Senior Research Scientist

Google Brain

Social learning helps humans and animals rapidly adapt to new circumstances, and drives the emergence of complex learned behaviors. My research is focused on Social Reinforcement Learning—developing algorithms that combine insights from social learning and multi-agent training to improve AI agents’ learning, generalization, coordination, and human-AI interaction.

I am currently a Senior Research Scientist at Google Brain. From 2020-2022 I held this position jointly with a Visiting Postdoctoral Scholar position at UC Berkeley, in Sergey Levine’s group. Before that, I received my PhD from MIT, where I worked on Affective Computing and deep/reinforcement/machine learning in Rosalind Picard’s group. I have interned at DeepMind, Google Brain, and worked as an OpenAI Scholars mentor.

I will be joining the University of Washington School of Computer Science as an assistant professor starting in January 2024. If you are interested in joining my lab as a PhD student, please consider applying to UW! Be sure to mention my name in your application.

Social Influence as Intrinsic Motivation for Multi-Agent Deep Reinforcement Learning

Social influence is a unified mechanism for achieving coordination and communication in Multi-Agent Reinforcement Learning, through rewarding agents for having causal influence over other agents’ actions, thus increasing mutual information between agents’ actions. Optimizing for influence leads to agents learning emergent communication protocols. Unlike prior work, influence can be computed in a fully decentralized manner.

Concept-based Understanding of Emergent Multi-Agent Behavior
Interpreting whether multi-agent reinforcement learning (MARL) agents have successfully learned to coordinate with each other, versus finding some other way to exploit the reward function, is a longstanding problem. We develop a novel interpretability method for MARL based on concept bottlenecks, which enables detecting which agents are truly coordinating, which environments require coordination, and identifying lazy agents.

Moral Foundations of Large Language Models

In the ZONE: Measuring difficulty and progression in curriculum generation
Past work on curriculum generation in RL has focused on training a teacher agent to generate tasks for a student agent that accelerate student learning and improve generalization. In this work, we create a mathematical framework that formalizes these concepts and subsumes prior work, taking inspiration from the psychological concept of the Zone of Proximal Development. We propose two new techniques based on rejection sampling and maximizing the student’s gradient norm that improve curriculum learning.

Model-free RL agents fail to learn from experts present in multi-agent environments. By adding a model-based auxiliary loss, we induce social learning, which allows agents to learn how to learn from experts. When deployed to novel environments with new experts, they use social learning to determine how to solve the task, and generalize better than agents trained alone with RL or imitation learning.

Understanding attention to adaptive hints in educational games: an eye-tracking study
This study uses eye tracking to assess how students interact with automatic, adaptive hints in an Intelligent Tutoring System. Specifically, we study Prime Climb, an educational game which provides individualized support for learning number factorization skills in the form of hints generated from a model of student learning.

Featured Talks

Adaptive Learning Agents workshop at AAMAS
This talk gives an overview of Social RL and dives into three topics: multi-agent social influence, emergent curriculum generation with PAIRED, and emergent social learning and PsiPhi-Learning. It is similar to the faculty job talk I gave at MIT.
2022 Virtual
Institute for Pure and Applied Mathematics (IPAM) Mathematics of Intelligence workshop
This talk focuses on how social learning from other agents can lead to learning more complex behaviors and enhance generalization. I discuss PAIRED and recent work on emergent social learning and PsiPhi-Learning in detail.
