USC · Thomas Lord Department of Computer Science

We study how humans and machines shape each other.

The HUMANS Lab — HUmans, MAchines, Networks & Social Systems — a USC group studying social bots, AI safety & human-machine societies.

A research group of the Machine Intelligence & Data Science (MINDS) initiative · directed by Emilio Ferrara

! For the upcoming PhD cycle I can only recruit students who hold an individual fellowship. If you have one and want to join us, please reach out.

What we work on

What if societies and machines are one system?

01

Social Bots & Influence Ops

Detecting automated and coordinated accounts; measuring platform manipulation at scale.

02

AI Safety & Bias Auditing

Behavioral audits of LLMs — deceptive behavior, quantization-induced bias, cultural safety.

03

Misinformation & Integrity

How false and divisive content spreads, and which interventions actually work.

04

Network Science

Community detection and diffusion — from theory to scalable open-source tools.

05

Computational Social Science

Large-scale measurement of collective behavior: elections, crises, human-AI interaction.

06

Human-Centered AI

Designing AI that serves people and communities: interaction, trust, and alignment.

INITIATIVE

The Election Integrity Initiative

Our standing election-integrity effort: public datasets, analysis, and briefings on online manipulation around the U.S. elections.
