profile

I am an Assitant Professor of Information Systems in the W. P. Carey School of Business at Arizona State University.

My research develops models of resilience in AI-enabled socio-technical systems, focusing on how network structure, algorithmic agents, and information dynamics jointly determine systemic resilience of socio-technical systems.

I am also affiliated with the AI and Data Analytics Center.

I hold a Ph.D. from Cornell University; where I had the fortune to be advised by Jon Kleinberg. My thesis can be found here.

My research focuses along three main streams:

  1. Algorithmic Agents and System Dynamics. I explore how do intelligent agents alter coordination, amplification, and systemic stability in digital environments. Recent examples include studying network dynamics (PNAS Nexus 2025, Featured by TechXplore, Featured by SingularityHub) with LLM agents, and collective decision-making (ACM CSCW 2025, ACM Featured Article).
  2. Information Diffusion and Contagion. I explore how information spreads and how cascades generate fragility, as well as how to remediate it. Examples include financial contagion (ACM WWW 2022, ACM WWW 2023, SSRN 2024, Federal Reserve Bank of Minneapolis Featured Article, TOC4Fairness), supply chains (SSRN 2024), and social networks (WWW 2026).
  3. Trust, Privacy, and Governance in Data-Driven Systems. I explore how can digital systems be designed to preserve trust and maintain stability under strategic and informational constraints. Examples include learning under information privacy (IISE Transactions 2025, ISE Magazine Featured Article, Pitt News Article, arXiV 2024).

In the past, I have closely collaborated with the Office of Applied Research at Microsoft Research, and the User Modeling Research Team at Twitter Cortex (now X), and have also contributed to the open-source statistical sampling software volesti.

My research has been supported by an Onassis Scholarship, a LinkedIn Ph.D. Fellowship, a grant from the A.G. Leventis Foundation, a grant from the Gerondelis Foundation, and a Cornell University Fellowship.
