In the field of cosmology, we use measurements of the universe to examine the structure and contents of the large scale universe, and its origin, evolution, and fate.

In our group, our primary subject is the Cosmic Microwave Background, the radiation afterglow of the Big Bang, and 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 such large, currently-active collaborations: the Atacama Cosmology Telescope (ACT) is currently taking data; the Simons Observatory is under construction and expected to take its first measurements in 2021; and the CMB-S4 project is in the planning and proposal phase and will take its first measurements around 2027.

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.
