About
During my adolescence, I developed a strong interest in video game development which led me to acquire a solid knowledge in various scientific domains related to computer science, including real-time rendering, optimization, 3D rendering engines, sockets, and operating systems. As I worked on building my own game 15 years ago, I discovered a deeper fascination with the underlying mechanics of game development, which drove me to develop my own complete game engine. This engine features a custom 3D engine, integrated physics, post-processing (shader), sound, scripting, editor, and server, all programmed in c++ 11. Through this self-learning journey, I have honed my problem-solving skills and increased my programming proficiency, making me more adaptable to new challenges. Eventually, I pursued a master's degree in Image Analysis and Computer Graphics.
After completing my master's degree in Image Analysis and Computer Graphics, I continued my academic journey and obtained a PhD in the same field. This provided me with a specialized expertise in deep learning and hyper-parameter optimization, applied to image analysis, including hyper-spectral data, image segmentation, object detection, and tracking. Through my research, I have developed a comprehensive understanding of advanced image analysis techniques and their practical applications. This knowledge has proven invaluable in my work as a computer scientist, allowing me to stay on the cutting edge of technological advancements and to provide innovative solutions to complex problems.

Ecology, biodiversity, and agriculture have been long-standing passions of mine, especially when it comes to the idea of doing things oneself and achieving a sense of autonomy. These interests were instilled in me from a young age and have shaped my personal projects, skills, and knowledge in this field. As a researcher, I have less time to dedicate to these pursuits, but I am always eager to engage in discussions surrounding these topics.
At first glance, the intersection of technology and autonomy may appear contradictory. However, I firmly believe in striking a balance between the two, keeping our head in the clouds while remaining grounded. While technology can be fascinating and enable incredible achievements, it is important to recognize its costs and the barriers to access it that exist for those who are economically disadvantaged. Thus, I believe that the best technology is that which is open source, free, and easily reproducible with a low energy cost and minimal ecological impact, in order to respect both nature and future generations.
