Welcome to my homepage!

I am a Senior Research Fellow at the Centre for Quantum Technologies in Singapore and a visiting scientist at the University of Oxford, where I am part of the Quantum Systems Engineering group. I am a theoretical physicist working in the field of quantum physics and its applications in Quantum Technologies.

Quantum technologies aim to enhance the performance of next-generation technologies by exploiting the laws of quantum physics. Quantum physics is the branch of physics that describes the laws of nature that apply to microscopic objects which are much smaller than those of our everyday life. The typical size of these microscopic objects is a single atom, which is a basic unit of matter. Almost one hundred years after the invention of quantum physics, our increasing ability to control complex physical systems on the quantum level promises to dramatically enhance the performance of applications like sensing, metrology, communication, imaging, and computing. More details about my current research can be found here.

Footnote: You may wonder what the banner at the top of this page shows. To some it may look like an artist’s impression of Stonehenge, but it actually is the probability density of an electronic state in Hydrogen: The height of the peaks tells you how likely it is to find the electron at certain positions in a plane containing the nucleus. For the experts, the picture shows |φnlm |2 for n=15, l=12 and m=1 in the x-z plane with y=0.
