A] A multi-layered sphere with defective inclusions irradiated by laser beam - Distribution of radiation on an imaginary far-field spherical surface around it

B] Distribution of energy in a metal-dielectric hybrid material when irradiated (laser beam along z axis)

A major part of the group studies the behavior of light and light-matter interactions using computational and analytical models.  With light “what we get is what we see”, meaning its apparent behavior heavily depends on its parameters measured and on the spatial, time and energy scales of its interaction with matter. Hence computational models are an essential complement and sometimes even a prerequisite to experimental studies today.  Some of our work is aimed at realizing new materials or sensors.  The materials and sensors can be used in diverse applications such as biosensing and communication.  Fundamental studies of light-matter interactions that in turn may have potential applications in sensing, communication and computing are explored as well.

Another part of the group works in developing computational formulations for physics and methods for matrix algebra.  This work combines applied mathematics with computational resources to create solutions for computation intensive scientific/engineering problems in general.

In the beginning there was nothing. God said, 'Let there be light!' And there was light. There is still nothing, but you see it a whole lot better......- A comedians take on the Universe.
