It is impossible to observe all the bright and brilliant colours in nature without demanding explanation! My research focuses on understanding the optical mechanisms governing colouration in natural photonics and biomimetic ditto. My work takes outset in Maxwell's equations from which light propagation and interaction is studied. This involves numerical simulations using FEM, FDTD and the transfer matrix method for multilayers and spherical particles. Theories not directly complying with Maxwell's equations like radiative transfer and scalar diffraction theory are also used when appropriate.
At the moment I work on understanding light reflection from flower petals and bacteria formations.
