Thomas A. Germer (Fed)

Dr. Germer, a researcher in the field of optics at surfaces, has been at NIST since 1992. His main interests involve the measurement and interpretation of light scattering from surfaces, optical polarization measurements, optics of structured surfaces, optical imaging theory, and general spectrophotometry.

He has received the Department of Commerce Bronze and Silver Medals, the Judson C. French Award, the NIST Chapter of Sigma Xi Young Scientist Award, and is a Fellow member of SPIE.

Dr. Germer is a member of the Sensor Science Division's Optical Properties of Materials focus program.
