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.  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.  Fundamental studies of light-matter interactions that we perform may in turn have potential applications in lighting, sensing, communication and computing of the future.

 

Another part of the group works in developing numerical methods for algebra.  This work combines numerical mathematics with computational solutions for scientific/engineering problems in a general way.

 

 

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.
