I have broad interests in the processes that drive the evolution and behaviour of planetary bodies of all kinds and what gives rise to all the diversity we see across our solar system and beyond. My research primarily involves geodynamical modelling, with constraints coming in large part from spacecraft-based observations, especially relating to gravitational and magnetic fields. I work on problems related to magnetism, gravity, topography, elasticity/flexure/fracturing, heat production/transfer, and fluid dynamics. Some of my main research areas include: the interiors of icy moons; the magnetic evolution of rocky bodies like the Moon, Mars, and Venus; and space weathering (click below for more information on each of these research areas).

Postdoc Opportunity

I’m looking to hire an outstanding postdoctoral scholar with interests in planetary geophysics, including icy ocean worlds, planetary magnetism, and/or any similar/adjacent disciplines. The position would be based in Austin, Texas. Anyone with strong quantitative/programming skills, enthusiasm for the research, and an interest in a mutually beneficial collaborative working environment, should feel free to get in touch (douglas [dot] hemingway [at] utexas [dot] edu).

About Me

I have a long-standing interest in space exploration and have enjoyed careers both in the space industry and in planetary science research. I spent roughly ten years as a space industry professional, first specializing in on-orbit robotic servicing for the International Space Station and the Hubble Space Telescope and then later serving as Chief Scientist for the Civil Space Business Development team at Maxar Technologies, helping to connect space science/exploration mission goals with Maxar's technical solutions in spacecraft, spacecraft subsystems, and robotics.

I completed my PhD in the Department of Earth and Planetary Sciences at the University of California Santa Cruz. My PhD advisors were Ian Garrick-Bethell and Francis Nimmo. My dissertation committee also included Gary Glatzmaier and Jasper Halekas. I then held postdoctoral fellowships at the Miller Institute for Basic Research in Science at the University of California Berkeley, where I was hosted in the Department of Earth and Planetary Science by Michael Manga and at the Carnegie Institution for Science's Department of Terrestrial Magnetism (now Earth and Planets Laboratory) in Washington, DC, where I was hosted by Peter Driscoll. I am now an Assistant Research Professor at the University of Texas Institute for Geophysics, part of the Jackson School of Geosciences at the University of Texas at Austin.
