I am a Ford Foundation Fellow at Northeastern University's Khoury College of Computer Sciences, mentored by David Choffnes. My technical expertise is primarily on wide-area networking and routing. My research interests lie at the intersection of Internet measurement, cybersecurity and privacy, and technology policy. 

My doctoral dissertation studied the exposure to observation and selective tampering of traffic flowing toward countries, as well as their organizations and critical sectors. My Ph.D. advisors at CAIDA-UCSD were Alex Snoeren and Alberto Dainotti. My colleagues and I created metrics to analyze BGP routing announcements and traceroute-inferred AS paths. During my doctoral studies, I received Microsoft Research’s Dissertation Grant and served on the board of UCSD’s Graduate Women in Computing to advance diversity in the field.

At Northeastern, I have been awarded the Future Faculty Fellowship, and I'm affiliated with the Mon(IoT)r Lab. In wider academia, my research has been published at PAM (winning Best Dataset Award at PAM 2022), ACM CCS, ACM IMC, and ACM SIGCOMM (winning Best Paper at SIGCOMM 2018). I have worked as an external reviewer for refereed publications ACM SIGCOMM CCR and Performance Evaluation, and served on the Technical Program Committee for IMC 2022 and PAM 2022.

Before joining Northeastern, I worked for the United Nations and Schlumberger, where I served as a positioning engineer on a vessel that sailed around Europe, the Middle East, and North America. In 2019, I worked on detecting data exfiltration requests as a security software engineering intern at Akamai. I have also volunteered for presidential campaigns in the US and Venezuela, and visited almost 30 countries and over half of US states.


In my spare time, I enjoy photography, cooking, running, biking, and contemporary dance. The header image was taken at Parque 3 de Febrero in Buenos Aires, Argentina. My all-time favorite quote is from a poem by Antonio Machado: "Caminante, no hay camino, se hace camino al andar" (Traveler, there is no road; you make your own path as you walk). My pronouns are he/they/él.


  • Jul. '22. I was awarded the Ford Foundation Postdoctoral Fellowship by the National Academy of Sciences. Northeastern Khoury News interviewed me on this award and the underlying research we proposed that is focused on the digital divide.

  • Jun. '22. Honored to be featured in the IEEE Computer Society's Pride in STEM interview series.

  • May '22. We answer frequently asked questions about the Your Echos are Heard paper on the project website.

  • Mar. '22. My co-authors and I were honored to receive the Best Dataset Award at the Passive and Active Measurement Conference (PAM).

  • Jan. '22. Thrilled by Profs. David Choffnes' and Theo Benson's invitation to serve to serve on the Technical Program Committee of the Internet Measurement Conference (ACM SIGCOMM IMC).

  • Dec. '21.  A paper largely based on my doctoral thesis was accepted to appear at the Passive and Active Measurement Conference (PAM '22).

  • Nov. '21. I am honored to serve on the PAM Program Committee

  • Nov. '21. We hosted an IMC "Pod" at Northeastern.

  • Aug. '21. Our submission "Identifying ASes of State-Owned Internet Operators" was accepted to IMC 2021.

  • Aug. '21. I defended my doctoral dissertation. Grateful to the committee members (Profs. Stefan Savage, Aaron Schulman and Margaret Roberts, along with my advisors) for their time and valuable feedback.

  • April '21. Honored to have been awarded Northeastern University's Future Faculty Fellowship (Postdoctoral). 

  • In 2019, Microsoft Research named me a recipient of their Dissertation Grant. Very honored that our proposal was among 11 selected from over 200. More info at MSR.

  • In 2018, my co-authors and I were honored to be awarded the SIGCOMM Best Paper Award.
