Expertise: dust devils, dunees, earth, venus




Dr. Neakrase’s research has involved different aspects of the martian atmosphere, specifically the movement of sand and dust on the surface of Mars. His work has involved martian seasonal polar processes, dust devil dynamics on Earth and Mars, and other types of aeolian geomorphologic processes including dune formation and migration and wind streak mapping. Ph.D. work involved experiment design with the Arizona State University Vortex Generator, Arizona State University Planetary Wind Tunnel and Planetary Aeolian Laboratory (NASA Ames) Wind Tunnel. Current research interests are martian and terrestrial dust devils, venusian dunes, and planetary aeolian sediment transport.

Currently Dr. Neakrase works with interfacing with active mission and other derived data providers with the NASA Planetary Data System Atmosphere’s Node at NMSU, where he helps to design, review, ingest, and host via the web science data. He has been involved with the design and roll-out of the PDS’s latest archiving standard, PDS4. He is currently the chair of the PDS4 Change Control Board, where changes to the PDS4 system are vetted for implementation in the active system.
