Earth as an Exoplanet for the Era of Exo-Earths

Advisor: Tyler Robinson

PTYS Graduate Student Maizey Benner

Maizey’s paper entitled Microstructural analysis of phosphorus (P)-bearing assemblages in type 3 chondrites: Implications for P condensation and processing in the early solar nebula is one of the two papers selected for this award. 

Her paper addresses the chemical behavior of phosphorous in chondritic meteorites and in samples returned by the Hayabusa2 mission. She has been using a combination of electron- and ion-beam techniques in the Kuiper-Arizona Laboratory for Astromaterials Analysis (K-ALFAA) to study P-bearing materials in petrologic type-1 through type-3 carbonaceous and ordinary chondrites, and thermodynamic modeling and density functional theory to better understand the materials formation conditions.

Anna Taylor PTYS Graduate Student

The fellowship is awarded annually to up to 30 women in doctoral programs in aerospace engineering and space sciences.

Anna’s research examines how hydrogen and helium escape from hot Jupiter-sized exoplanets under intense stellar radiation, using hydrodynamic simulations, stellar flux models, and spectroscopic observations to explore planetary evolution and star–planet interaction.

PTYS Graduate Student Namya Baijal

The Planetary Science Institute has selected University of Arizona graduate student Namya Baijal as one of two recipients of the 2025 of the 2025 Pierazzo International Student Travel Award

PSI established the award in memory of Senior Scientist Betty Pierazzo to support and encourage graduate students to build international collaborations and relationships in planetary science. Each awardee will receive a certificate and check for $2,000 at their respective conferences. 

Baijal will attend the Europlanet Science Congress – Division of Planetary Sciences Joint Meeting 2025 to be held in Helsinki, Finland from Sept. 7-12 where she will present her research titled “Three-dimensional Modelling of the Major Impact Craters on (16) Psyche.” Through her research, she works to understand how collisions have shaped the surface of asteroid (16) Psyche, a unique metal-rich asteroid in the main belt and the target of NASA’s Psyche Mission, set to arrive in 2029. Through impact modeling, she and her colleagues aim to help answer the mission’s central question: “Is Psyche the leftover core of a differentiated planetesimal, and if so, how did it form?” 

Pierazzo, after whom the prize is named, was an expert in the area of impact modeling throughout the solar system, as well as an expert on the astrobiological and environmental effects of impacts on Earth and Mars. In addition to her research, she was passionate about education, teaching and public outreach, developing planetary-related classroom materials, professional development workshops for teachers, and teaching college-level classes herself. Betty believed in the strength of broad collaborations in all of her research and education activities. 

This award memorializes the scope of how she lived her life and the good she sought to bring to our profession and communities.

A STEM Pathway


The UA/NASA Space Grant Program, in collaboration with the UA Graduate College and the nominating department, funds six graduate fellowships per year to exceptional graduate students interested in promoting the understanding of space-related research to the public. Applicants are asked to propose a 1-2 year project focused on educational outreach, knowledge transfer, technology transfer, science for society, and/or the promotion of science, technology, engineering and mathematics (STEM) to those traditionally underrepresented in STEM. In keeping with National Space Grant College and Fellowship Program goals, Space Grant Fellows develop projects that promote the understanding of space-related research to the public through original research and outreach efforts. Awards include a stipend, tuition and registration fee waivers, student health insurance, and a travel grant to attend professional conferences.

Madison Tuohy

Madison is a third-year Ph.D. student in Geosciences, completing a graduate minor in Planetary Sciences. She is advised by Associate Professor Christopher Hamilton. Madison is interested in the active eruptions in Fagradalsfjall, Iceland, and how these eruptions can be used for hazard mitigation and planetary analogs.

Madison recently won four awards from the Dept. of Geosciences:

  • Montgomery Associated Best Overall Talk: Observing the effects of complex topography on fissure-fed facies in the 2021-2023 Fagradalsfjall (Iceland) eruption series
  • Bert S. Butler Scholarship
  • Spencer R. Titley Graduate Scholarship
  • John and Nancy Sumner Scholarship which Madison will use to travel to Italy to participate in a workshop focused on observing active volcanism at Mt. Etna and Stromboli and then to Geneva, Switzerland, to present her work at the IAVCEI (International Association of Volcanology and Chemistry of the Earth's Interior) General Assembly.

Nathan Hadland

Nathan Hadland has been named an ARCS Scholar for the 2025-2026 academic year. The ARCS (Achievement Rewards for College Scientists) Foundation advances science and technology in the United States by providing financial awards to academically outstanding students who are U.S. citizens studying to complete degrees in science, engineering, math, technology, and medical research. Scholars receive a cash stipend, full tuition, and a travel grant.

Nathan’s research focuses on microbial life in volcanic environments as an analog for life on Mars. He is a fifth-year graduate student advised by Associate Professor Solange Duhamel (MCB) and Associate Professor Christopher Hamilton.

The Curson Education Plus Fund in Planetary Sciences and LPL was established by Shirley Curson, a generous donor and friend of LPL, for the purpose of supporting travel expenses outside the state of Arizona during summer break. The award is open to students in the Department of Planetary Sciences and Lunar and Planetary Laboratory who propose to fund study, museum visits, special exhibits, seminars, instruction, competitions, research and other endeavors that are beyond those provided by the normal campus environment and are not part of the student’s regular curriculum during the recipient’s school year.

To donate to the Curson Travel fund, visit the University of Arizona Foundation.

Studying the evolution of exoplanetary atmospheres and their interactions with their host stars, with a research focus on atmospheric escape, a crucial process that shapes planetary atmospheres over time, influencing their composition, structure, and potential habitability. The integration of theoretical hydrodynamic models with observational data aims to refine our understanding of how escaping atmospheres are detected through spectral features.


Chengyan XieChengyan Xie
