Jacques Pienaar, previously Research Assistant Professor in the QBism group at the University of Massachusetts Boston, is now Collaborating Professor at the Federal University of Rio de Janeiro. He graduated with Honours from the University of Melbourne (2008) and obtained his PhD from the University of Queensland under the supervision of Timothy C. Ralph, where he specialized in quantum optics, quantum information and the foundations of quantum mechanics, with emphasis on quantum causality. He continued to explore quantum causality and foundations as a postdoc in the group of Časlav Brukner at the University of Vienna (2013-2016), and subsequently at the International Institute of Physics in the group of Rafael Chaves (2017-2018). Since 2019 he has been part of the QBism research group of Christopher Fuchs at UMass Boston and also collaborated closely with the Institute of Physics at UFRJ, working on the foundations of quantum mechanics with an emphasis on the themes of causality, measurement and the role of agency in physics.

Her research is dedicated to studying quantum phenomena, such as entanglement and imaging in quantum optics, and its application to the development of quantum information technology. Her research highlights include a quantum imaging technique, in which an image is made using entangled photons that did not interact with the object. She is currently involved in the Quantum Vision project, which converges neuroscience and physics to study whether and how our visual system perceives quantum phenomena. She is a member of the Justice, Equity, Diversity, and Inclusion Commission of the Brazilian Society of Physics (SBF) and recipient of the Mietta Santiago Medal (2019) which recognizes women at the forefront of their fields who have promoted the cause of women’s rights.

Michel Bitbol is emeritus Director of Research at the CNRS, in Paris, France. He is presently based at the Archives Husserl, École Normale Superieure. His distinguished career has traversed multiple disciplines: after completing a PhD in physics, he worked as a research scientist in biophysics before dedicating himself to the philosophy of physics, focusing on the foundations of quantum mechanics. His unique interdisciplinary approach has allowed him to explore the intersections between quantum physics, phenomenology, and cognitive science, drawing upon the ideas of notable philosophers such as Husserl, Heidegger, and Merleau-Ponty, as well as on ideas from Eastern philosophies, particularly Buddhism. He has made important contributions to the philosophy of mind, collaborating with Francisco Varela and has edited a collection of works by Varela. His accomplished bibliography includes 9 books, one of which notably draws on his knowledge of the ancient language of Sanskrit (“De l’intérieur du monde,” 2010) to draw parallels between the Buddhist concepts of dependent arising and non-supervenient relations and ideas in quantum physics.

Adam Frank is an astrophysicist and leading expert on the final stages of evolution for stars like the sun, and his computational research group at the University of Rochester has developed advanced supercomputer tools for studying how stars form and how they die.

A world-renowned theoretical physicist interested in cosmology, statistical physics, and astrobiology, he has published hundreds of peer-reviewed articles, and more than a thousand essays and op-eds, and frequently participates in TV documentaries and radio shows in the U.S. and abroad. He writes weekly for BigThink’s 13.8.

Richard Healey is Professor of Philosophy Emeritus at the University of Arizona, having worked there from 1991 to 2021. He continues to pursue his research and occasional teaching from his current home in Spain. Most of Healey’s current research is in the philosophy of science (and specifically the philosophy of physics) from a contemporary pragmatist perspective. His book The Quantum Revolution in Philosophy, a self-contained but opinionated introduction to quantum theory and its significance for philosophy, was published in 2017 (paperback 2019). He wrote the book to engage the interest of the educated reader as well as philosophers and scientists beyond specialists in conceptual foundations of physics. It illustrates the philosophical worth of pragmatist ideas by showing how they help us understand perhaps our most successful but most puzzling scientific theory. Since writing that book, Healey has continued to publish specialist papers in the philosophy of physics, and others exploring the relations between science and metaphysics from a broadly pragmatist perspective. An aim of his earlier research in the philosophy of physics was to shed light on metaphysical topics such as holism, realism and causation. In The Philosophy of Quantum Mechanics, Healey developed an approach toward the understanding of quantum theory according to which the theory portrays a nonseparable world, but his view of quantum theory has changed since writing the book. His recent book, Gauging What’s Real, locates a different kind of nonseparability in contemporary gauge theories. 

Lucy Mason is currently a postdoctoral researcher at Royal Holloway University, and prior to that completed a PhD in philosophy at King's College London and an MSci in physics and philosophy at the University of Bristol.
