Greetings! I'm Diwang. I'm a PhD student researching novel program analysis methods to make our web technologies more secure, private, and reliable. I reside at the Department of Computer Science of Johns Hopkins University, advised by Prof. Yinzhi Cao.

Previously, I had the privilege to work with Prof. Soudeh Ghorbani on network verification and Prof. Ryan Huang and Prof. Haryadi Gunawi on distributed systems reliability. I graduated from Institut Teknologi Bandung, Indonesia in 2020 with Cum Laude distinction.

Research

My current research interest revolves around two topics regarding web security and program analysis:

• Exposing how classic vulnerabilities could be reintroduced in new runtime (e.g. frontend JS framework).
• Using machine-learning based method to plug the holes in JavaScript static analysis tool's taint rule.

Misc Interests

• Journalism: Blogging and journalism in general are the thing that gets me into writing. Some of my favorites are Stratechery, Asianometry, and Vitalik's Although different from the world of academia (here's a good video essay about it), they're also a vital part of mass communication and also cathartic when done right. Check out my blog, blog.diwangs.dev!

• Homelab: I enjoy managing my own IT infrastructure and learning to make it more secure and reliable. Skin in the game! (NixOS, btw)

• Games: Like the stereotypical CS student, I enjoy playing video games. Mostly FPS (Valorant, anyone?) and city-building games.
