The Lawrence Berkeley National Laboratory has an opportunity for a Computational Biologist Postdoctoral Fellow as part of a project that will involve writing the software to process X-ray diffraction patterns from protein crystals analyzed on the free-electron laser at Linac Coherent Light Source. The successful candidate will be the primary developer of new methods for this data processing. While protein crystallography methods for traditional rotation geometry experiments are well-established, LCLS data will be acquired with completely different optics and geometry, and at 100-fold higher rate. Both the underlying physics and the wide range of user needs will need to be accounted for. Durable computer code will then be implemented in an object-oriented framework, using both C++ and Python scripting. We are seeking applicants with a recent Ph.D. in Computational Biology, Computer Science, Biophysics, Applied Mathematics, or related areas. Clear written expression in the form of co-authored publications and/or computer documentation is a must. Key success factors include a proficient understanding of network architecture and parallel processing, and experience with forefront approaches such as GPU computing. GUI development experience is also important, as a focus will be on creating systems to interpret the results in real time. Applicants are invited to post a cover latter and CV for job listing #25178 at http://jobs.lbl.gov/details.asp?jid=25178&p=1
