Joseph Ghilarducci O’Rourke

Joseph Ghilarducci O’Rourke is an Assistant Professor at Arizona State University’s School of Earth and Space Exploration since 2020. He holds a PhD in Planetary Science from Caltech (2017) and a BS in Geology & Geophysics and Astronomy & Physics from Yale University (2012). His research focuses on planetary dynamics, particularly how internal processes like magma oceans, core evolution, and radiogenic heating shape surface conditions on worlds like Venus, Mars, Europa, and exoplanets. He uses numerical simulations and collaborates on mission proposals for planetary exploration. His work addresses topics such as Venusian volcanism, magnetic dynamo sustainment in super-Earths, and the habitability of ocean worlds like Ceres. He teaches courses in planetary science and geodynamics, including SES 421 Foundations of Planetary Science and graduate research seminars.

Dr. O’Rourke’s research themes include: planetary interiors and surface interactions, exoplanet dynamics, and mission proposal development for Venus and asteroid exploration (e.g., NASA’s Psyche mission). His work bridges fundamental theory with applied space science, emphasizing interdisciplinary approaches.

Key research trends in his articles (2022–2025) include Venus geodynamics, exoplanet magnetic fields, and the evolution of metallic cores in icy satellites. His recent studies on Venus emphasize resurfacing mechanisms, airburst scars, and CO2 sources in the atmosphere. He also explores the potential for life in Venus’ clouds and the origins of magnetization in asteroids like Psyche.

His grants and collaborations involve NASA-funded projects on planetary magnetic dynamos and Venus exploration. He advises students on planetary geology and mission design topics. No specific awards are listed, but his active publication record reflects his contributions to planetary science.
