In the field of cosmology, we measure distant objects to examine the large scale universe. We learn about its structure, content, origin, and evolution.

In our group, our primary subject is the Cosmic Microwave Background. This is the afterglow of the Big Bang, seen today from deep space in the microwave-wavelength band of the electromagnetic radiation spectrum. We also work on topics like large-scale structure, the cosmic X-ray background, and gravitational weak lensing.

As researchers who specialize in data analysis, we support observational projects that provide a steady flow of data for us to interpret. We help to plan for the next generation of scientific instruments so that this flow continues.

Today, experimental designs are so ambitious that they require multinational collaborations to field the instruments and dedicated analysis teams to process the data. We now belong to three large, currently-active collaborations:

In the past, we worked with the Planck satellite mission and the Q/U Imaging ExperimenT (QUIET). We have worked on a number of independent projects in smaller groups, some related to the CMB and some related to other aspects of cosmology or astrophysics.
