Kunihiko Nishiizumi

Senior Space Fellow

Interest in cosmochemistry and Nuclear chemistry. Research involved cosmic ray exposure histories of extraterrestrial materials (meteorites, lunar samples, and micrometeorites) and terrestrial materials (surface rocks and soils) using cosmic-ray produced (cosmogenic) nuclides such as 129I, 53Mn, 10Be, 26Al, 36Cl, and 41Ca; secular variation of solar and galactic cosmic rays.

Marit Oieroset

Full Research Physicist

Marit studies large-scale and microphysical properties of magnetic reconnection, an energy conversion process important in space and astrophysical contexts. In her research she has used spacecraft observations from Wind, Mars Global Surveyor, Lunar Prospector, Cluster, THEMIS, and Magnetospheric MultiScale (MMS). Read More…

Mitsuo Oka

Assistant Research Physicist

Mitsuo Oka has a broad interest in the kinetic properties of space plasma, including solar wind with interstellar-origin pickup ions, shocks, and magnetic reconnection. His recent primary focus has been on electron acceleration in solar flares and terrestrial plasma environment (including the bow shock and magnetotail). Read More…

Barry Welsh

Full Research Astronomer

My research interests are in high resolution spectroscopy of the local interstellar medium (ISM) and the
detection of exocomets. Recent publications include a 3-D map of the LISM to 300pc around the Sun,
and the discovery of over 20 new stellar systems that show evidence for the evaporation of gas from exocomets
as they fall towards a central star.
