Portrait of Sepehr Ilami

Sepehr Ilami

PhD Student in Industrial Engineering • Northeastern University

Welcome! I'm a third-year PhD student in the department of Industrial Engineering at Northeastern University. My research lies in Computational Social Science, Collective Behavior, and Multi-agent decision-making. I'm fortunate to be be advised by Babak Heydari. Previously, I got my BSc in Computer Engineering at Aryamehr (Sharif) University of Technology in Iran, where I was born and raised.

Research

My research is in Network Science and Multi-Agent Systems. I explore how intelligent entities—either humans or AI agents—coordinate and influence each other in networked environments. I work across two main areas:

Multi-agent LLM systems

Building frameworks for distributed AI agents to collaborate, share information, and make collective decisions; studying incentives, governance, and robustness in agent societies.

Human mobility & collective behavior

Modeling how people move through networks and interact in urban settings; analyzing coordination, compliance, and emergent patterns during routine and high-stakes situations.

My work sits at the intersection of computer science, social science, economics, and statistics—broadly described as network science.

Research Projects

Network opacity framework for The Architecture of Illusion project
ArXiv Preprint • 2026

The Architecture of Illusion: Network Opacity and Strategic Escalation

We study how strategic actors exploit hidden network structure to shape escalation dynamics. The analysis connects information shielding and perceived connectivity to when conflicts intensify or stabilize.

Authors: R. Ebrahimi, Sepehr Ilami, Babak Heydari, I. Trevino, and M. Franceschetti.

Paper
Adaptive information modulation framework for multi-agent AI governance
Journal Article • 2026

Adaptive Information Modulation: Designing Governance Mechanisms for Multi-Agent AI Systems

We design governance mechanisms that adaptively shape information exposure among AI agents. The framework aligns incentives, improves coordination, and is validated through multi-agent simulations.

Authors: Q. Chen, Sepehr Ilami, N. Lore, and Babak Heydari.

Paper
Mobility network structure figure for epidemic forecasting project
ArXiv Preprint • 2025

Network Topology Matters, But Not Always: Mobility Networks in Epidemic Forecasting

We examine when mobility network structure meaningfully improves epidemic forecasts. The results show which topological features help prediction and when aggregate mobility is sufficient.

Authors: Sepehr Ilami, Q. Cao, and Babak Heydari.

Paper
LLM fine-tuning workflow for strategic reasoning transfer
ArXiv Preprint • 2024

Large Model Strategic Thinking, Small Model Efficiency: Transferring Theory of Mind in Large Language Models

We transfer theory-of-mind reasoning from large language models to smaller, efficient models. The study benchmarks strategic decision-making improvements while reducing computational cost.

Authors: N. Lore, Sepehr Ilami, and Babak Heydari.

Paper
AI-driven COVID-19 diagnosis workflow using medical imaging
Book Chapter • 2022

COVID-19 Diagnosis with Artificial Intelligence

We develop AI-driven diagnostic systems for rapid COVID-19 screening using CT scans and X-rays. The pipeline combines model design, rigorous validation, and explainability to support clinical reliability, while extending to resource management, remote monitoring, and contact tracing.
