Kyle Johannsen is a Sessional Faculty Member in the Department of Philosophy at Trent University, and he's a podcast host on the New Books Network's Animal Studies Channel. He has a Ph.D. in Philosophy from Queen’s (2010 – 2015), and his research is in animal and environmental ethics, and in political philosophy. His animal-related work focuses specifically on wild animal suffering. Though many political philosophers and ethicists have the intuition that we should leave nature alone, Johannsen argues that we have a duty to research safe ways of providing large-scale assistance to wild animals. His monograph Wild Animal Ethics: The Moral and Political Problem of Wild Animal Suffering (Routledge, 2021), explores how a collective, institutional obligation to assist wild animals should be understood. His edited collection Positive Duties to Wild Animals (Routledge, 2024) further develops the interventionist literature on wild animal suffering using different theoretical frameworks, including some that have never previously been used to ground our duties to assist wild animals. Johannsen's collection was originally published as a special issue of Ethics, Policy & Environment.

Julia Gibson was the 2019-20 Postdoctoral Fellow in Animal Studies at Queen’s. She was appointed to the Environmental Studies Department of Antioch University New England in 2021. She envisions her research taking shape where the boundaries between feminist, political, and environmental philosophy grow pleasantly and productively murky. During her postdoctoral fellowship, she dig deeper into her research on transformative interspecies justice. Julia did her doctoral work in Philosophy at Michigan State University, writing her dissertation on palliative and remembrance ethics for the dead and the dying of climate change. Before obtaining her MA in Philosophy from the University of Colorado in 2013, she spent two years working at an international salmon conservation organization in Portland. She received her BA in Philosophy and Russian Studies from William Smith College in 2009. Julia has authored publications in bioethics, technology studies, mobilities studies, and animal ethics.

Josh Milburn was the 2016-2017 Postdoctoral Fellow in Animal Studies in the Queen’s University Department of Philosophy. While at Queen's, he explored the ethics of feeding animals. The results of this research were published as his 2022 McGill-Queen's University Press book Just Fodder: The Ethics of Feeding Animals. After his time at Queen's, Josh returned to the UK, working at the University of York and the University of Sheffield. He started a lectureship in the Department of International Relations, Politics, and History at Loughborough University in 2022. His second book, Food, Justice, and Animals: Feeding the World Respectfully, was published in 2023 by Oxford University Press; his third, Animals, State, and Utopia: Robert Nozick's Animal Ethics is forthcoming, also with Oxford University Press. Josh has been the host of the animal studies podcast Knowing Animals, which has featured many members of APPLE as guests, since 2020.

Jeremy Fischer is a writer interested in the psychological underpinnings of inegalitarian and undemocratic social relations. His works include “Racism as Civic Vice” (published in Ethics) and “Feeling Racial Pride in the Mode of Frederick Douglass” (published in Critical Philosophy of Race). His current research on human relations with animals considers the ethics of training children to consume animal products. His paper, “Creating Carnists” (co-authored with Rachel Fredericks and published in Philosophers’ Imprint) sketches some concerns about such caregiving. He also has research interests in ethical and political topics relating to the COVID-19 pandemic, and in the work of Peter Kropotkin. He lives in Chicago.

Hilal Sezgin is an independent researcher, publicist and writer of both fiction and non-fiction. Her main topics are animal rights and animal ethics, which are inspired by her Frankfurt School background as well as by feminist ethics. Based in rural Northern Germany, she runs a small private sanctuary for mostly elderly sheeps. This led her to thinking and writing about moral conflicts which arise out of actual situations of care (euthanasia, parentalism, autonomy of the cared-for, internalized speciesism) and about difficult moral decisions in dealing with „wild“ animals. Her most recent book tells of sanctuary life with a main focus on ageing and disabilities. Currently, she tries to figure out how one can support environmentalism and theorize rights of nature without losing sight of the individual rights of more-than-human animals. Her podcast “Lektüren mit Tieren” (“Readings with Animals”) discusses non-fiction books which either speak about, or neglect in a significant way, more-than-human animals.

Hannah Hunter is a Vanier Scholar and obtained her PhD in the Department of Geography and Planning at Queen’s University. Her doctoral research explores the collection and afterlives of animal sound recordings, particularly in the context of extinction. She works at the intersections of sonic geography, environmental humanities, and social studies of science, and is broadly interested in the interactions between humans, animals, and technologies.

Darren Chang is PhD candidate in Sociology and Criminology at the University of Sydney. His research interests broadly include interspecies relations under colonialism and global capitalism, practices of solidarity, kinship, and mutual aid across species in challenging oppressive powers, social movement theories, and multispecies justice. Through political (and politicised) ethnography at animal sanctuaries, Darren’s PhD research project explores potential alignments and tensions between animal and other social and environmental justice movements. The multispecies dimension of this project also considers the place, positions, and subjectivities of nonhuman animals in relation to anthropogenic social movements.

Claudia Hirtenfelder is an independent researcher and podcast host. She completed her PhD at Queen's University focusing on the history and geography of how cows and how they were problematized in Kingston, Ontario.

Claudia is also the host of the Animals in Philosophy, Politics, Law, and Ethics (APPLE) sponsored podcast The Animal Turn in which she talks to scholars about important concepts in animal studies.
