Hi there!

I am Esteban Carisimo, a Postdoctoral Researcher at AquaLab, a group in the Department of Computer Science at Northwestern University. My research focuses on Internet topology and infrastructure, with an emphasis on the role of governments in connectivity and content delivery. I am particularly interested in Submarine Cable Networks (SCNs), Internet Exchange Points (IXPs), Content Delivery Networks (CDNs), transit diversity, and network congestion. My work aims to enrich the public debate on digital connectivity with evidence-based insights. Being born in Latin America influences my research, particularly regarding the Internet’s evolution in the region. I earned my Doctoral (2020) and Engineering (2014) degrees from Universidad de Buenos Aires, where I was an Adjunct Professor in the Computer Science Department of the School of Engineering from 2020 to 2021.


Jun 17, 2024 Excited to share that we have two posters accepted at SIGCOMM 2024
May 04, 2024 Thrilled to announce that our paper on the consequences of Venezuela’s 🇻🇪 crisis on its Internet infrastructure will appear at SIGCOMM 2024
Feb 26, 2024 I’ve developed a toolkit utilizing CAIDA’s PyBGPStream library for in-depth analysis and anomaly detection within the BGP announcements. The project is available on GitHub and can be found in this repository.
Feb 24, 2024 I have created a utility leveraging CAIDA’s PYIPMeta and the RouteViews prefix-to-AS snapshots to simplify the process of mapping IP addresses to Autonomous System Numbers (ASNs). The project is hosted on GitHub and can be accessed at this repository.
Feb 16, 2024 Our interdisplinary work exploring the interplay between network topology and the state ownership of Internet providers within autocratic regimes has been published in PNAS Nexus.
