Ethics of AI, Animals, and Nonhumans

I examine moments where AI reshapes human judgment and social values alongside moments where human societies decide the lives and deaths of animals as connected problems in ethics.

Work & contact

AI and Moral Judgment

I study how AI changes human judgment and social values. Moral reasoning by LLMs can improve our judgment, or manipulate it.

Politics Including Animals

I treat animals as political beings. Human societies determine animal life and death, yet animals cannot join public deliberation.

Utilitarianism and Minority Experience

I use utilitarianism to examine animals, poverty, future generations, and AI. As a vegan, queer, nonbinary person, I also write about experiences outside social norms.
