"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”的概念是，通常是基本的好奇心驱动的发现研究提供了想法、理解和概念，最终将其转化为创新、商业影响和社会效益。*我和我的团队成员的研究始于极短的强激光脉冲与物质之间的相互作用的科学。在最基本的情况下，我感兴趣的是光和物质之间的关系如何变化--定性地，从根本上--在地球上任何人都能产生的最强烈的光的情况下。*我们学到的东西，以及我们在此过程中开发的技术和工具，然后我们就能够用于创造性的创新。我和我的团队采用了我们开发的新物理知识，并将其作为发明新型激光材料加工的基础。我们还利用在激光材料加工中发现的新科学，创造了新的、侵入性更小的膝部手术方法，使用快速的极短脉冲序列。*超强激光与物质的相互作用：我最基本、最好奇的物理学，需要获得世界各地最高强度的激光，在法国、英国、美国以及国内都有机会。我们的理论工作需要使用非常强大的多处理器计算机来运行模拟，尽管我们也需要使用笔和纸来解决一些问题。多年来，它在原子物理、非线性光学、相对论激光等离子体物理和天体物理方面做出了贡献。它还为我的具有商业意义的应用物理研究提供了基础。*超短脉冲强光物理的应用：这个基础科学计划总是非常密切地向我所从事的应用物理研究提供信息，离我更近。我们使用的是相同类型的超快激光，但没有达到世界上最高的光学强度。这些激光器，拥有相同的基本技术，我们发明或购买，并在我自己的实验室操作。我们不断发现‘治疗’材料和生物组织的定性新方法：修改结构、改变功能、减轻问题并创造新机会、新工具、新方法。在不同职业目标的驱动下，这为各类学生提供了一个难得的机会，让他们加深对物理学、医用生物物理学和光学的深刻理解，同时支持MOST以他们能想象到的最重要的方式为社会做出贡献的雄心。*将所有这些努力结合在一起的是NSERC发现计划的资金--它创造了由CHRP或NSERC资助的研究项目，导致了NSERC-Engage和来自行业合作伙伴的直接支持，而这些资源反过来又受益于这些来源，也将所有这些来源联系在一起。*我爱你，我爱你。“--戴高乐
