The existence of a circumsolar dust ring composed of particles trapped in resonance with the Earth orbit has been known for a few decades now. A circumsolar ring near the orbit of Venus was only discovered a few years ago. Together with Grant Kennedy, I studied this ring in detail, developing a pipeline to reduce STEREO images and comparing the structure of the observed rings with theoretical expectations from models. We found that the models predicted the existence of dust in j:j+1 resonance for high j, which does not agree with the observed spatial distribution of the ring.
One of my undergraduate summers was spent at Forschungszentrum Juelich in Germany on a DAAD Rise scholarship. I studied the suitability of certain materials such as hexabenzocoronene for use in molecular spintronics using Atomic Force Microscopy and Scanning Tunneling Microscope.
While I was a high school student in Singapore, I was awareded a Science Research Program (SRP) fellowship at National University of Singapore. I used this year long research fellowship to study the phase transformation of Iron-Oxy-Hydroxide under a laser beam with Prof Sow Chorng Haur. This project gave me invaluable hands on experience in using Raman spectroscopy, Scanning Electron Microscope, and Fourier Transform Infrared Spectroscopy to study thin layers of material and their interaction with laser light. I presented this work at the Science Research Congress at NUS in 2012.
