Gary Lynn Comstock was appointed as Professor of Philosophy at North Carolina State University in 2002. He conducts research on a wide range of ethical questions and on methods of teaching critical thinking. He is especially interested in animal minds and the moral relevance of what's known and not known about the brains and behaviors of nonhuman animals. He has received awards for both his research and teaching.  His essay, "Imagining Other Species' Pains" was named Best Oral Presentation of the 2025 International  Conference on Animals; his essay, The Shrimp Hypothesis was selected as Best Paper of the 2022 Interspecies Comparisons of Welfare conference at the London School of Economics; and his New York Times article, "You Should Not Have Let Your Baby Die," received Honorable Mention in the PEA Soup 2017 Ethics Prize competition.  In 2015, he was chosen as an NC State Alumni Association Outstanding Teacher of the Year. In 2020 he was named Alumni Association Distinguished Undergraduate Professor, after having created How We Evaluate , an online course in critical thinking.

An active collaborator, Comstock has written with Peter Singer and Adam Lerner legal briefs and an op-ed, "Why the Court Should Free Happy" (2022). With eleven philosophers, he coauthored Chimpanzee Rights: The Philosophers' Brief (Routledge, 2019). He wrote Research Ethics: A Philosophical Guide to the Responsible Conduct of Research (Cambridge, 2013) and Vexing Nature? On the Ethical Case Against Agricultural Biotechnology (Kluwer, 2000).  He coedited The Moral Rights of Animals (Lexington, 2017).

For two years (2007-09), Comstock was ASC Fellow of the National Humanities Center.

There he produced two editions of a textbook, Religious Autobiographies (1994; 2nd ed., 2003), won his College's Award for Excellence in Outreach, and contributed to establishing the Bioethics Institute, a faculty development workshop that helped some five hundred scientists to integrate discussions of ethics into their courses.
