Visitors Program

We maintain an active program for visiting scholars. BCCP hosts visitors at all levels, from senior scientists to postdocs, graduate students, and undergraduates. If you would like to visit BCCP, please fill out the form here.

Longer term visits involving collaborative activities with BCCP members are especially encouraged. BCCP can provide financial support for longer term visitors working with BCCP members on BCCP related projects. The applications are reviewed by a committee several times a year. All decisions are based on the availability of space and funding.

BCCP Lunches

BCCP Lunch Events usually take place in Hearst Field Annex  (HFA) B-1 at noon. The venue and dates may be subject to change. To keep you notified, please contact Melissa Barclay ( to be added to the lunch mailing list.


Oliver Zahn


Zahn originally came to Berkeley as inaugural BCCP Fellow after undergraduate work at Max-Planck-Insitute for Astrophysics and NYU, as well as doctoral work at Harvard and Heidelberg.

He recently became the executive director of BCCP and as such oversees the centers’ cosmology program as well as its new interdisciplinary data science initiative. Zahn is a multipurpose cosmologist, advancing the understanding of the origin and evolution of structure in the Universe by applying a variety of statistical methods to complementary astrophysical observables. He connects data to theory through cutting edge numerical simulations of cosmological structure formation.

 Zahn frequently analyses terabyte surveys of the Cosmic Microwave Background, Galaxies, and Galaxy clusters for to generate insights into the workings of the cosmos. He has also been involved in studies exploring the redshifted 21 cm line as a new cosmological probe, and his research has acted as a driver for pushing a new generation of radio telescopes that might revolutionize studies of reionization, inflation, and dark energy/gravity theory.  By maintaining a data driven  approach,  Zahn has achieved several “firsts” and other important findings together with his working groups.
