About Me

Hello, I'm Tianran Zhang (I also go by Ran). I grew up in Beijing, China and currently live in Providence, Rhode Island. I am a junior at Brown University, studying computer science. I love technology and its interdisciplinary applications. I am passionate about human-centered design, full stack development, and machine learning and AI.


Ink Simulation

C++, Blender

Physics-based simulation of ink particle diffusion in water. Achieved by solving incompressible Navier-Stokes equations and computing ink movement using the RK2 method at each timestamp.


Secure Group Chat

C++, CryptoPP, Boost

A multi-user chat system with encrypted messaging and protected group structure from adversaries. Incorporated robust cryptographic operations including Diffie-Hellman key exchange, digital signature, and two-factor authorization.


Interactive Escape Room

C++, OpenGL

An interactive dungeon escape room rendered using trimesh, phong lighting, camera movements. Featuring shadow mapping, depth of field, anti-aliasing, and collision detection.
