My name is Yoichi Ishida (pronounced “yo-EE-chee ee-SHEE-da”). Until August 2022, I was an Associate Professor in the Department of Philosophy at Ohio University. I work in history and philosophy of science, with a focus on biology. My philosophical and scientific articles have been published in Philosophy of Science, Studies in History and Philosophy of Biological and Biomedical Sciences, Synthese, BioEssays, Bone, and Journal of General Physiology. I hold a PhD in History and Philosophy of Science from the University of Pittsburgh, where my advisors were Sandra Mitchell and James Lennox. Before that, I studied philosophy at the University of Nevada, Reno, where my advisor was Thomas Nickles.

I recently contributed an autobiographical essay to The American Philosophical Association Newsletter on Asian and Asian American Philosophers and Philosophies: What Is It Like to Be a Philosopher of Asian Descent? (Volume 20, no. 1, Fall 2020). My essay is on pp. 28–30.

I use historical and philosophical methods to understand scientific practice. I am especially interested in representations of biological phenomena, such as mathematical models and diagrams.
