About Me
I am currently the Clinical Ethics Fellow at the Girand Center for Biomedical Ethics at Stanford. Before that, I was a Bioethics Postdoctoral Fellow at the NIH, and I received my PhD in philosophy at the University of Wisconsin-Madison.
My research is about the human subject and its place in an increasingly complex world. On the "theoretical" side, this amounts to research on consciousness, perception, and other topics in the philosophy of mind. On the "practical" side, it amounts to research on euthanasia, AI therapy, and other topics in bioethics. I also have side interests in metaphysics.
I enjoy teaching and ethics consultation. I have almost ten years of teaching and grading experience, across a variety of formats, class sizes, and locations. My consultation experience so far includes research ethics (NIH) and clinical ethics (Stanford and MedStar Hospital). I believe that logic and ethics education are crucial in the classroom, the hospital, and beyond.
