Graduate Fellowship Program

The Carnegie Graduate Fellowship program is now open to third-year and beyond students at Chilean Universities. A list of Carnegie staff members who plan to participate as advisors is below, along with brief summaries of their current research. Students who are interested in the fellowship should contact potential advisors to discuss possible research projects in more detail. Applications are open every year and are typically received between early March and May 31st. Please visit to check for the latest open call.

Andrew Benson

Benson is a theorist focusing on modeling the formation and evolution of galaxies. His interests include: cosmology, data-driven models of galaxy formation, semi-analytic modeling, cold dark matter and alternative dark matter models, measuring the distribution of dark matter via gravitational lensing, the galaxy mass function, and dwarf galaxies.

Guillermo Blanc

Blanc is an observer focused on trying to understand the physical processes by which galaxies form and evolve throughout the history of the Universe. He uses a multi-wavelength approach spanning from the UV to the radio to study both galaxies in the local "present day" universe as well as at high redshift, where we can directly observe the early epochs of galaxy evolution. His interests include: the properties of young galaxies at high redshift, the large scale structure of the Universe, the process of star formation on galactic scales, and the measurement of chemical abundances in galaxies.

Dan Kelson

Kelson is an observer studying galaxy formation and evolution at intermediate redshift. His interests include: galaxy clusters, galaxy groups and the impact of environment on galaxy properties, star formation rates, stellar masses and the initial mass function, large spectroscopic surveys, lensing, and optimal data reduction techniques.

Juna Kollmeier

Kollmeier is an observationally-oriented theorist whose work ranges from the formation of the Milky Way to the intergalactic medium at high redshift. Her interests include: hydrodynamic simulations of intergalactic gas, the Ly-alpha forest, ultraviolet background radiation, galactic winds, black hole masses, accretion on active galactic nuclei, hypervelocity stars, RR Lyrae variables as tracers of galactic structure, the distance ladder, and precision stellar astrophysics.

Barry Madore

Madore is a philosophically-inclined observational astrophysicist. One of his current interests centers on "new physics" (specifically, additional neutrino-like species) which is implied by the "tension" between the local value of the expansion rate of the Universe and the Hubble constant inferred from modeling Planck observations of the Cosmic Microwave Background. He also has a long-standing interest in understanding the physics underlying the rate of star formation in galaxies and over cosmic time.

Andrew McWilliam

McWilliam is an observer who specializes in analyzing the chemical abundances of stars. His interests include: metal-poor stars, the chemical evolution of the Milky Way and other nearby galaxies, chemical abundances of dwarf galaxies and globular clusters, supernova yields, the synthesis of heavy elements, the structure and history of the Milky Way's bulge, and the measurement of abundances from integrated light spectroscopy.

Nidia Morrell

Morrell is an observer who studies massive stars and supernovae. Her interests include the fundamental properties of massive stars, massive binaries, stars in young clusters and associations in the Galaxy and the Magellanic Clouds, and the Carnegie Supernova Project.

John Mulchaey

Mulchaey is an X-ray and optical observer who studies galaxy groups and the gas within them. His interests include: the missing baryons, the warm-hot intergalactic medium, spectroscopic galaxy surveys, the connection between galaxies and absorbing gas, the evolution of galaxy groups with redshift, and the effect of group environments on galaxy properties.

David Osip

Osip is an observer studying solar system bodies and exoplanets. His interests can be summarized as "chasing shadows", including stellar occultation observations of small bodies in our solar system, transit photometry and spectroscopy of extrasolar planets, and physical characterization of asteroids, comets, centaurs and trans-Neptunian objects with a prioritization towards spacecraft mission targets.

Michael Rauch

Rauch is an observer probing the galaxies and the intergalactic medium at high redshift. His interests include: the large scale distribution of baryons in the universe, galaxy formation, the cosmic web, the interactions between galaxies and the IGM, Ly-alpha emitters, the escape of UV radiation from galaxies, galactic outflows, gas accretion and its observable consequences, and the enrichment and ionization history of the IGM.

Gwen Rudie

Rudie is an observer whose primary focus is high-redshift galaxies and their surrounding circumgalactic gas. Her interests include the detailed physical and chemical properties of the circumgalactic medium (CGM) and intergalactic medium (IGM), the physical properties of high-redshift galaxies including metallicities, star-formation rates, and outflows, the chemical evolution of galaxies and its impact on the chemistry of the CGM, metallicity indicators in high-z galaxies, and the IGM as a tool for understanding galaxy evolution and optical and NIR spectroscopy.

Josh Simon

Simon is an observer studying nearby galaxies. His interests include: the distribution of dark matter in galaxies, the dark matter content of dwarf galaxies, searching for new dwarf galaxies, the origin and properties of the most metal-poor stars, the chemical evolution of galaxies in the early universe and today, the initial mass function, the star formation histories of the smallest galaxies, and the progenitors of supernova explosions.
