POST-DOCTORAL RESEARCH POSITIONS ANNOUNCEMENT

Cooperative Program: NIST Center for Nanoscience and Technology/University of Maryland

TITLE: Research Associate

Position 1:

Applications are invited for postdoctoral fellowships in research in nanotribology and nanomanufacturing. The goal of this research is to develop a detailed understanding of the origins of atomic scale frictional energy dissipation and to apply this knowledge toward the design of novel nanomanufacturing devices and systems. Projects will employ state-of-the-art atomic force microscopes (AFMs) and probe devices to measure nanoscale forces. Experience with ultra-high vacuum techniques, in situ surface preparation, low- or variable-temperature AFM or another scanning probe microscopy is strongly preferred. Applicants must have a Ph.D. in Physics, Chemistry, Materials Science, or a related field. For information, please contact the Project Leader, Rachel Cannara (rachel.cannara@nist.gov).

Position 2:

Applications are invited for postdoctoral fellowships in in the area of fluorescent nanoparticle tracking with feedback control. We are developing real-time feedback methods that enable an experimenter to observe individual fluorescent nanoparticles diffusing and tumbling in a liquid without allowing them to leave the diffraction-limited observation volume of a fluorescence microscope. The feedback control signal reports the particle’s position, while the fluorescence signal is sensitive to other internal and external dynamics such as mechanical deformation (bending), orientation, and inter-particle interactions. This uniquely sensitive measurement tool will have many applications in areas of nanotechnology that utilize non-spherical or non-rigid nanoparticles. The postdoctoral scholar will:

Contribute to the design and construction of an experimental apparatus, based on a fluorescence microscope, for three-dimensional tracking of fluorescent nanoparticles using active feedback control.
Fabricate fluorescently-labeled polymer nanoparticles, by completing appropriate training and following established fabrication protocols in the CNST NanoFab.
Apply statistical methods to understand the fundamental limits of experimental techniques and measurement methods.
Report research results, through oral and poster presentations, and by publication in refereed journals.

Applicants should have a Ph.D. in physics or a related field, preferably with experience in one or more of the following areas: single-molecule spectroscopy, single-particle tracking, feedback control. For information, please contact Dr. Andrew Berglund (andrew.berglund@nist.gov).

APPLICATIONS:

Applications should then be submitted to the appropriate staff member listed above with a cc to: Alice Mobaidin, mobaidin@umd.edu. The application should include a curriculum vitae (including a list of publications), , and a list of three references.

Additional openings in the program are likely to be available on a continuing basis. Interested parties should review the program web sites (http://cnst.nist.gov/about_res.html and http://cnst.nist.gov/postdoc_cnst.html) .
