Brief Bio
- Astrophysics and cosmology are Ed Wollack's primary research interests. His work concentrates on the characterization of diffuse astrophysical backgrounds and understanding their implications for structures on the largest scales in our universe. In carrying out these efforts he has contributed to the design of a variety of sensors, guided wave, and optical components for ground, balloon, and space-borne applications.
