Postdoctoral Research Associateship: Nanomaterials/Neuroscience/Biophysics

US Naval Research Laboratory, Washington, District of Columbia

Position Description:

A postdoctoral research position is available immediately in the Center for Bio/Molecular Science and Engineering at the US Naval Research Laboratory, Washington DC ( project, at the intersection of nanoscience and neuroscience, is aimed at the development of actuatable nanomaterial-based bioconjugates for the control of cellular membrane potential.

Our laboratory utilizes various nanomaterials (quantum dots, gold nanoparticles), molecular biology, protein and peptide engineering, FRET and cell biology to understand how to implement functional nanobioconjugates at the biotic/abiotic interface for the purposes of cellular labeling, imaging and sensing. This position presents an opportunity to work with a highly interdisciplinary group to create new types of nanomaterial-based sensors. This position is outside the NIH.


The successful candidate will possess a multidisciplinary skill set including proficiency in the following:  cell culture (neuronal cell culture experience is desired but not required), quantitative cellular imaging, fluorescence and/or confocal microscopy and biophysics. A strong background and documented experience in molecular and cellular biology is essential. 
The Naval Research Laboratory is the Department of Defense’s corporate laboratory for the Navy and Marine Corps. The Center for Bio/Molecular Science and Engineering works at the interface of materials, chemistry, biology, biophysics and materials science to solve critical problems of importance to the Navy and DoD.
Availability: Immediately (no deadline date)
Salary: ~$77k/year with health benefits, conference travel allotment and relocation reimbursement.
Applicants must be either a US citizen or permanent resident/green card holder.
Fellowship is administered by either the National Research Council (NRC, or American Society for Engineering Education (ASEE, and the PhD must have been awarded within 5 yrs (NRC) or 7 yrs (ASEE) of the time of application.
