Research

Ever since doing the switch from aerospace to fundamental science, my interest has been the study of light-matter interactions in the living system. I shaped/chose all three PhD projects listed below to acquire the research skills to pursue that interest:

  • molecular biology
  • advanced optics
  • theoretical physics
The article listed below gives some idea of my interest although it is at whole system level rather than at the cellular, subcellular level, where I work.

Over the last year, I have been working under an A*STAR grant in Singapore where I discovered quantum coherence effects in the rod photoreceptor cell. This was achieved by building and optimizing an optics and electrophysiological setup, and developing a software to precisely control and monitor all aspects of the experiment. By combining experimental observations with quantities derived from two theoretical models of phototransduction, I was able to hypothesise and verify the occurrence of quantum effects in the lab.
