A postdoctoral position is available in the laboratory of Dr. Marc Raphael in the Biosensors and Electronics Section of the Naval Research Laboratory in Washington DC.  Our research focuses on the development of quantitative techniques for cellular and molecular biology that merge state-of-the-art nano- and micro-lithography with traditional light microscopy, with a particular focus on wound healing applications.   Live cell based programs currently include (1) the use of plasmonic nanostructures for the spatio-temporal mapping of protein and exosome secretions from individual cells in real time and (2) nanopatterned surfaces for directing cell migration and investigating surface adhesion mechanisms.


The successful candidate must be interested in multi-disciplinary research.  Experience in several of the skill sets listed below is highly encouraged and motivation to learn new skills is critical. 


Cell Biology and Data Analysis

Cell culturing, live cell microscopy (fluorescence, phase contrast, DIC), Matlab.


Techniques in preparing surfaces for conjugation and reproducible biofunctionalization with antibodies, peptides and DNA. Characterization with surface plasmon resonance, localized surface plasmon resonance and fluorescence.

Micro and Nanolithography

Optical lithography, reactive ion etching, electron beam nanolithography, electron beam and thermal evaporation based thin film deposition, scanning electron microscopy, atomic force microscopy.


Career Development

We place special emphasis on the career development of our postdocs. Every effort is made to match each postdoc’s career goals with the skill sets acquired at NRL.  We also provide funding for courses and workshops, allowing our postdocs to branch out into new areas of interest or gain additional expertise in a particular discipline.
