"Science in the Pipeline" is the concept that more often than not it's basic curiosity-driven discovery research that supplies the ideas, the understanding, and the concepts which eventually make their way into innovation, commercial impact and social benefits. My research, with my team members, begins with the science of the interaction between extremely short pulses of intense laser light and matter. At its most basic, we're interested in how the relationships between light and matter change -- qualitatively, fundamentally -- in the case of the most intense light we can produce on Earth. The things we learn, and the techniques and tools we develop along the way, we're then able to use towards creative innovations, new applications in things like advancing the best of materials-processing, or developing new approaches to the treatment of cancer or less-invasive kinds of surgery for heart-valve repair. For our experimental work, we need access to the highest-peak-power lasers available worldwide, and we seek opportunities in France, the UK, the USA, as well as at home. Our theoretical work needs access to powerful multi-processor computers to run simulations, though we also work with pen and paper. For applications we use the same kind of ultrafast lasers, but downscaled to systems we can operate in my own laboratories. We discover qualitatively new ways to 'treat' materials and biotissues: modifying structure, changing functionality, mitigating problems and creating new opportunities, new tools, new approaches. This gives students of all kinds, and driven by different goals, an exceptional opportunity to develop their deep understanding in physics, medical biophysics and optics, while supporting their ambition to contribute to society in the most important ways they can imagine.

“管道中的科学”这个概念通常是由好奇心驱动的基本发现研究，提供最终转化为创新、商业影响和社会效益的想法、理解和概念。 我和我的团队成员的研究始于强激光极短脉冲与物质之间相互作用的科学。 最基本的是，我们感兴趣的是在地球上产生的最强烈的光的情况下，光和物质之间的关系如何从质上、根本上发生变化。 我们学到的东西以及我们一路上开发的技术和工具，然后我们就能够将其用于创造性的创新、新的应用，例如推进最好的材料加工，或开发治疗癌症或癌症的新方法。用于心脏瓣膜修复的微创手术。 对于我们的实验工作，我们需要使用全球最高峰值功率的激光器，并且我们在法国、英国、美国以及国内寻找机会。 我们的理论工作需要使用强大的多处理器计算机来运行模拟，尽管我们也使用笔和纸。 对于应用，我们使用相同类型的超快激光器，但缩小到我们可以在自己的实验室中操作的系统。我们发现“处理”材料和生物组织的新方法：修改结构、改变功能、缓解问题以及创造新机会、新工具、新方法。这为各种目标不同的学生提供了一个难得的机会，让他们加深对物理学、医学生物物理学和光学的理解，同时支持他们以他们能想象到的最重要的方式为社会做出贡献的雄心。 “Des chercheurs qui cherchent，on en trouve。Des chercheurs qui trouvent，on en cherche。” ——戴高乐 “研究人员寻找，我们找到这些；研究人员发现，我们寻找这些。” ——戴高乐
