Nate Soares heads MIRI’s research program. He first joined MIRI in 2014 as a research fellow, quickly earning a strong reputation for his strategic insight and high productivity. Nate is the primary author of most of MIRI’s agent foundations technical agenda, including the overview document “Agent Foundations for Aligning Superintelligence with Human Interests” (2014) and the AAAI paper “Corrigibility” (2015). Prior to MIRI, Nate worked as a software engineer at Google.
Senior Research Fellow
Eliezer Yudkowsky (email) is a decision theorist who is widely cited for his writings on the long-term future of artificial intelligence. His views on the social and philosophical implications of AI have had a major impact on ongoing debates in the field, and his work in mathematical logic has heavily shaped MIRI’s research agenda. He is the author of the Cambridge Handbook of Artificial Intelligence chapter “The Ethics of Artificial Intelligence” with Nick Bostrom (2014), and has written a number of popular introductions to the science of human rationality.
Benya Fallenstein (email) works on basic theoretical questions raised by the challenge of aligning advanced AI systems with human goals. These include decision- and game-theoretic problems that arise when artificial agents reason about future versions of themselves or about other, similarly powerful agents in their environment. Since joining the research team in 2014, she has spent time developing models of logical uncertainty (uncertainty about which mathematical statements are true), self-reference in higher-order theorem-proving systems, and the specification of safe AI goals. Benya holds a Bachelors in Mathematics from the University of Vienna.
Scott Garrabrant (email) earned his PhD in mathematics from UCLA studying applications of theoretical computer science to enumerative combinatorics. His main research area is in logical uncertainty, and he is the primary author of “Logical Induction” (2016), a highly general method for assigning probabilities to logical sentences. He is also interested in other aspects of logical uncertainty and counterfactuals. Scott joined MIRI’s team in December 2015.
Marcello Herreshoff (email) studied at Stanford, gaining a B.S. in Mathematics with Honors and two honorable mentions in the Putnam Mathematical Competition. He then spent five years as a software engineer at Google, where he gained a background in machine learning, before joining MIRI’s team in April 2017. His research interests include logical uncertainty and the design of reflective agents. Marcello has also volunteered with MIRI in the past to help produce results such as “Robust Cooperation in the Prisoner’s Dilemma: Program Equilibrium via Provability Logic” and “Program Equilibrium in the Prisoner’s Dilemma via Löb’s Theorem” (both 2014).
Sam Eisenstat (email) works on questions relating to the foundations of reasoning and agency. He studied pure mathematics at the University of Waterloo, where he carried out research in mathematical logic. Before joining MIRI in April 2017, he worked on automatic construction of deep learning models at Google. He currently works on logical uncertainty, and in particular is exploring analogies between current theories of logical uncertainty and Bayesian reasoning. He has also done work on decision theory and counterfactuals.
Abram Demski (email), who is joining MIRI as a research fellow this month, is completing a PhD in Computer Science at the University of Southern California. His research to date has focused on cognitive architectures and artificial general intelligence. He is interested in filling in the gaps that exist in formal theories of rationality, especially those concerned with what humans are doing when reasoning semi-formally about mathematics. Abram made key contributions to the MIRIxLosAngeles work that produced precursor results to logical induction. His other past work with MIRI includes “Generalizing Foundations of Decision Theory” and “Computable Probability Distributions Which Converge on Believing True Π1 Sentences Will Disbelieve True Π2 Sentences.”
Assistant Research Fellow
Tsvi Benson-Tilsen (email) works on the foundations of rational agency, including logical uncertainty, logical counterfactuals, and reflectively stable decision making, as well as other questions of AI alignment. Before joining MIRI as a full-time researcher, he collaborated on “Logical Induction“. Tsvi holds a BSc in Mathematics with honors from the University of Chicago, and is on leave from the UC Berkeley Group in Logic and the Methodology of Science PhD program. Tsvi joined MIRI in June 2017.
Researcher, AI Impacts
Katja Grace (email) contributes to AI Impacts, an independent research project focused on social and historical questions related to artificial intelligence outcomes. Her analyses include “Algorithmic Progress in Six Domains” (2013). She writes the blog Meteuphoric, and is sometimes a PhD student in Logic, Computation, and Methodology at Carnegie Mellon University. Katja joined MIRI in February 2014.
Research Fellow — On Leave
Andrew Critch (email) joined MIRI as a research fellow in 2015. He is currently on a two-year leave of absence to work with UC Berkeley’s Center for Human-Compatible AI. He earned his PhD in mathematics at UC Berkeley studying applications of algebraic geometry to machine learning models. During that time, he cofounded the Center for Applied Rationality and SPARC. Andrew has been offered university faculty positions in mathematics, mathematical biosciences, and philosophy, and worked as an algorithmic stock trader at Jane Street Capital. His current research interests include logical uncertainty, open source game theory, and avoiding race dynamics between nations and companies in AI development.
Chief Operating Officer
Malo Bourgon (email) oversees MIRI’s day-to-day operations and program activities. Before becoming COO, Malo worked for MIRI as a program management analyst, helping implement many of MIRI’s current systems, processes, and program activities. He also co-chairs the committee on the Safety and Beneficence of Artificial General Intelligence and Artificial Superintelligence of the IEEE Global Initiative for Ethical Considerations in Artificial Intelligence and Autonomous Systems. Malo joined MIRI in 2012 shortly after completing a master’s degree in engineering at the University of Guelph.
Program Management Analyst
Alex Vermeer (email) improves the processes and systems within and surrounding MIRI’s research team and research programs. This includes increasing the quality and quantity of workshops and similar programs, implementing best practices within the research team, coordinating the technical publication and researcher recruiting pipelines, and other research support projects. Alex holds an Engineering degree from the University of Guelph, and joined MIRI in 2012.
Research Communications Manager
Rob Bensinger (email) writes and distributes material on MIRI’s research activities. His background is in the study of scientific and religious communities, and his research interests include value theory and the relationship between philosophy and psychology. Rob joined MIRI in November 2013.
Aaron Silverbook (email) manages MIRI’s work environment. He focuses on developing, maintaining, and improving the “behind-the-scenes” systems that make the organization run like a well-oiled machine. Aaron joined MIRI in July 2016.
Colm Ó Riain
Colm Ó Riain (email) coordinates our philanthropic strategy to support MIRI’s growth plans. After 15 years working in the video game industry at companies including Electronic Arts and Activision, he moved into philanthropy work at Zynga.org and Music Team before joining MIRI in July 2016. He has a master’s degree in AI from the University of Rochester and a joint honours bachelor’s in Mathematics and Computer Science. Colm is also a professional violinist and composer.
Matthew Graves (email) writes technical material to support MIRI’s research activities. His research interests are in system design, decision-making, and machine learning. He has a master’s degree in Operations Research and worked as a data scientist at Indeed before joining MIRI in October 2016.
