Arthur Borem

Arthur's face Hi! I’m a final-year Computer Science PhD at UChicago researching privacy, advised by Blase Ur. I've spent my time here designing, building, and evaluating consumer-facing privacy systems. Most recently, I worked with the Data Transfer Initiative to build and publish a library for executing data transfer/portability requests (check out Pardner).

I'm also a full-stack software engineer and have worked at Asana, Lyft, and Bank of America.

I'm graduating with my PhD in June of 2026 and am looking to go back to industry, but am open-minded about what role I'd be taking on! Having said that, I'm interested in privacy engineering, product-focused software engineering, and research roles. If my research and experience sound like they could be a good fit, I'd be happy to chat. Send me an email!

Visualizer for Data Subject Access Requests

I’m building a web tool for consumers who wish to explore and aggregate their personal data from making a Data Subject Access or Portability Request. It runs fully on the client-side and is platform agnostic.

User study on enacting Data Subject Rights

After developing a data annotation web-app, I ran a user study with online consumers from around the world. They explored their data using the tool I built and noted things they found surprising or creepy. They were often overwhelmed and confused, but felt more trust toward the platforms the more transparency they were given. Watch my talk or read the full paper if you want to learn more!

Ad transparency systems taxonomy and evaluation

Analyzed 22 online ad transparency platforms (e.g., Google’s My Ad Center) and built a taxonomy listing every feature and affordance and which platforms implemented them. Then ran a user study where we asked around 200 participants to try to find specific settings and asked them about the process. Many of them were dissatisfied and found the existing systems overly complex, but also lacking key details. Read the full paper!

Fixing websites broken by ad-blockers and tracking protection browser extensions and tools

Built taxonomy for ways privacy extensions break websites by analyzing thousands of browser extension marketplace reviews for a dozen privacy extensions. After running a user study, identified the top ways users react when this happened to them. Based on this info, we are working on a solution that detects breakage by analyzing downstream effects of fetching and blocking specific resources. Read the paper on the taxonomy for more details!


Bio

I was born and raised in Belo Horizonte (Brazil) and moved to the U.S. during my junior year of high school! I then went to Brown University where I graduated with a B.S. in Computer Science. While there, I was involved in research projects with Seny Kamara (applied cryptography), Phil Klein (fair census redistricting), and Christina Smith (pedagogy in higher education). I also did software engineering internships at Bank of America Merrill Lynch and Lyft.

After Brown, I was a full-stack software engineer at Asana. There I revamped the Do Not Disturb feature, launched Messaging, maintained email infrastructure, and built the transcription generation pipeline for Video Messages, which won us a Fast Company award!

Then I moved to Chicago to start my PhD.


In addition to working on online data privacy and data access/portability, I’m a huge fan of movies, learning languages (Spanish, Italian, and, most recently, Chinese!), crocheting, and running.
