Postdoctoral Fellows

HAO offers two-year postdoctoral fellowships to early career Ph.D. scientists interested in theoretical, experimental and observational studies of the Sun and Earth’s upper atmosphere. The HAO postdoc program is closely coordinated with the postdoc program of NCAR’s Advanced Study Program (ASP) and HAO postdocs will receive the same salary and benefits as ASP postdocs.

Fields of Research

Successful applicants will pursue research, in collaboration with members of the HAO scientific staff, on a wide range of topics, including study of the Earth’s ionosphere, thermosphere, and magnetosphere, observations and simulations of coronal mass ejections, spectro-polarimetric observations and interpretation using HAO instrumentation and data inversion tools, probing solar magnetism through observations and modeling, and instrument development. Projects involving radiative transfer, hydrodynamics, magnetohydrodynamics, radiation hydrodynamics, plasma physics, and other topics are pursued both out of fundamental physical interest and for their application to the above areas of research.

Terms of Appointment

Postdoctoral Fellows are appointed for two years beginning in September or October; some flexibility is possible on the specific times of arrival and departure. Fellows are expected to work at HAO in Boulder, Colorado, with the exception of time spent participating in field research and observing programs. Fellows will have access to state-of-the-art observational and computational facilities in support of their research. These include the Mauna Loa Observatory in Hawaii and the NCAR-Wyoming Supercomputing Center (NWSC), as well as local Unix workstations, data archives, and libraries at HAO/NCAR.

How to Apply

THE DEADLINE TO SUBMIT APPLICATION MATERIALS HAS PASSED. The next recruitment period will begin later this year. Please check back to our website in fall 2018.

HAO Fellowships will be granted on the basis of proven scientific ability and relevance to HAO research programs. Applications will be accepted through the Advanced Study Program (ASP). Applicants who specify HAO as a host laboratory will automatically be considered for both fellowships, and initial offers will be made in early March. Additional offers may also be made later in the spring. All application materials must be submitted as PDF files. See the ASP website for complete application details.
