I'm a PhD student at The University of Tokyo under the supervision of Professor Hideki Nakayama.

I'm generally interested in computer vision and generative models, both from a theoretical and applied perspective. In particular, I've been working on/interested in the following areas:

  • Diffusion and Flow-based Models
  • Multimodal Layout Generation
  • Image Processing and Editing
  • World Models and Video Prediction

As part of a double master's degree program, I graduated from RWTH Aachen University (supervised by Professor Jens-Rainer Ohm) and Keio University (supervised by Professor Yoshimitsu Aoki).

During my internships at Rakuten Institute of Technology, Preferred Networks, LY Corporation, and Adobe Research I was able to gain valuable experience as a research scientist. I have also been collaborating with researchers from CyberAgent AI Lab on a joint research project.

I expect to finish my PhD in September 2026 and am open to job or internship opportunities.

Research

clean-usnob LayoutFlow: Flow Matching for Layout Generation
Julian Jorge Andrade Guerreiro, Naoto Inoue, Kento Masui, Mayu Otani, Hideki Nakayama
ECCV, 2024
Project Page / Code

Flow Matching for Layout Generation provides a more geometrically intuitive approach, while also significantly speeding up the generation process.

clean-usnob PCT-Net: Full Resolution Image Harmonization Using Pixel-Wise Color Transformations
Julian Jorge Andrade Guerreiro, Mitsuru Nakazawa, Bjorn Stenger
CVPR, 2023
Code

We enable efficient full-resolution Image Harmonization by introducing pixel-wise color transformations (PCTs). Work was done while interning at Rakuten Institute of Technology.

clean-usnob Detection of Osteoarthritis from Multimodal Hand Data
Julian Jorge Andrade Guerreiro, Yoshimitsu Aoki, Shuntaro Saito, Katsuya Suzuki
EMBC, 2022

We investigate the effectiveness of different modalities, namely RGB images, video, and thermal images, to detect Osteoarthritis.
