People & Publications
Dr. Raut is an experimental physicist and planetary scientist whose research addresses fundamental questions that emerge following detection of molecules in extraterrestrial environments by observational efforts. Within CLASSE, Dr. Raut creates laboratory-scale replicas of the extraterrestrial environments and conducts experiments with cosmic analogs (ices, minerals) to elucidate the nature, origin, and evolution of icy surfaces ubiquitous in the outer Solar System and beyond.
Dr. Retherford is a planetary scientist specializing in the use of space-based UV observations to study planetary atmospheres and surfaces. His research interests include the aurorae and airglow of the Galilean satellites, Jupiter, the Moon, Mars, and Pluto.
Dr. Teolis is a physicist, experimentalist and planetary scientist whose expertise include the formation and evolution of planetary atmospheres and magnetospheres, and the chemical and radiation processing of the surfaces of icy bodies in the outer solar system.
Senior Research Scientist
Dr. Poston is a planetary surface chemist. His areas of focus include 1) surface properties and habitability of Ocean Worlds; 2) present-day solar system volatiles, thermal and non-thermal processes, surface-bound exospheres, and atmospheric processes; 3) In Situ Resource Utilization (ISRU) and power generation; and 4) flight instrumentation and mission formulation.
Dr. Kammer is a planetary scientist specializing in the study of tenuous atmospheres and the retrieval of atmospheric composition using solar and stellar occultation observations in the far- and extreme-ultraviolet. His research interests also include hydrocarbon photochemistry and its effects on the evolution of planetary atmospheres/surfaces of all sizes, from smaller bodies such as Titan, Pluto, and Charon, to the largest planets such as Jupiter and Saturn.
At CLASSE, Josh contributes to Charon project investigating the origin of its red polar albedo. He has led the comparative analyses of photoproduct distribution emerging from Lab experiments and Exosphere model against New Horizons images, especially from MVIC and LORRI. Josh recently secured another New Frontiers Data Analysis Program (NFDAP) funding to continue this exciting research!
Dr. Protopapa’s research focuses on the compositional characterization of small bodies in the outer solar system (comets, trans-Neptunian objects), as well as the Moon. Her work folds together infrared spectral-imaging observations from spacecraft (New Horizons, Rosetta, Deep Impact) and ground-based instruments (VLT, Keck, and IRTF), laboratory measurements and theoretical radiative transfer models. Dr. Protopapa has an active involvement in several mission teams. She is Co-I on the ESA Comet Interceptor Mission and the NASA New Horizons Mission.
Within CLASSE, Dr. Protopapa analyzes and model LAMP phase curves across the surface of the Moon and work in photometric modeling of laboratory phase curves of Apollo soils in dry and water-infused states. She also contributes to NFDAP projects investigating the origin of Charon’s red polar albedo.
Dr. Qasim experimentally investigates ice and mineral-ice chemistry that occurs from interstellar clouds to the small bodies of our solar system. She is also involved in astrobiology and astronomical observations of interstellar molecules. Within CLASSE, she will lead experimental work expanding into ice chemistry on planetary surfaces such as the radiolysis and sputtering of Europan salty ices, relevant to the Clipper mission.
Dr. Stevanovic is a director of the Kleberg Advanced Microscopy Center, a shared-core user facility at the University of Texas at San Antonio (UTSA). Her expertise involves in-situ TEM/SEM characterization of materials under externally applied stimuli: heat, gas, and liquid. Her research focuses on bridging the "pressure gap" in electron microscopy: from high-vacuum to dynamic in-situ imaging of real-time structural and chemical changes in materials.
Within CLASSE, Dr. Stevanovic collaborates on nanoscale imaging and chemical characterization of planetary analogs and extraterrestrial samples by employing Focused Ion Beam, aberration-corrected Transmission Electron Microscopy, Raman Microscopy, and X-Ray Diffraction.
Bereket Mamo is a graduate student in the joint UTSA-SwRI Space Physics program. His research focuses on understanding far ultraviolet reflectance of the surface of Europa and the Moon leveraging laboratory experiments, observations and modeling.
Caleb Gimar is currently a graduate student in the joint UTSA-SwRI Space Physics program. His research contributions within CLASSE focus on far-ultraviolet reflectance studies of lunar simulants and soils and the optical properties of radiation-processed methane relevant to Charon.
