (Denmark) 2011-2014.

Professor Hepburn's current research interests are scientific explanation, problem solving and innovation, particularly all three in interdisciplinary contexts. His dissertation was on how the concept of equilibrium was used in explanations in 18th century physics, and how this usage was connected to mathematical changes. He continues to work on an historical and philosophical picture of how the descriptive and explanatory resources we have available contribute to the problems we can solve. Especially interesting is when resources from different domains (whether scientific or not) can be integrated in some way. He hopes to use these insights to inform education in Science Literacy and Science Proficiency.

"My area of specialization is philosophy of science, broadly construed. Much of my work concerns models and analogical reasoning in some way, whether in engineering, physics, geophysics, biology (Darwin), or artificial intelligence. One of my contributions has been to argue for the significance of the concepts of physical similarity and physically similar systems, already recognized as important in science and engineering, to philosophy of science. I use both historical and analytical approaches -- often together.

Besides the major works on analogical reasoning, models and modeling: I've published a group of papers on Alan Turing and natural and artificial intelligence. In an advanced undergraduate interdisciplinary textbook on logic, I presented and discussed alternatives to classical logic that are valuable in automated reasoning systems faced with inconsistent information. Overall, I have published widely on the history and philosophy of science, of technology, and of engineering methodologies."
