Summary#
Hello, I’m Damien Riquet, a Research Engineer with a passion for exploring innovative solutions in Cybersecurity. Welcome to my website, where I’m thrilled to share my journey, projects, and discoveries in the world of research and technology.
Since an early age, I’ve been captivated by the wonders of science and technology, driving me to pursue a career in research to actively contribute to advancements that shape our world. My journey began at the University of Lille, France, where I completed a PhD on Network Security, Language and Distribution. After that, I joined Stormshield, a network security provider, as kernel developer. Later on, I became part of Vade, an email security provider, first as Research Engineer, now as Lead Research Engineer.
My current research interests revolve around Cybersecurity, Machine Learning, and Natural Language Processing, combining insights from various fields to create meaningful and impactful outcomes.
As Lead Research Engineer at Vade, I take pride in leading innovative projects that benefit both our customers and the academic community. This includes prototyping new approaches using cutting-edge technologies like Computer Vision, Machine Learning, and NLP. Additionally, I enjoy providing insightful propositions to our customers and actively publishing our work in academic conferences.
I’m always excited to connect with fellow researchers, enthusiasts, and anyone interested in the marvels of research. If you have any questions, collaboration proposals, or just want to say hello, feel free to reach out.
About me#
Proud father of two, I live near Lille, France. I like spending time with my family, playing disc golf and video games, or finding geocaches. I also like to make jokes and puns.
I love computer science and cybersecurity. While my go-to languages are Golang and C, I’m learning Rust at the moment. I am a quick learner and always up for a good challenge.
Outside of work, I’m actively involved in various pursuits. Since 2015, I have served as a geocaching reviewer, and I currently sit on the board of my children’s kindergarten association.
Curiosity best describes me: I have a voracious appetite for knowledge, often immersing myself in articles, GitHub repositories, and educational videos to understand diverse subjects.
