XFEL Biophysics Postdoctoral Researcher
The Department of Physics at Arizona State University (ASU) seeks applicants for 2 postdoctoral researcher positions for the development of algorithms for biological X-ray free electron laser (XFEL) data, both in crystallography and solution scattering. The successful applicants will become part of an interdisciplinary team at ASU working on solving important biological questions using XFELs. This is a two-year Postdoctoral appointment with the possibility of extension to a maximum of three years.
Major advances in structural biology have often resulted from novel approaches to data collection and analysis. Historically, increasingly powerful X-ray sources led to great leaps in the ability to obtain information about structures of biomolecules, which is critically related to the molecules' biological function. Serial femtosecond crystallography (SFX), a novel extension of crystallography making use of the extreme flux and ultra-short duration of XFEL pulses, has produced new insights into important biological questions over the last 5+ years. XFEL experiments with biological targets typically require very large volumes of data and thus a correspondingly large volume of scarce, precious protein, to obtain high-resolution molecular structures. Furthermore, XFEL facilities typically host only one or two experiments simultaneously, and only two XFELs presently serve the global user community, with a few more will be coming online in 2017. The number of biological targets that can be studied and the rate of discoveries can be dramatically increased through the development of innovative, advanced algorithms that reduce the number of necessary measurements and extract more information from the samples by fully exploiting the information content that is unique to XFEL diffraction, and by extending XFEL use to uncrystallized targets.
The objective of these postdoctoral researcher positions is to develop algorithms for improving data accuracy in SFX through modeling and optimization, develop novel phasing methods which exploit the full spatial coherence of the XFEL for 2D and 3D nanocrystals, and/or develop structure-determination methods that can be applied to samples that cannot be crystallized, through XFEL fast solution scattering.
Essential Functions of the position:
- Develop improved algorithms and software for analyzing biological XFEL data (static and time-resolved crystallographic or solution scattering data).
- Analyze and present results at conferences, workshops, seminars and technical meetings.
- Document and publish research results in peer-reviewed scientific or technical journals.
- Contribute to XFEL data analysis workshops organized by the Group
The successful candidates are expected to support the analysis of serial femtosecond crystallography experiments at the Linac Coherent Light Source (LCLS), SPring-8 Angstrom Compact free electron Laser (SACLA), the European X-Ray Laser (XFEL), or other applicable x-ray sources (XFELs or 3rd generation synchrotrons). This work is complementary to XFEL data analysis work in the NSF BioXFEL Science and Technology center (STC), and so the candidates will interact and collaborate with students and postdoctoral researchers working in the BioXFEL STC. They will report to the PI for the project.
