Dr. Hurtado's research expertise is in field geology; remote sensing (including Unmanned Aerial Systems); and terrestrial/planetary tectonics and geomorphology. He applies this expertise in two broad research areas: lunar geology and active tectonics in the Bhutan Himalaya. Dr. Hurtado's lunar geology work has focused on the use of remotely-sensed datasets to investigate the potential resources on the Moon and their geologic context. This has included using thermal infrared data to discover and characterize caves in the lunar subsurface, hyperspectral data to map the presence of water and titanium, and topographic data to identify water-related volcanic features. He has also conducted work at planetary analog sites to show how shallow geophysical tools (e.g., gravity, magnetics, GPR) can be used to characterize water-related explosive volcanic features on other planets as well as how other field deployable instrumentation can be used for planetary surface exploration. His Bhutan work has focused on field studies of Quaternary geomorphologic features (river terraces, fault scarps, etc.) that record ongoing tectonic uplift in the Himalaya. The objective of this work is to evaluate models for the evolution of the Bhutan Himalaya and assess seismic hazards. In addition to these research areas, Dr. Hurtado also has expertise in human space exploration through ongoing collaborations with NASA in mission simulation activities and astronaut crew training. Dr. Hurtado has also worked on various commercial spaceflight projects, including passenger training program and vehicle development with Virgin Galactic.
