Margo Seltzer, the Canada 150 Research Chair in Computer Systems at the University of British Columbia and 2023–2024 ACM Athena Lecturer, is the kind of researcher who stands out not just for her accomplishments, but for her tirelessness. After building a database software library that underpinned many first-generation Internet services, she worked on topics that range from file systems and storage to capturing and accessing data provenance. Here, she speaks with Leah Hoffmann about finding impactful research projects--and keeping up with everything that's going on in the field. The story of Berkeley DB, the database software library that you built with Keith Bostic and Mike Olson, has been told before at greater length, but let me see if I can summarize. Your work on packages such as hash and B-tree was released with Berkeley Unix as the DB 1.85 library.

Social cognition is a key feature of human-level intelligence. However, social reasoning faculties are rarely included in cognitive systems. To encourage research in this direction, we introduce a practical, computational framework that enables socially aware inference. We demonstrate the framework's ability to model a common, complex, and under-investigated aspect of human social behavior: deception. Moreover, we show how a system implementing this framework could dynamically respond once it has detected a lie. We then discuss some of the challenges associated with deception, ending with an outline of future research directions.
