Our research group has two broad areas of focus. One part of the group has studied
physics of light emission and emitter-matter interactions to develop theoretical
ideas and computational models. This takes us to other areas of Physics such as
statistics and dynamics of quantum systems, occasionally. Our theoretical work is
tested through our collaboration with experimental groups. 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 models are an essential complement and sometimes even a prerequisite to experimental
studies today, and some of this work is aimed at realizing new materials.

The other area of interest includes parts of mathematical analysis and computational
methods for algebra. Our analysis mostly uses working mathematics to minimize abstraction
even while trying to maximize generality. This work may combine mathematics and computational
solutions as general-purpose methods for scientific/engineering problems.

In the beginning there was nothing. God said, 'Let there be light!' and there was
light. Now there is still nothing, but you see it a whole lot better.
