Senior Research Associate – Anomalous Small Angle Scattering (ASAXS)

The University of Chicago Pritzker School of Molecular Engineering is seeking a full time Senior Research Associate (SRA) to become part of NSF’s ChemMatCARS.

Anomalous Small Angle Scattering (ASAXS) is one of the most powerful synchrotron Xray techniques for element-specific structural study of soft matter systems. It is indispensable for understanding quantitative structural heterogeneities in soft matter systems and nanomaterials. The successful candidate will be expected to lead an ASAXS user program that will serve a general scientific user community. The candidate will be expected to originate and engage in collaborative efforts in ASAXS studies of a variety of soft matter systems with ChemMatCARS users. These efforts include, but are not limited to, conducting synchrotron experiments with users at ChemMatCARS, analyzing ASAXS data, contributing to manuscripts for publication, and, if the situation applies, contributing to grant proposal applications. In addition, this candidate will be expected to provide additional support for scientists conducting research at ChemMatCARS, as well as lead R&D efforts to expand the capabilities of ChemMatCARS in the use of ASAXS. Areas of investigation include, but are not limited to, aggregation and complexation of polyelectrolytes, interactions between charged colloids and macro-ions in solutions, and element distribution within functional nanomaterials at the length scales from a few to hundreds of nanometers.
