Dr. Alexander Selhke

NASA Ames Research Center
Postdoctoral Research Fellow
Volcanoes have fascinated Alexander Sehlke since his childhood. He started studying Geosciences at the Leibniz University of Hannover, Germany in 2005. In 2011, Alexander began his doctoral studies at the Department of Geological Sciences at the University of Missouri – Columbia, and received his PhD in 2015. He studied the rheological evolution of terrestrial and planetary basalts during cooling and crystallization, experimentally. His studies on lava flow emplacement and the mechanism of the development of diverse lava surface morphologies were complemented by field investigations on both active and inactive lava flows erupted on the Big Island of Hawaii, Guatemala and Costa Rica. Field work included sample collection and measurements of the geometry of channelized sections within lava flows and different type of surface morphologies (e.g., pahoehoe, transitional, `a`a). Alexander has taught undergraduate students in the field and the classroom as a teaching assistant in Mineralogy and as a course instructor during his time at the University of Missouri. Alexander is currently a NASA post-doctoral fellow at NASA Ames Research Center, located in the heart of Silicon Valley. He continues to study volcanic landforms, focusing on the Moon, Near Earth Asteroids (NEA’s) and the surface of Mars and its moons, as part of NASA’s FINESSE (Field INvestigation to Enable Solar System Sciences). He is also working with NASA’s BASALT (Biologic Analog Science Associated with Lava Terrains) project to evaluate handheld science instruments and how they can be incorporated into future human exploration missions of our solar system.
