Postdoctoral positions are available immediately in the *Structural Biology Laboratory* headed by *Dr. C. S. Raman* at the University of Maryland, Baltimore. Research in the Raman laboratory combines structural, biophysical, biochemical, and cell biological approaches to understand the molecular mechanisms underlying cellular signaling. The laboratory is equipped with state-of-the-art equipment for fermentation, high-throughput protein expression, purification, crystallization (liquid handlers for screen generation and optimization, Mosquito LCP robot, and crystal imaging systems), X-ray diffraction, and high definition mass spectrometry (Synapt G2 HDMS). In addition, we have ready access to synchrotron facilities. For a representative example of our work, please consult*:* *Nature 455: 363-368*. Applicants should hold a PhD in biochemistry, biophysics, chemistry, molecular biology, or a closely related field. Applicants should have experience in protein crystallography as well as a good publication record. Strong background in protein expression and biophysical characterization is essential. Expertise in membrane protein purification is a plus. Furthermore, strong communication skills in oral and written English are required. To apply, please, send a letter of interest, a CV, and names of three references by e-mail to: [email protected]
