About
I am a computer vision scientist interested in remote sensing applications in industry, environment and development.
I have publications in top computer vision conferences (including ECCV, ICCV, BMVC), and even won a best paper award at an ECCV workshop in 2020. I have also been a reviewer for many computer vision conferences, and was awarded an outstanding reviewer award at CVPR 2023.
Currently, I am working as a lead AI scientist in remote sensing for the company Amphitrite.
My PhD is in computer vision and was granted by the University of Paris-Saclay in 2023. I worked on Sign Language translation with Annelies Braffort, Michèle Gouiffès, Gül Varol and Andrew Zisserman.
Prior to my PhD, I graduated from the MVA program at the ENS Paris-Saclay.
I also studied mathematics (joint degree at ANU and NUS) and economics (Paris School of Economics), and spent 2 years working as a Data Scientist in a software start-up (Explain).
