After receiving his doctoral degree in optics, Gaeta remained at the University of Rochesterfor two years as a postdoctoral research associate. He joined the Cornell faculty in 1992. He received Young Investigator Awards from the Office of Naval Research in 1993, and from the Army Research Office in 1995. He was a recipient of theCollege of Engineering Teaching Award in 1997 and 2000.  He is a fellow of the Optical Society of America and of the American Physical Society.  

Research Interests

Our research is concerned with the interaction of intense laser light with matter. We are currently undertaking experimental and theoretical research in several areas of quantum and nonlinear optics, including nonlinear propagation of femtosecond laser pulses in optical materials and fibers, nonlinear interactions in photonic nanowires, and generation of non-classical states of light.
