Liza Tennant


I am an AI & Social Scientist looking to build moral alignment into AI. Currently studying this in agent-based simulation (e.g. Multi-Agent RL with independent learners) and foundation models (e.g. Llama), with inspiration from moral philosophy, psychology and economics.

Currently I’m a PhD candidate at the Machine Intelligence Lab, Department of Computer Science, University College London (UCL). I am conducting my PhD research on the problem of Morality - in humans and machines - funded by the Leverhulme Doctoral Training Programme for the Ecological Study of the Brain. Before my PhD I studied Psychology & Linguistics (@ UCL), conducted research on political psychology using Twitter data (@ Cambridge), and worked as an AI/Data Scientist and Behavioural Scientist at two start-ups and a large investment bank.

My research combines Artificial Intelligence with Moral Philosophy and Social Psychology. I use simulation methods, Reinforcement Learning, Game Theory and Language Models to 1) study the emergence of ethical and cooperative behaviour in multi-agent social dilemma environments, and 2) provide insights for developing morality for real-world, interactive learning & decision-making AI systems in the future. My latest project has focused on analysing multi-agent interactions between learning artificial agents that differ in their moral objective functions, trying to generate insights for behaviours and social outcomes that emerge in morally heterogeneous societies.
