I am an Assistant Professor of Computer Science at the University of California Davis. My research is at the intersection of computer networks and public policy with an emphasis on online privacy. My work yields methodologies and analyses that provide empirical evidence on contentious questions in technology policy. I use conventional methods from both computer networking (large-scale Internet measurements) and the social sciences (surveys). My research focuses on three areas: (i) inferring capabilities for government surveillance created by the macroscopic structure of the Internet; (ii) revealing commercial surveillance enabled by consumer devices; (iii) Internet policy issues in the United States. My research in these areas is published in major Association for Computing Machinery (ACM) conferences on both cybersecurity (CCS) and networking (SIGCOMM, IMC). My studies have won several awards at computer networking conferences, including SIGCOMM Best Paper.

Prior to joining UC Davis, I was a Ford Foundation Post-Doc Fellow at Northeastern, working with David Choffnes. I received my Ph.D. in Computer Science from UC San Diego in 2021, with Alex Snoeren and Alberto Dainotti as advisors. My doctoral dissertation studied the exposure to observation and selective tampering of traffic flowing toward countries, as well as their organizations and critical sectors. 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 was also awarded the Future Faculty Fellowship and served as the Cultural and Spiritual Life Staff Affiliate, LGBTQA Resource Center. In broader academia, 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, PAM, TMA and ANRW. Before joining Northeastern, I worked for the United Nations, major tech company Akamai, and Schlumberger, a Fortune 500 company, where I served as a positioning engineer on a vessel that sailed around Europe, the Middle East, and North America. 


In my spare time, I enjoy photography, cooking, running, biking, and contemporary dance. I have also volunteered for presidential campaigns in the US and Venezuela, and visited 30 countries and over half of US states. 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.
