Meenakshi Wadhwa
Director

Meenakshi Wadhwa is the Director of the School of Earth and Space Exploration.

Her research focuses on isotope cosmochemistry, in particular the sources and distributions of extinct radionuclides in the solar nebula; the formation and evolution of crust-mantle reservoirs on Earth, Moon and Mars; and the abundance and origin of water and other volatiles on rocky bodies in the solar system.

Ramon Arrowsmith

Ramon Arrowsmith
Associate Director of Operations

Ramon Arrowsmith studies active faulting, earthquake geology, tectonic geomorphology, and the geologic framework for human origins. Dr. Arrowsmith teaches Field Geology, Structural Geology, Geomorphology, and Computers in Earth and Space Exploration.

Hilairy Hartnett

Hilairy Hartnett
Associate Director of Graduate Initiatives

Hilairy Hartnett has joint appointments in the School of Earth and Space Exploration and in the School of Molecular Sciences. Her current research interests are in the areas of biogeochemistry and organic geochemistry and focus on how geochemical, microbial, and anthropogenic processes affect the dynamic linked elemental cycles in modern, and paleo-environments.

Chris Groppi

Chris Groppi
Associate Director of Undergraduate Initiatives

Christopher Groppi is an experimental astrophysicist interested in the process of star and planet formation and the evolution and structure of the interstellar medium. His current research focuses on the design and construction of state of the art terahertz receiver systems optimized to detect the light emitted by molecules and atoms in molecular clouds, the birthplace of stars.

Patrick Young

Patrick Young
Associate Director of Community Outreach

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. His current research touches on computational hydrodynamics simulations of stellar interiors, supernovae and gamma-ray bursts and the synthesis and ejection of elements by nuclear fusion in stars and stellar explosions. He also models the evolution of stars and how their radiation, winds, and stellar activity may affect the habitability of nearby planets.

Christy Till

Christy Till
Associate Director for an Inclusive Community

Christy Till is a geologist who teaches classes and leads a multidisciplinary research program on the role of magma in the formation and evolution of planets, known as the E.P.I.C. lab. E.P.I.C. lab research includes determining the timescales and triggers for eruptions at active volcanoes in the US, growing minerals and magma in high pressure and temperature laboratory experiments, and studying the likely compositions of magma and crusts on exoplanets. Dr. Till also has deep interests in working for justice, equity, diversity, and inclusion in academic science and improving science communication.
