Research Associate B - NASA

Research Associate B: This is a term position of nine months to a maximum of three years to provide professional development opportunities in the research field. Expected start date of Spring - Summer 2025.

The qualified Research Associate will conduct experimental work that supports two NASA projects (Programs: Habitable Worlds, ColdTECH) focused on the thermophysical and biogeochemical properties of planetary analog ices relevant to ice-ocean worlds, such as Europa and Enceladus. The researcher will carry out this work in Dartmouth's state-of-the-art Ice Research Lab in collaboration with Dr. Jacob Buffo and members of his research group. Specific tasks associated with this projects include: 1) the culturing of psychrophilic and halophilic organisms for use in experiments that will investigate their entrainment in and dynamic interaction with planetary analog ices, 2) the growth and sample handling of organic and organism rich planetary analog ices in the lab via established top-down growth techniques, 3) the biogeochemical analysis of the composition, microbial distribution, and microbial activity in the resultant ice columns using geochemical and epifluorescent microscopy techniques, 4) fabrication of ice samples containing fiberoptic tethers and subsequent testing of the ice adhesion properties of the tethers via uniaxial load testing. The Research Associate will lead the paper writing efforts related to the experimental work they conduct and will be expected to present their results at topical academic conferences. Additionally, as a part of professional development, the Research Associate is expected to pursue continued/future funding by writing grant proposals and applications.

Note: Continuing employment is based on availability of grant funds
