Title: The Ethical Algorithm

Abstract: Many recent mainstream media articles and popular books have raised alarms over anti-social algorithmic behavior, especially regarding machine learning and artificial intelligence. The concerns include leaks of sensitive personal data by predictive models, algorithmic discrimination as a side-effect of machine learning, and inscrutable decisions made by complex models. While standard and legitimate responses to these phenomena include calls for stronger and better laws and regulations, researchers in machine learning, statistics and related areas are also working on designing better-behaved algorithms. An explosion of recent research in areas such as differential privacy, algorithmic fairness and algorithmic game theory is forging a new science of socially aware algorithm design. I will survey these developments and attempt to place them in a broader societal context. This talk is based on the book The Ethical Algorithm, co-authored with Aaron Roth (Oxford University Press).

    Title: Privacy Threats in Intimate Relationships

    Abstract: This talk provides an overview of intimate threats: a class of privacy threats that can arise within our families, romantic partnerships, close friendships, and caregiving relationships. Many common assumptions about privacy are upended in the context of these relationships, and many otherwise effective protective measures fail when applied to intimate threats. Those closest to us know the answers to our secret questions, have access to our devices, and can exercise coercive power over us. I survey a range of intimate relationships and describe their common features. Based on these features, I explore implications for both technical privacy design and policy, and offer design recommendations for ameliorating intimate privacy risks. [Joint work with Bruce Schneier]

    Bio: Karen Levy is an assistant professor in the Department of Information Science at Cornell University, and associate member of the faculty of Cornell Law School. She researches how law and technology interact to regulate social life, with particular focus on social and organizational aspects of surveillance. Much of Dr. Levy's research analyzes the uses of monitoring for social control in various contexts, from long-haul trucking to intimate relationships. She is also interested in how data collection uniquely impacts, and is contested by, marginalized populations.

    Dr. Levy is also a fellow at the Data and Society Research Institute in New York City. She holds a Ph.D. in Sociology from Princeton University and a J.D. from Indiana University Maurer School of Law. Dr. Levy previously served as a law clerk in the United States Federal Courts.
