- Self-introduction
- I am an expert on quantum phenomena and their peculiar effects in optical systems. Through my theoretical work, I have pioneered new methods of control for photons and fields. I strongly believe that a better understanding of quantum physics is possible and can be achieved by better methods of observation. At the heart of this effort is the problem of control and the limitations imposed on it by quantum uncertainty.
At present, science is suffering from a superficial understanding of empirical standards and a lack of honest discussion regarding the wider implications of new insights. To me, science is an indispensable part of our shared human heritage and we need to work together to promote and maintain a free and open exchange of scientific ideas.
I was able to move from Germany to Japan because science knows neither nationality nor boundaries. The same should apply to all other fields of academia and I believe that it is the central purpose of Universities to bring people from all backgrounds together in an honest effort to realize a life dedicated to truth and honesty. I sincerely hope that I can contribute to this effort and this is the core motivation of my work.
