Research Interests: Organic molecules are found in a diverse set of astronomical environments, demonstrating that there are efficient astrochemical pathways to molecular complexity. Interstellar grains and their icy mantles are proposed to be important formation sites of many of these molecules. Understanding the structure, dynamics and chemistry of ices is thus key to advance our understanding of the chemistry in space.
Research Interests: Cosmology and extragalactic astronomy with a mix of theoretical and observational methods; the development of the baryon acoustic oscillation method to measure the cosmic distance scale and study dark energy.
Research Interests: Radio and radar techniques: applications to astrometry, astrophysics, geophysics, planetary physics, and tests of theories of gravitation; Pre-college and college science education: curriculum development and teacher training.
Research Interests: Her research focuses on the catastrophic death of stars, “supernovae”. She combines astronomical data sets from many observatories and satellites in order to probe the eruptive, destructive, and explosive nature of supernovae and their role in the Universe.

Research Interests: Professor Sasselov studies, among other things, extrasolar planets, and he's a co-investigator on NASA's Kepler mission, which is monitoring 100,000 stars in a three-year hunt for exoplanets -- including Jupiter-sized giants. Sasselov watches for exoplanets by looking for transits, the act of a planet passing across the face of its star, dimming its light and changing its chemical signature. This simple, elegant way of searching has led to a bounty of newly discovered planets.
Research Interests: Multi-wavelength (primarily X-ray) spectroscopic studies of energetic accretion systems (X-ray binaries, AGN). Interstellar dust studies (composition and distribution) through laboratory experiments and space-based observations.
Research Interests: His cosmology research focuses on observations of the cosmic microwave background (CMB) to reveal signatures of the physics that drove the birth of the universe, the creation of its structure, and its present-day expansion. His research over the past two decades has involved the design, deployment, and operation of multiple generations of radio telescopes at the Amundsen-Scott Station at the South Pole.
Research Interests: Theoretical studies of dynamical processes in cosmology and galaxy formation/galaxy evolution. Numerical simulations of stellar dynamical and hydrodynamical systems. Investigations of the physics of compact objects, particularly neutron stars and the interplay between thermal and magnetic processes in strongly magnetized neutron stars.
