Dr. Christopher Hamilton has been promoted to Associate Professor with tenure. Dr. Hamilton's research focuses on geological surface processes to better understand the evolution of the Earth and other planetary bodies. His specialty relates to volcanology and specifically to lava flows, magma-water interactions, and explosive eruptions using a combination of field observations, remote sensing, geospatial analysis, machine learning, and geophysical modeling.

Dr. Walter Harris has been promoted to Full Professor. Dr. Harris' research is focused on the structure of thin atmospheres and their transition to and interactions with the space environment. He is particularly interested in the information that comet atmospheres provide about basic photochemical processes, the formation of the solar system, and the characteristics of the solar wind. He is also engaged in an ongoing study of the plasma interface between the solar wind and interstellar medium via remote sensing of interstellar neutral material as it passes through the solar system.
