ASU Nexus for Exoplanet System Science

NExSS Videos

Steve Desch

Steve Desch is a theoretical astrophysicist who models the formation of solar systems and planetary processes. His modeling draws on his expertise in magnetohydrodynamics, radiative transfer, dust microphysics, meteoritics, and other astrophysics, as well as numerical computing.

Ariel Anbar

Ariel Anbar is a biogeochemist interested in the past and future evolution of the Earth as a habitable planet and how this knowledge informs the search for inhabited worlds beyond Earth. His current research focuses on the chemical evolution of the environment, especially changes in ocean oxygenation through time, and its consequences for life.

Sara Walker

Sara Walker is a physicist and astrobiologist interested in the physical nature of life and its origins. Her research primarily focuses on the emergence of life, combining techniques from theoretical physics, chemistry, and information science to uncover how the first living systems may have arisen on a lifeless planet.

Everett Shock

Everett Shock and members of his research group build algorithms to estimate thermodynamic data; analyze water, sediment, rock and biological samples; integrate analytical and thermodynamic data in models of geochemical and microbial processes; and testing ideas about the biogeochemical process of subsurface biosphere, and the potential for life on other planets.

Patrick Young

Patrick Young is a theoretical astrophysicist interested in the lives and deaths of stars and their effects on their environments, from synthesis of the chemical elements to planetary habitability. He works with geoscientists to understand how their unexpected diversity may affect the mineral makeup and geophysical evolution of exoplanets.

Meenakshi Wadhwa is a cosmochemist interested in deciphering the origin and evolution of the Solar System and planetary bodies through geochemical and isotopic means. She uses high-precision mass spectrometric techniques to investigate a wide range of Solar System materials.

Natalie Hinkel

Natalie Hinkel studies the element abundances in the solar neighborhood, or within 150pc of the Sun. She has put together the largest collection of stellar abundances, called the Hypatia Catalog, for 50 elements within +3,000 main sequence (FGK-type) stars as compiled from literature.

Denton Ebel

Denton Ebel is a geologist specializing in meteorites: pieces of planets and “left-overs” from the formation of the solar system. The distant, resource-rich asteroid belt is his field area. He develops thermodynamic models describing the outcomes of condensation, evaporation, and crystallization processes.

Maggie Turnbull

Dr. Turnbull is an astrobiologist whose expertise is in identifying planetary systems that are capable of supporting life as we know it. She developed a Catalog of Habitable Stellar Systems for use in the search for extraterrestrial intelligence (SETI) and she has studied the spectrum of the Earth to identify telltale signatures of life. This information will be used to inform the New Worlds team as the mission develops from concept to reality.

Stephen Kane

Stephen Kane is an Assistant Professor in the Physics & Astronomy Department at San Francisco State University. His primary research interest is detecting and characterizing planets outside our solar system.

Michael Pagano

Michael Pagano is a postdoctoral research fellow at Arizona State University’s School of Earth and Space Exploration.
