Appearing all three days
Alexander Sehlke has been fascinated by rocks and minerals since his early childhood, in particular volcanoes and earthquakes, and space! So Alex decided to pursue his undergraduate degree in Geosciences in Hannover, Germany, and then earned his PhD in Geology at the University of Missouri in 2015, after which he started at NASA Ames Research Center. His studies involve planetary volcanism by conducting field work in volcanic terrains on Earth that appear similar to those found on the Moon, Mars and other rocky objects in our solar system. Sehlke also conducts many experiments in his laboratory, including melting rocks and measuring how fluid or viscous they are, as well as heating rocks returned from the lunar surface and asteroids to see how much light they emit during heating as method to reconstruct their thermal and radiation history.
