Michael Kearns was born in 1975 in a suburb of New York City. Growing up in an environment that encouraged analytical thinking, he became interested in formal methods and probability theory during high school. Michael earned a Bachelor of Science in Computer Science from the Massachusetts Institute of Technology in 1996, followed by a Ph.D. from Stanford University in 2000. His doctoral research focused on computational learning theory, laying the groundwork for his later work in privacy and fairness.
Academic Careers
Diana Kearns
After completing her doctoral studies, Diana joined the faculty of a mid‑size university in the Pacific Northwest. She served as an assistant professor from 2000 to 2005, during which time she published several papers on clustering algorithms and their applications to social network analysis. In 2005, she accepted a tenure‑track position at a major research university, where she was promoted to associate professor in 2010 and full professor in 2015. Diana has chaired the Department of Computer Science on two separate occasions and currently directs the university’s Center for Ethical AI.
Michael Kearns
Michael began his academic career at the University of California, Berkeley, where he served as an assistant professor of Electrical Engineering and Computer Science from 2000 to 2006. He was promoted to associate professor in 2006 and to full professor in 2012. In 2014, Michael joined the faculty at the Massachusetts Institute of Technology, where he holds the title of the Michael W. Bratton Professor of Computer Science. He is also the founding director of the MIT Media Lab’s Group on Algorithmic Accountability.
Research Contributions
Diana Kearns
Diana’s research spans several intersecting domains. Her early work on clustering algorithms contributed to the development of scalable methods for high‑dimensional data, enabling more efficient community detection in large social networks. In the 2010s, she shifted focus to algorithmic fairness, investigating how bias can be measured and mitigated in predictive models. Her work on fairness metrics, including demographic parity and equalized odds, has been widely cited in both academia and industry. Additionally, Diana has contributed to privacy‑preserving machine learning, proposing techniques for differential privacy in recommendation systems.
Michael Kearns
Michael Kearns is best known for his pioneering research in differential privacy, which formalizes the privacy guarantees of algorithms that analyze sensitive data. His influential 2006 paper on private data analysis introduced the concept of “privacy‑preserving learning” and established a rigorous mathematical foundation for the field. Michael’s research also covers computational learning theory, game theory, and the economics of privacy. In recent years, he has focused on algorithmic accountability, exploring how to design systems that can be audited for fairness and transparency. His contributions have led to the publication of numerous highly cited journal articles and conference papers.
Collaborative Work
Since the early 2010s, Diana and Michael have co‑authored a series of papers that address the intersection of privacy and fairness. Their joint work on “Fairness in Privacy‑Preserving Data Release” proposes mechanisms that simultaneously protect individual privacy while maintaining equitable performance across demographic groups. They also collaborated on a study that applies game‑theoretic models to understand the incentives of data brokers, offering policy recommendations to regulators. The duo’s partnership has been highlighted in several interdisciplinary conferences, and their joint efforts have been recognized with joint awards from both the ACM and the IEEE.
Teaching and Mentorship
Diana Kearns
Diana has taught a wide array of courses, ranging from introductory programming to advanced topics in machine learning and ethics in artificial intelligence. She has developed an online MOOC titled “Algorithms for Social Impact,” which has attracted thousands of learners worldwide. Diana mentors graduate students and postdoctoral researchers, many of whom have gone on to prominent positions in academia, industry, and public policy. Her mentorship style emphasizes rigorous analytical thinking coupled with a strong sense of social responsibility.
Michael Kearns
Michael’s teaching portfolio includes core courses in machine learning, probability, and algorithm design. He is renowned for his engaging lecture style and for incorporating real‑world examples that illustrate the ethical implications of algorithms. Michael supervises a large cohort of doctoral candidates, many of whom have contributed to foundational work in privacy and fairness. He also serves as an advisor to several research groups focusing on AI ethics, and he frequently presents workshops that help practitioners implement privacy‑preserving techniques in industry.
