Our research group has two broad areas of focus. One part of the group studies light-matter
interactions and origin of optical properties of materials using computational and
analytical models. This takes us to other areas of Physics such as statistics and
dynamics of quantum systems, occasionally. Another part of the group works in developing
computational methods for algebra. This work combines numerical mathematics with
computational solutions for scientific/engineering problems in a general way. In
addition, we work on methods of analysis for matrices and functions.
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. Some of our work is aimed at realizing new materials
or sensors. These materials and sensors can be used in diverse applications such
as biosensing and communication.
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.
