  • Brief Bio

    Dr. Wollack’s research concentrates on the development and use of precision imaging systems for astrophysics and cosmology. He has contributed to the design, fabrication, and characterization of far-IR sensors, waveguides, optics, and other components for ground, balloon, and space-based radiometric applications.

    RESEARCH:
    Cosmic Microwave Background: spectrum, anisotropy, polarization, dark energy
    Astrophysical Observations: large scale galactic emission, mapping techniques
    Instrumentation: optics, sensors radiometry and precision flux calibration

    EDUCATION:
    Ph.D. Physics (1994), Princeton
    B.S. Physics (1987), University of Minnesota, Institute of Technology
