ABOUT ME

I am a PhD candidate in Computer Science at USC. I work in the Institute for Robotics and Intelligent Systems, supervised by Prof. Gerard Medioni. In the past, I also collaborated with Dr. SriniVas Sadda at the Doheny Eye Institute UCLA.

I received my "diplome d'ingenieur" (MS) from the Paris Institute of Technology. My Master's thesis was supervised by Prof. Jean-Luc Dugelay at EURECOM and received the best Master's thesis award by the Mines-Télécom Foundation in 2012.

RESEARCH INTERESTS

My research focuses on computer vision, computer graphics and machine learning. I address image registration and 3D reconstruction problems.
I work with many types of imagery, including medical 2D and OCT images, traditional cameras and RGB+D cameras.
Recently, I have taken interest in applying deep learning concepts to computer graphics.

PROJECTS

3D FACE MODELING

We aim at reconstructing high-resolution 3D face models for unconstrained videos. We work with both RGB+D sensors and traditional cameras. Notably, we work with low-resolution videos that established technologies handle poorly.

3D FACE RECOGNITION

We aim at leveraging 3D data for face recognition tasks. We develop end-to-end deep learning methods for this purpose and study which factors impact recognition performance.

MULTIMODAL RETINAL IMAGE REGISTRATION

We aim at performing registration of retinal data across modalities and time automatically. This step is needed by ophthalmologists to formulate diagnosis and monitor disease evolution.
