Ethics of AI, animals, and nonhuman beings.

My work spans AI research and the ethics of AI and animals. In AI research, I work on discriminatory bias and the morality of AI. In ethics, I focus on the moral treatment of nonhumans (AI and nonhuman animals). As a vegan, queer, and nonbinary person, I am also interested in how ethics addresses experiences that fall outside social norms.

Research Themes

AI and Moral Judgment

I study how AI systems change human judgment, philosophy, and social values. When LLMs give reasons about moral and political issues, they can improve judgment or steer it through manipulation and excessive guidance.

  • Whether AI can improve human morality
  • Which parts of philosophical research can be automated, and where human judgment remains necessary
  • How bias research in AI can be extended to speciesism toward nonhuman animals

Politics Including Animals

In animal ethics, I treat animals as political beings. Human societies determine much of animal life and death, while animals themselves cannot participate in public deliberation.

  • Ethical issues concerning meat eating, animal agriculture, animal experimentation, and wild animals
  • Politics and democracy including animals
  • Intersections among AI ethics, robot ethics, and animal ethics

Public Engagement

AI ethics and animal ethics shape decisions made by citizens, educators, policymakers, and practitioners. I also work through public writing, media engagement, workshops, and academic community building.
