Hi there!

I’m Esteban Carisimo, a Postdoctoral Researcher at AquaLab, a group at the Department of Computer Science of Northwestern University. My research focuses on diverse aspects of the Internet topology, including IXPs, CDNs, transit diversity, network congestion with also interdisciplinary approaches to these topics. Prior to joining Northwestern, I obtained Doctoral (2020) and Engineering (2014) degrees from Universidad de Buenos Aires, where I was also appointed as Adjunct Professor of the Department of Computer Science of the School of Engineering between 2020 and 2021.


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.
Feb 10, 2024 I am thrilled to announce that I am going to be a member of the Technical Program Committee for both TMA 2024 and IMC 2024!
Jan 30, 2024 Our guest blog post about Long-Haul Links was featured on the APNIC Blog!
