Mengwei Ren
Research Scientist & Photographer
I am a researcher working in generative AI, with a focus on controllability, identity preservation, and robustness in real-world settings. My work explores how people can edit, compose, and reimagine photos while staying true to real individuals and the moments they capture.
I am currently a Research Scientist at Phota Labs, where I work on personalized generative AI for photography.
Previously at Adobe, I led the development of the Harmonize feature in Photoshop — a flagship generative feature launched in 2025 and used by millions of users — enabling seamless, photorealistic compositing of people and objects into new scenes.
I received my Ph.D. in Computer Science from New York University (2023), where I worked on controllable generative models for image editing, restoration, and composition. I have interned at Adobe, Google Research, and Siemens Healthineers.
