Research

Prof. Keiser is an experimental physicist whose research focuses on using terahertz frequency light to study materials. He is specifically interested in engineering new types of optical devices that interact with and use terahertz radiation.

Terahertz (THz) radiation is a type of light, more energetic than microwaves but less energetic than infrared light.  From a physics perspective, THz light is very useful for spectroscopic investigations of a range of physical phenomena in materials. From an engineering perspective, the THz frequencies are an under-used portion of the electromagnetic spectrum and can be used for faster wireless communication and data transfer. The challenge for researchers and engineers is to overcome a lack of sources, detectors, and optics for THz light.  In his research, Prof. Keiser studies ways to fill this technological gap using artificial engineered structures called metamaterials.

Before joining the faculty at Washington College, Prof. Keiser was a postdoctoral research scientist at Brown University.
