Christopher Edwards

ÇàÇà²ÝÊÓƵ Professor; Director NAU/NASA Space Grant
Dr. Edwards is a planetary geologist and instrument developer. His research focuses on constraining early solar system processes by using the composition, physical properties and processes, and morphology of planetary surfaces. He is a participating scientist on the Mars Science Laboratory Curiosity Rover, and has works actively with numerous other NASA Mars missions including the 2001 Mars Odyssey Thermal Emission Imaging System, Mars Global Surveyor Thermal Emission Spectrometer, and the Mars Reconnaissance Orbiter Compact Reconnaissance Imaging Spectrometer for Mars.

Joshua Emery

Professor
Dr. Emery applies the techniques of astronomical reflection and emission spectroscopy and spectrophotometry of primitive and icy bodies in the near- (0.8 to 5.0 microns) and mid-infrared (5 to 50 microns) to investigate the formation and evolution of the Solar System and the distribution of organic material. The Jupiter Trojan asteroids have been a strong focus of his research, and he also regularly observes Kuiper Belt objects, icy satellites, and other asteroid groups to understand the state of their surfaces as related to these topics. Along with telescopic observations, he contributes to Solar System exploration as a science team member on the OSIRIS-REx asteroid sample return mission, the Lucy Trojan asteroid flyby mission, and the NEO Surveyor Mission infrared telescope mission.

I work on theoretical and computational astrophysics with a focus on planet formation, planet dynamics and astrophysical fluid dynamics. I use super-computer simulations and pencil-and-paper calculations to study how planets, stars or blackholes evolve over short and long time-scales as they interact with surrounding gas to explain their observed orbital properties.

Assistant Research Professor
Alicia earned her BS in Aerospace Engineering and her MS in Forestry from Texas A&M University in 2004 and 2006. She earned her PhD in Geological Sciences from Arizona State University in 2015. Alicia’s research integrates remote sensing, field work, and laboratory measurements to better understand planetary surface processes and the role of climate in alteration processes. She is especially interested in using geochemistry and mineralogy to investigate cryosphere-bedrock interactions on Earth and Mars. Her work in the Department of Astronomy and Planetary Science focuses on investigating the composition and origin of weathering products at Mars analog field sites such as the Cascades Range, Oregon, USA, and the summit glaciers of Mt. Kilimanjaro, Tanzania. Alicia is a team member on the Thermal Emission Imaging System (THEMIS) aboard NASA’s Mars Odyssey.

Jean-Francois Smekens

Assistant Research Professor
I apply spectroscopic and imaging remote sensing techniques to the detection and quantification of volcanic emissions (gases, aerosols, ash, etc.) and surfaces. My research aims to link observable surface signals (from ground-based instrument, UAS platforms or satellites) to the dynamics of eruptive processes, so that we may learn to forecast them and mitigate the risks associated with volcanic eruptions.

I am also interested in the detection and characterization of plumes from wildfires.

Michael Gowanlock

Mike Gowanlock obtained his PhD in Computer Science from the University of Hawaii at Manoa in 2015, and was a postdoctoral associate at MIT Haystack Observatory from 2015-2017. Mike is an associate professor in the School of Informatics, Computing, and Cyber Systems at NAU where he works on research in parallel and high performance computing across numerous application areas. His work with the Department of Astronomy & Planetary Science is focused on designing new parallel algorithms to support large-scale surveys, such as the Zwicky Transient Facility (ZTF) and the Rubin Observatory (RO), where high throughput computational approaches are needed to maximize the scientific return of these surveys. Currently, he is working on the Solar System Notification Alert Processing System, which is a ZTF and RO alert broker.
