"Science is a 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, I'm interested in how the relationships between light and matter change -- qualitatively, fundamentally -- in the case of the most intense light anyone 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. My team and I have taken new physics-knowledge we've developed, and used it as a foundation to invent new kinds of laser materials-processing. We've also used the new science we've found in laser materials-processing to create new and less-invasive ways to do arthroscopic knee surgery, using rapid trains of very short pulses.***Ultra-intense laser-matter interaction: My most basic and curiosity-driven physics, needs access to the highest-intensity lasers worldwide, taking opportunities in France, the UK, and the USA, as well as at home. Our theoretical work needs access to extremely powerful multi-processor computers to run simulations, though we also work some problems with pen and paper. For some years, this has made contributions in atomic physics, nonlinear optics, relativistic laser-plasma physics and astrophysics. It has also provided the foundations of my commercially significant applied-physics research.***Applications of ultrashort-pulse intense optical physics: This foundational science program always very closely informs the applied-physics research I do, closer to home. We use the same kind of ultrafast lasers, but not scaled to the world's highest optical intensities. These lasers, of the same basic technology, we invent or buy and operate in my own laboratories. We consistently 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 career goals -- an exceptional opportunity to develop their deep understanding in physics, medical biophysics and optics, while supporting the ambition of most to contribute to society in the most important ways they can imagine.***What unifies all of these efforts -- what has created research projects funded by CHRP or NSERC-Strategic funding, led to NSERC-Engage and direct support from industrial partners, what has in turn benefitted from these other sources, and what also ties all of it together -- has been NSERC Discovery program funding.***"Des chercheurs qui cherchent, on en trouve.

“科学是一条管道”是一个概念，它经常是基本的好奇心驱动的发现研究，它提供了最终陷入创新，商业影响和社会利益的想法，理解和概念。 从最基本的角度来看，我对光与物质之间的关系如何变化感兴趣 - 从定性，根本上讲 - 在任何人都可以在地球上产生的最强烈的光线。 ***我们学到的东西以及我们在此过程中开发的技术和工具，然后我们能够利用创意创新。我和我的团队已经采用了我们开发的新物理知识，并将其用作发明新型激光材料处理的基础。我们还使用了在激光材料处理中发现的新科学来创建新的和侵入性的方法来进行关节镜的膝盖手术，并使用非常短的脉冲的快速火车进行。***超强的激光互动：我的最基本和好奇心的物理学需要访问最高的强度激光，以及弗朗西斯（France and France）的最高强度激光范围，并需要访问最高的强度激光。 我们的理论工作需要访问极其强大的多处理器计算机来运行模拟，尽管我们还在笔和纸上解决了一些问题。多年来，这在原子理，非线性光学，相对论激光 - 血浆物理学和天体物理学方面做出了贡献。 它还为我商业上重要的应用物理学研究提供了基础。我们使用相同的超快激光器，但不缩放到世界上最高的光学强度。这些激光器具有相同的基本技术，我们在我自己的实验室中发明或购买和操作。我们一直在定性地发现“处理”材料和生物学的新方法：修改结构，改变功能，减轻问题并创造新的机会，新工具，新方法。这为各种各样的学生提供了各种各样的学生，并在不同的职业目标中驱动了他们在物理，医学生物物理学和光学方面的深刻理解的同时，同时支持大多数人以最重要的方式为社会做出贡献。资料来源，以及所有这些都将所有这些联系在一起 - 已成为Nserc Discovery计划的资金。 -Charles de Gaulle
