Columbia University invites applications for a full-time Associate Research Scientist in the Columbia Astrophysics Laboratory, to perform laboratory simulations of solar wind ion irradiation of Mercury’s regolith surface. The primary responsibility will be to carry out laboratory experiments to improve in-situ and remote-sensing data of Mercury. The successful candidate will join the group headed by Senior Research Scientist Dr. Daniel Wolf Savin; they will participate in designing, building, and performing experiments utilizing a novel ultrahigh-vacuum ion-beam apparatus to study the spectral changes and sputtering yields of regolith-like loose powders. In addition, the successful candidate will be expected to collect, analyze, and interpret data; generate and modify computer analytic and instrumentation control code; participate in group and collaboration meetings; write papers and reports; give presentations at conferences; and contribute to proposals and progress reports. For more information, please see: http://user.astro.columbia.edu/~savin/index.html. The appointment is initially for one year, with the possibility of renewal for up to two additional years; this is contingent upon the availability of funds and mutual satisfaction. The successful candidate will have a Ph.D. or the equivalent degree in Planetary Science, Physics, Geology, Astrophysics, or a related field. At least three years of postdoctoral experience is required. Experience in laboratory studies of the interaction of solar wind ions with planetary materials, as well as surface science and surface characterization, is preferred. Desired laboratory skills include experience with apparatus design and construction; fast ion beams; ion optics; ultra-high vacuum techniques; ultraviolet, visible, and near infrared spectral reflectance measurements; quadrupole mass spectrometers; catcher foils; X-ray photoelectron spectroscopy; X-ray diffraction; and associated electronics. Desired computer skills include programming, multidimensional data analysis, LabView, Python, Autodesk Inventor, Solidworks, SIMION, Linux/Mac OS, and Windows OS. The successful candidate will have a strong background in at least some of the areas listed above, a proven research ability, and evidence of future research potential. The candidate is expected to be able to work well independently and cooperatively with a team and to communicate the results of his/her research both orally and in writing. Demonstrated written and oral communication skills are highly desirable. Questions regarding this position can be addressed to Dr. Savin at firstname.lastname@example.org. All applications must be submitted through Columbia University’s Recruitment of Academic Personnel System (RAPS). Applicants should submit a cover letter, curriculum vitae (including a list of publications), a statement of past research and arrange to have three reference letters uploaded to RAPS. Applications will only be considered after all materials have been received. The application screening process will begin immediately, and will continue until the position is filled.
