Adam Brown

is a theoretical physicist at Stanford. He's interested in inflation, bubble nucleation and evolution, de Sitter space, quantum black holes, extra dimensions, the creation and wavefunction of the universe, bubbles of nothing, and all things cosmological.

Matthew Dodelson

is a graduate student at Stanford, working with Eva Silverstein. Currently interested in engineering holographic duals of inflation, as well as determining the fate of the massless scalar in de Sitter space. He would also like to better understand entanglement entropy in the context of quantum field theory and string theory.

Steve Giddings


is a faculty member in the UCSB Physics Department. He is interested in various aspects of quantum gravity, particularly black holes and inflationary cosmology, and in the phenomenology of the electroweak scale and beyond. His recent work on cosmology has includes study of infrared effects and problems, the problem of gauge-invariant observables, as well as signatures of tensor-mode fluctuations. Currently, much of his work is on the question of the unitarization of high-energy gravitational scattering (the black hole information problem).

Bart Horn

Is a postdoc at the Institute for Strings, Cosmology, and Astroparticle Physics (ISCAP) at Columbia University. Currently playing around with effective field theory methods for systematizing studies of large scale structure; other projects have included uplifting AdS/CFT to de Sitter and to FRW solutions, effects of heavy fields and particle production on inflation, and oscillating cosmologies and singularity theorems.

Andrew Jaffe

is an astrophysicist and cosmologist at Imperial College. He is a member of the Planck collaboration and manages to spend much of his time thinking about beams and pointing for the HFI instrument, although he also worries about the global topology of the Universe (or at least of our FRW patch) and other smaller-scale implications of CMB data (specifically Planck). He has been thinking about the best ways to interpret cosmological data for a couple of decades and is a founding member of the Imperial Centre for Inference in Cosmology. But he still wants to think of himself as a theorist.

Eiichiro Komatsu

has moved from the University of Texas at Austin to Max-Planck-Institut für Astrophysik (MPA) in August 2012 as a director of the new "Physical Cosmology" division at MPA. Over the last decade he has been working extensively on the analysis and interpretation of the cosmic microwave background (CMB) temperature and polarization maps obtained by the WMAP satellite. The primary focus of his research at MPA is to seek answers for three questions: (1) Has inflation happened? If so, how? (2) What is the nature of dark energy? (3) What is the nature of dark matter? His group tries to figure out how to use the CMB and the large-scale structure of the universe (or whatever else is needed) to answer these questions. While he enjoys working on the new Planck data (and is doing it a lot while staying at KITP), a new galaxy survey project called "Hobby-Eberly Telescope Dark Energy Experiment (HETDEX)," which is the first, blind, spectroscopic survey of emission-line galaxies, will keep him busy over the next five years from now. This survey is expected to detect the effect of dark energy on the expansion rate of the universe directly at z~2, even if it is a cosmological constant, and is also expected to significantly improve the limit on the sum of neutrino masses (if not detected). After that, he hopes to detect a signature of primordial gravitational waves from inflation in CMB polarization using a Japan-led CMB satellite called LiteBIRD, which should reach the tensor-to-scalar ratio of 0.001. Ah, and, of course, pretty sad to see that primordial non-Gaussianity was not found by Planck (look what he was hoping for....). Time to move on!

Andrew Liddle

is a theoretical cosmologist working at the Institute for Astronomy at the University of Edinburgh. He is interested in constraining cosmological models, particularly the nature of primordial perturbations and models of dark energy, and in developing new statistical methods for data analysis challenges. He is a member of the Planck Satellite collaboration (working mainly on SZ clusters) and the Dark Energy Survey.

Hiranya Peiris

is an astrophysicist working at the Dept of Physics and Astronomy at University College London. She is interested in theoretical and observational cosmology, cosmic microwave background, large scale structure, early universe theoretical physics, stellar dynamics, galaxy evolution, statistical methods, and optimal numerical algorithms. She is the coordinator of the CosmicDawn project, and a member of the Planck HFI Core Team and the Dark Energy Survey collaboration.

Edgar Shaghoulian

is a graduate student at the Stanford Institute for Theoretical Physics. He is interested in string theory and holography in and beyond AdS/CFT, especially as applied to de Sitter and FRW cosmologies. Having run out of more canonical things to try, he is currently trying to understand complexity theory/ultrametricity/glassy physics and its relation to cosmology and multicentered black holes. Mapping out observational signatures on the CMB of a a landscape populated by Coleman-de Luccia tunneling is also a UV passion. Finally, you can always engage him by talking about entanglement entropy, holographic or otherwise.

Eva Silverstein

is a member of the Department of Physics at Stanford and SLAC, interested in inflationary cosmology, from phenomenology and QFT to string theory and the interface between observations, UV sensitive quantities such as the tensor to scalar ratio, and the structure of string compactifications. Current obsessions also include developing a concrete `holographic' (AdS/CFT-like) framework for cosmology, deriving systematically the RG structure of spacetime dependent quantum field theory in various contexts, and black hole dynamics.
